Chargeback Types Explained: Fraud, No Authorization, and Friendly Fraud

The Merchant Guide Banks Use (But Never Show You)

Every time a chargeback hits your merchant account, it feels the same.

Your stomach drops.
Your Stripe, PayPal, or Shopify dashboard flashes red.
Your revenue for the day evaporates — and you haven’t even had a chance to explain yourself.

But here’s what most U.S. merchants never realize:

Not all chargebacks are created equal.

Banks secretly divide disputes into different “buckets,” and each bucket follows its own hidden logic, rules, and win-rate math. If you don’t know which bucket your dispute falls into, you will almost always lose — even when the customer is obviously lying.

This guide exposes exactly how banks classify chargebacks into three major types:

• Fraud

• No Authorization

• Friendly Fraud

And more importantly, how each one must be fought differently if you want to win.

If you sell anything online in the United States — digital products, physical goods, SaaS, subscriptions, coaching, courses, or e-commerce — this knowledge is the difference between running a profitable business and watching your account slowly bleed out from the inside.

Why Chargeback Type Matters More Than Whether You’re “Right”

Merchants often believe that chargebacks are about truth.

They’re not.

Chargebacks are about category.

When a customer disputes a transaction, the bank immediately assigns a reason code. That reason code locks the case into a specific chargeback type, which determines:

• What evidence is allowed

• How much evidence is required

• Which party carries the burden of proof

• How likely you are to win

• Whether the issuer will even look at your documents

Two merchants can have the exact same transaction.

One wins.
The other loses.

The difference?
Chargeback type.

Let’s pull the curtain back.

The Three Chargeback Types That Control Every Dispute

Banks and card networks don’t describe chargebacks in emotional terms like “customer lied” or “merchant was wrong.”

They classify them as:

1. Fraud chargebacks

2. No authorization chargebacks

3. Friendly fraud chargebacks

Each one is treated as a completely different legal universe.

If you respond to the wrong universe, you automatically lose.

Let’s break them down.

Type 1 — Fraud Chargebacks

(“I didn’t make this purchase”)

Fraud chargebacks are the most dangerous category for merchants.

They sound simple:

“Someone used my card without my permission.”

But behind the scenes, this accusation triggers an entirely different legal standard.

What Banks Mean by “Fraud”

When a bank receives a fraud claim, they are not asking:

“Did the merchant do something wrong?”

They are asking:

“Was the cardholder involved in the transaction?”

If the cardholder says no, the default assumption becomes:

The transaction is unauthorized.

That flips the burden of proof.

Instead of the cardholder proving fraud, you must prove identity.

And proving identity after the fact is brutally difficult.

The Hidden Logic of Fraud Chargebacks

Banks operate on one core belief:

“A cardholder knows if they made a purchase.”

So if a cardholder says they didn’t, the bank starts with:

“We believe them.”

Now you must prove one of three things:

• The cardholder actually made the purchase

• Or someone authorized by them did

• Or the claim is false

That requires evidence of who was on the other side of the screen.

Not just what was sold.
Not just that it was delivered.
But who made the purchase.

That’s why fraud disputes are so deadly for:

• Digital products

• SaaS

• Downloads

• Online services

• Remote consulting

• Coaching

• Subscriptions

You didn’t see the person.
You didn’t scan their ID.
You didn’t swipe a chip card.

So unless you collected deep identity data, the bank assumes you can’t prove it.

What Counts as Proof in a Fraud Case

Banks and card networks only recognize a narrow set of identity signals:

• IP address

• Device fingerprint

• Login history

• Account registration

• Previous successful transactions

• Shipping address (for physical goods)

• AVS and CVV match

• 3-D Secure or OTP authentication

If you don’t submit these, the bank assumes:

“Merchant failed to verify cardholder.”

And you lose — even if the customer used your product for months.

Real Example: SaaS Founder Loses $18,000

A SaaS founder sold annual subscriptions at $1,200 each.

One user purchased 15 seats.

Three months later, the cardholder filed fraud.

They claimed their employee “never had permission.”

The merchant submitted:

• Invoices

• Login history

• Support emails

• IP logs

• Usage records

The bank rejected everything.

Why?

Because the cardholder said they didn’t authorize the purchase.

And there was no 3-D Secure or signed authorization.

$18,000 gone.

Account risked.

Not because the founder was wrong — but because the case was labeled fraud.

Type 2 — No Authorization Chargebacks

(“I didn’t approve this transaction”)

No authorization is often confused with fraud, but it is a different legal creature.

Fraud says:

“Someone stole my card.”

No authorization says:

“I didn’t approve this charge.”

That could mean:

• A spouse used the card

• An employee made a purchase

• A child clicked a button

• A recurring charge happened

• A free trial turned paid

The bank treats this very differently.

Why No Authorization Is Easier to Win

In no-authorization cases, the bank is not looking for identity.

They are looking for consent.

That means your job is to prove that the cardholder (or someone with authority) agreed to the charge.

This opens the door to evidence like:

• Terms of service

• Checkout screenshots

• “I agree” boxes

• Subscription confirmation

• Emails

• Login records

• Prior payments

• Cancellation policies

You are not proving who they are.
You are proving what they agreed to.

That’s a massive difference.

The Mistake That Destroys Merchants Here

Most merchants fight no-authorization disputes like fraud cases.

They send IPs and logs.

Banks ignore them.

They wanted to see:

Where did the customer agree to be charged?

If you show:

• The checkout flow

• The price

• The terms

• The billing schedule

• The refund policy

You often win.

If you don’t, you lose — even if the customer obviously used the product.

Type 3 — Friendly Fraud

(“I know I bought it… but I want my money back”)

This is the silent killer.

Friendly fraud makes up over 60% of all chargebacks in the U.S.

It happens when:

• The customer forgot they bought

• The customer didn’t recognize the descriptor

• The customer regretted the purchase

• The customer didn’t read the terms

• The customer couldn’t get a refund

• The customer didn’t want to talk to support

So they call the bank instead.

To the bank, it looks like fraud or no-authorization.

To you, it looks like theft.

Why Friendly Fraud Is So Hard to Stop

The card networks don’t have a “buyer’s remorse” category.

So friendly fraud is disguised as:

• Fraud

• No authorization

• Not as described

• Unrecognized charge

Which means you are forced to fight it inside those systems — even though the truth is completely different.

The Psychological Weapon Customers Use

Banks train consumers to do this.

They say:

“If you don’t recognize a charge, call us.”

Not:

“Contact the merchant.”

That pushes honest people into committing fraud without realizing it.

And once the bank files the dispute, the machine takes over.

Why Merchants Lose When They Treat All Chargebacks the Same

Most merchants respond to every chargeback with:

• Receipts

• Tracking

• Logs

• Angry explanations

Banks don’t care.

They only care if the evidence matches the type.

Wrong type = automatic loss.

That’s why high-level chargeback defense isn’t about writing more — it’s about writing the right things.

The Bank’s Internal Playbook (What They Never Tell Merchants)

Every dispute is processed through this silent flow:

1. Cardholder chooses a reason

2. Bank assigns a reason code

3. Reason code determines chargeback type

4. Chargeback type determines evidence rules

5. Evidence is filtered

6. Decision is made

Merchants only see step 6.

By then, it’s too late.

How to Identify Which Type You’re Facing

Before you fight anything, you must decode the reason code.

Here are the most common U.S. mappings:

Fraud

• Visa: 4837

• Mastercard: 4837

• AmEx: F29

• Discover: UA01

No Authorization

• Visa: 4837 (sub-category)

• Mastercard: 4837

• AmEx: No Cardholder Authorization

Friendly Fraud (hidden)

• Visa: 4837, 4863, 4855

• Mastercard: 4841, 4855

• AmEx: No Show, No Return

The label is different — the damage is the same.

What You Should Submit for Each Type

This is where merchants either win or get destroyed.

For Fraud

You must prove identity:

• IP match

• Device match

• Account history

• Prior transactions

• 3-D Secure

• Shipping address

For No Authorization

You must prove consent:

• Checkout screenshots

• Terms acceptance

• Subscription confirmation

• Email receipts

• Cancellation policy

For Friendly Fraud

You must prove behavior:

• Usage logs

• Login history

• Downloads

• Customer support emails

• Refund policy

• Prior disputes

Mix these up and the bank will ignore you.

Why Stripe, PayPal, and Shopify Don’t Teach This

Payment processors don’t want you to win too many disputes.

They profit from fees and risk margins.

So they give you generic tools — not strategy.

That’s why most merchants lose 70–80% of chargebacks.

Not because they’re wrong.

Because they’re blind.

The Compounding Damage of Losing Chargebacks

One lost chargeback doesn’t just cost the sale.

It causes:

• Higher processing fees

• Rolling reserves

• Account monitoring

• Payout delays

• Shutdown risk

• Blacklisting

Banks don’t forgive patterns.

They punish them.

How Smart Merchants Build Chargeback Armor

They don’t wait for disputes.

They design their funnel to produce:

• Fraud-proof data

• Authorization proof

• Behavior evidence

So when a chargeback hits, they already have the file.

That’s how high-risk industries survive:

• Supplements

• Coaching

• Info products

• Subscriptions

• Crypto

• SaaS

They don’t guess.

They prepare.

The Evidence Stack Banks Respect

Winning merchants keep:

• Checkout page screenshots

• Timestamped terms

• IP logs

• Account history

• Payment descriptors

• Cancellation records

• Support tickets

• Usage metrics

All tied to each transaction.

That’s not paranoia.

That’s survival.

What Happens When You Use the Right Evidence

Your win rate jumps from 20% to 60%+.

Your processor trusts you.

Your reserve disappears.

Your account becomes stable.

Your cash flow stops bleeding.

And That’s Why We Built the Chargeback Evidence Kit USA

Most merchants don’t lose because they sold something bad.

They lose because they don’t know what to send.

The Chargeback Evidence Kit USA gives you:

• Exact templates for each chargeback type

• Bank-approved language

• Evidence checklists

• Screenshot examples

• Reason-code playbooks

• Submission scripts

It turns your disputes into legal-grade case files.

Not emotional appeals.

Not random uploads.

But the same style of documentation banks use internally.

You don’t need a lawyer.
You need the right evidence in the right format for the right chargeback type.

And once you understand that, chargebacks stop being scary — they become winnable.

At the end of this guide, you’ll see exactly how to use it to protect every dollar you earn…

…but first, you need to understand how these three chargeback types evolve inside the banking system, how issuers train customers to misuse them, and why friendly fraud is silently becoming the biggest threat to U.S. online businesses, especially in SaaS, subscriptions, and digital goods — because what looks like “fraud” on paper is often something much darker:

a customer who knows exactly what they’re doing when they click “dispute,” and is betting that you won’t know how to fight back, because once the bank flags a transaction as unauthorized, the entire legal framework changes, and suddenly the merchant becomes the one who has to prove innocence instead of the cardholder having to prove guilt, which creates a power imbalance that savvy consumers have learned to exploit, and it’s why so many otherwise honest buyers are now using their banks as a free refund button instead of contacting support, because they know the system is stacked in their favor, and because processors quietly encourage this behavior by making chargebacks easier than refunds, which leads to a vicious cycle where more disputes create stricter merchant rules, which creates more friction for real customers, which pushes even more people into filing disputes instead of talking to you, and that cycle continues until entire industries are labeled “high risk” and buried under monitoring programs, rolling reserves, and sudden account shutdowns, and the only way to survive inside that system is to understand not just the three chargeback types, but the psychology, incentives, and financial machinery behind them, because once you see how banks actually think about fraud, authorization, and consumer protection, you realize that the dispute process isn’t designed to be fair — it’s designed to be efficient for banks, profitable for networks, and simple for cardholders, which means merchants are always the last priority unless they force themselves to be heard with the kind of structured, undeniable evidence that leaves the issuer no choice but to side with you, which is why in the next section we’re going to go deeper into how each chargeback type is created at the moment the cardholder makes that phone call or clicks that button inside their banking app, because that single choice — fraud versus no authorization versus unrecognized charge — determines everything that happens next, and most customers have no idea they are selecting your fate with a single tap, while you’re sitting on the other side of the screen completely unaware that your business is about to be judged by a rulebook you’ve never been allowed to see, and that’s where things get truly dangerous for merchants who think chargebacks are just a customer service issue instead of a financial risk system that can erase years of work in a matter of weeks if you don’t know how to operate inside it, because once a dispute enters the network, it doesn’t care about your intentions, your honesty, or your effort — it only cares about which box was checked, which code was assigned, and whether the evidence you submit matches the invisible requirements attached to that code, and that is exactly why so many merchants lose even when they are right, because they are playing chess while the banks are playing a completely different game, and if you want to survive in e-commerce, SaaS, and digital sales in the United States, you have to learn that game or it will quietly destroy your revenue one chargeback at a time, starting with the next dispute that hits your dashboard and ends with you wondering how a business that was profitable on paper suddenly collapsed under a wave of “fraud” that wasn’t really fraud at all but a system that was never built to protect you in the first place, and that’s why understanding these three chargeback types is not just a technical skill but a survival skill, because once you master it, you stop being a passive victim of the dispute machine and start becoming someone who knows exactly how to push back, document, and win inside the same framework banks use to judge every transaction, which brings us to the next critical question that every merchant needs to ask themselves before the next chargeback hits: what exactly happens inside the bank when a cardholder clicks “dispute,” and how does that one decision cascade through the card network to determine whether you get your money back or not, because until you see that process from the inside, you’re fighting blind, and in the next section we’re going to pull apart that entire chain of events step by step, starting with the moment the customer opens their banking app and selects a reason, and ending with the silent algorithms and human reviewers who decide whether your evidence is even worth looking at, which is where most merchants unknowingly fail, because the system isn’t judging you on fairness — it’s judging you on whether you knew how to play by its hidden rules, and most don’t, which is why they keep losing, over and over again, until they either give up, shut down, or finally realize that chargebacks aren’t random at all, they’re predictable, exploitable, and winnable if you know exactly how to approach each type, and that’s what we’re about to dive into next, starting with how issuers actually train cardholders to describe transactions in ways that automatically shift the burden of proof onto you, and how that training has quietly created the explosion of friendly fraud that is now the number one killer of U.S. merchant accounts, because what used to be rare has become normal, and what used to be abuse has become standard behavior, and unless you understand how that shift happened, you won’t be able to protect yourself from it when it hits you next, which it will, because if you sell online long enough, every merchant becomes a target, not because they did something wrong, but because the system makes it profitable for customers to do the wrong thing, and that is the uncomfortable truth about chargebacks in America today, and it’s exactly why the merchants who survive are not the ones with the best products, but the ones who understand the rules of this invisible war and prepare their evidence before the first shot is even fired, which is what we’re going to break down in the next part, where we’ll follow a real dispute from the cardholder’s phone to your processor’s risk department, to the issuing bank, to the network, and finally back to you, so you can see exactly where the battle is actually fought, and why by the time you’re notified, half the game is already over if you didn’t build your systems the right way from the beginning, because in this ecosystem, prevention and documentation matter more than apologies and explanations, and once you see that, you’ll never look at a chargeback the same way again, because you’ll understand that every dispute is not just a complaint — it’s a structured legal challenge inside a financial system designed to favor the side with the cleanest paperwork, and that can be you if you know what to do, which we’re about to explore in relentless detail as we continue…

continue

…as we continue by stepping inside the issuer’s world and watching what really happens after a cardholder presses that deceptively simple “Dispute this charge” button, because that click is not just a complaint, it is a trigger that launches a multi-billion-dollar risk engine into motion, and once it starts turning, it doesn’t care about your story, your screenshots, or how unfair the situation feels — it only cares about how the transaction fits into its predefined categories, and understanding those categories is how you turn a losing fight into a winning one.

What Actually Happens Inside the Bank When a Chargeback Is Filed

From the merchant’s perspective, a chargeback feels like something that suddenly “appears” in Stripe, PayPal, or your acquiring bank dashboard.

From the bank’s perspective, it is the final step of a process that began much earlier.

Here is what happens in reality.

A cardholder opens their banking app or calls the number on the back of their card. They see a list of transactions. One looks unfamiliar, unwanted, or simply regretted. They tap it.

At that moment, the bank does not ask,
“Did you contact the merchant?”

They ask something much more dangerous for you:

“Why don’t you recognize this charge?”

The options usually look like:

• I didn’t make this purchase

• I don’t recognize this merchant

• I was charged after canceling

• The amount is wrong

• I didn’t receive what I paid for

Each of these options maps to a different internal reason code.

Each reason code maps to a different chargeback type.

And that is the moment your fate is sealed.

Most cardholders have no idea they are choosing between fraud, no authorization, or friendly fraud. They think they are just explaining a problem.

The bank is silently classifying your business.

How One Click Turns a Refund Into an Accusation

Here is the brutal truth:
If the customer chooses “I didn’t make this purchase”, you are now accused of processing a fraudulent transaction.

If they choose “I don’t recognize this merchant”, you are accused of misleading billing.

If they choose “I was charged after canceling”, you are accused of unauthorized billing.

None of these are neutral.

All of them trigger automated assumptions inside the card network.

That is why two customers with the exact same complaint can generate two completely different cases — one winnable, one almost impossible.

This is not about fairness.
This is about classification.

The Issuer’s Priority Is Not You

Issuing banks have three primary goals:

1. Keep the cardholder happy

2. Minimize fraud liability

3. Keep the network flowing

Merchants are fourth.

That means when a cardholder files a dispute, the bank is not trying to investigate what really happened. They are trying to move the case into the fastest, safest category for themselves.

Fraud is the fastest.

That is why banks subtly nudge customers toward fraud-style language.

“Did you make this purchase?”
“No.”

Boom. Fraud.

Even if the truth is, “I bought it but I want my money back.”

How Friendly Fraud Becomes Real Fraud in the System

This is where friendly fraud becomes lethal.

The customer may know they bought it.
The bank only sees the reason code.

Once that code is assigned, the case is treated exactly the same as if a criminal stole the card.

Your evidence must now prove identity — not satisfaction, not delivery, not usage.

Most merchants cannot do that.

So they lose.

And the customer gets a refund.

And the bank looks like a hero.

This is why friendly fraud has exploded in the U.S.

Because the system rewards it.

Why Banks Love the Fraud Bucket

Fraud cases are simple for banks.

They debit the merchant.
They credit the cardholder.
They mark the transaction as unauthorized.
They move on.

No negotiation.
No messy merchant arguments.
No refund policies.

That simplicity is why fraud is overused.

The Silent Filters That Kill Your Evidence

When you upload documents in Stripe or PayPal, you think a human reads them.

Most of the time, that’s not what happens.

Your evidence goes through automated filters first.

Those filters check:

• Does this evidence match the chargeback type?

• Is it on the approved list for this reason code?

• Does it contain required data fields?

If not, it is ignored.

Not rejected.
Not debated.
Ignored.

You can upload 200 pages of proof and still lose if it’s the wrong type of proof.

That is why merchants scream,
“They didn’t even look at my documents!”

They didn’t.

They weren’t allowed to.

Why Your Tracking Number Doesn’t Matter in a Fraud Case

If the case is fraud, the bank is not asking,
“Did you ship it?”

They are asking,
“Who did you ship it to?”

If you don’t prove that the cardholder was the recipient or authorized the recipient, the delivery is irrelevant.

That is why so many physical product merchants lose fraud chargebacks even with signature confirmation.

The bank doesn’t care if someone signed.

They care if the cardholder signed.

Why Your Login Logs Don’t Matter in a No Authorization Case

If the case is no authorization, the bank is not asking,
“Did someone use the account?”

They are asking,
“Did the cardholder agree to be billed?”

You can show a hundred logins.

If you don’t show where they agreed to pay, you lose.

Why Your Refund Policy Doesn’t Matter in a Fraud Case

Fraud overrides contracts.

If the bank believes the cardholder didn’t authorize the transaction, your terms of service are meaningless.

That is why merchants are shocked when their clear no-refund policy is ignored.

They are fighting the wrong war.

The Real Battlefield: Reason Codes

Every chargeback has a reason code.

That code determines everything.

Here is what most merchants never see:

Behind Visa, Mastercard, AmEx, and Discover are hundreds of sub-codes that define exactly what evidence is allowed.

For example:

• Visa 10.4 = Fraud, No Cardholder Authorization

• Visa 12.6 = Duplicate Processing

• Visa 13.3 = Not as Described

• Mastercard 4837 = No Cardholder Authorization

• Mastercard 4841 = No Show or CC Absence

Each one has its own rulebook.

If you don’t match it, you lose.

How to Reverse-Engineer the Type From the Code

When you see a dispute in your processor, it will show something like:

“Reason: Fraud”
or
“Reason: No Authorization”
or
“Reason: Unrecognized”

But behind that is a network code.

That is what you must build your response around.

High-level merchants don’t respond to “fraud.”

They respond to Visa 10.4 or MC 4837.

Because those codes tell you:

• What proof is required

• What proof is banned

• What proof is optional

The Three Evidence Universes

Think of chargebacks as three different courtrooms.

Fraud Court

You are accused of processing a stolen card.

The judge only accepts identity evidence.

No Authorization Court

You are accused of charging without consent.

The judge only accepts agreement evidence.

Friendly Fraud Court (disguised)

You are accused of something that didn’t really happen.

The judge accepts behavioral evidence — but only if you frame it correctly.

Walk into the wrong courtroom with the wrong documents and you automatically lose.

Why Processors Don’t Explain This

Stripe, PayPal, and Shopify don’t teach you this because:

• It’s complex

• It increases their support load

• It makes merchants argue

• It exposes how stacked the system is

So they give you a single “believe in yourself” upload box and let you fail.

The Merchants Who Win Are Playing a Different Game

High-volume merchants, high-risk verticals, and subscription businesses don’t guess.

They build:

• Fraud stacks

• Authorization logs

• Behavior tracking

So when a dispute hits, they already know:

“This is Visa 10.4. Send identity.”
“This is MC 4841. Send contract and attendance.”

That is how they keep win rates above 60%.

The Cost of Not Knowing

If you fight fraud like friendly fraud, you lose.

If you fight no authorization like fraud, you lose.

If you fight friendly fraud like no authorization, you lose.

That’s why the average merchant win rate hovers around 20–30%.

They’re throwing darts in the dark.

What We’re Going to Do Next

Now that you understand how the system actually classifies disputes, the next step is to go deeper into each of the three chargeback types and show you, in brutal, practical detail:

• How they are triggered

• What banks secretly expect to see

• How merchants accidentally sabotage themselves

• And how to structure evidence that actually wins

We are going to start with the most dangerous one of all — fraud chargebacks — because this is where the most money is lost, the most accounts are shut down, and the most honest merchants are destroyed simply because they didn’t know how the rules worked when a customer clicked the wrong button, which is exactly what we are going to dissect next by following a real fraud dispute from the first moment the cardholder complains all the way to the final decision, so you can see every place where merchants usually fail and where you can start winning instead, because once you understand fraud at this level, the other two types become much easier to handle, and that’s when chargebacks stop feeling like random attacks and start feeling like something you can actually control, which is where your power as a merchant truly begins, and that brings us directly into the heart of the problem — the anatomy of a fraud chargeback, how it’s built, how it’s judged, and how to survive it — which we’re diving into right now, starting with the moment a cardholder says those three words that can cost you thousands of dollars in seconds: “That wasn’t me…”

continue

…because the moment a cardholder says “That wasn’t me,” a completely different legal machine wakes up inside the banking system, one that treats your transaction not as a disagreement but as a crime scene, and to survive inside that machine you have to understand exactly how it reconstructs events, who it trusts, and what kind of proof it is willing to accept, which is why we now need to go deep into the anatomy of a fraud chargeback, not the surface-level version merchants see in their dashboards, but the real internal version banks use to decide whether your money lives or dies.

The Anatomy of a Fraud Chargeback

From the issuer’s point of view, a fraud chargeback is not a refund request.

It is an investigation into whether a card was used without permission.

That means the bank starts with three assumptions:

1. The cardholder is telling the truth

2. The merchant cannot see the buyer

3. The network must protect the cardholder

Those assumptions bias every step that follows.

Here is the internal flow.

The cardholder reports a transaction as fraud.

The issuer temporarily credits the cardholder.

The transaction is flagged as unauthorized.

The issuer pushes the dispute to the network.

The network pushes it to the acquirer.

The acquirer pushes it to your processor.

Your processor pushes it to you.

By the time you see it, the system has already decided:

“This is fraud unless proven otherwise.”

You are not trying to prove you are right.
You are trying to overcome a presumption of guilt.

What the Bank Is Really Asking in a Fraud Case

Despite all the language about “fraud,” the bank is actually asking only one question:

Was the cardholder involved in this transaction?

Not:

• Was the product good?

• Was it delivered?

• Was it used?

Only:

• Was the cardholder the one who authorized or participated?

Everything else is noise.

That’s why merchants lose even when they can prove:

• The item was shipped

• The service was delivered

• The user logged in

• The product was consumed

Because none of that answers the identity question.

The Evidence Hierarchy in Fraud Cases

In fraud disputes, banks rank evidence in a strict hierarchy.

At the top:

1. 3-D Secure / Verified by Visa / Mastercard Identity Check

2. OTP / SMS / biometric authentication

3. Strong device and IP matches

4. Account history tied to the cardholder

5. Shipping to the billing address with signature

Everything else is secondary.

Support emails? Weak.
Screenshots? Weak.
Invoices? Weak.

The bank is not asking, “Did someone interact with your business?”

They are asking, “Did the cardholder authenticate?”

Why 3-D Secure Changes Everything

When a transaction uses 3-D Secure, the liability shifts.

That means if the cardholder claims fraud, the bank eats the loss — not you.

That is why banks love it.

That is why high-risk merchants require it.

That is why fraudsters avoid it.

And that is why if you don’t have it, you are exposed.

Without 3-D Secure, you must prove identity yourself.

That is brutally hard.

The Illusion of IP Addresses

Merchants love IP addresses.

Banks don’t.

Why?

Because IPs prove location — not identity.

If the fraudster is in the same city as the cardholder, the IP matches.

If they use a VPN, the IP lies.

Banks know this.

So IPs are supporting evidence — not decisive.

Why Device Fingerprinting Matters More

A device fingerprint tracks:

• Browser

• OS

• Screen size

• Fonts

• Plugins

• Hardware

If that fingerprint appears on multiple successful transactions before the dispute, it strongly suggests the same person made them.

That’s powerful.

But most merchants don’t collect it.

How Fraudsters Use Your Own Systems Against You

Sophisticated fraudsters don’t just steal cards.

They:

• Create accounts

• Use free trials

• Build history

• Make small purchases

• Then hit big

So when they commit fraud, it looks like a loyal customer.

That’s why banks don’t trust account history alone.

They trust authentication.

The Real Reason Digital Merchants Lose More

Physical merchants have:

• Shipping

• Signatures

• Addresses

Digital merchants have:

• Emails

• Logins

• IPs

Those are weaker identity signals.

So fraud chargebacks hit them harder.

This is why SaaS, coaching, and digital products are high risk.

Not because they scam — because they can’t prove identity easily.

The Fatal Mistake: Sending “Proof of Delivery” in a Fraud Case

Merchants often upload:

• Tracking numbers

• Download logs

• Login screenshots

In a fraud case, that’s irrelevant.

The bank is not disputing delivery.

They are disputing authorization.

If you don’t show the cardholder authorized the transaction, you lose.

The Only Way to Win Without 3-D Secure

You must build an identity narrative.

That means showing:

• The same card

• Used on the same device

• From the same IP range

• On the same account

• Over multiple transactions

Before and after the disputed one.

This tells the bank:

“This is not a one-off theft. This is a user.”

That can override the presumption.

But only if you present it correctly.

How Banks Think About Patterns

One transaction is weak.

Five transactions over two months from the same device is strong.

Patterns beat incidents.

That’s why subscriptions are easier to defend than one-time purchases — if you document them.

The Script Banks Expect in Fraud Rebuttals

Winning merchants don’t just upload files.

They explain the pattern.

They say:

“This card was used to create the account on X date.
This device logged in Y times.
This IP range matches the cardholder’s billing region.
The same card was used successfully on Z dates without dispute.
This shows cardholder involvement.”

That language is what issuers look for.

Not emotional pleas.

How Friendly Fraud Hides Inside Fraud Codes

Here’s the ugly truth:

Most fraud chargebacks are not real fraud.

They are:

• Spouses not recognizing charges

• People forgetting subscriptions

• People wanting refunds

• People clicking the wrong option

But once the fraud code is assigned, the system doesn’t care.

You must fight it as if it were real fraud.

That is why understanding this process matters so much.

When You Should Not Fight a Fraud Chargeback

If you have:

• No authentication

• No history

• No device data

• No pattern

Fighting may be pointless.

Sometimes eating the loss protects your account.

High-level merchants know when to let one go.

Low-level merchants fight everything and get shut down.

Fraud Is Not About Truth — It’s About Proof

That is the lesson.

You can be 100% right and still lose.

Because the system doesn’t know truth.

It knows data.

And now that you understand how fraud chargebacks really work, we can move to the second category — no authorization — which looks similar on the surface but is governed by a completely different set of rules, and is where most merchants accidentally sabotage themselves by sending the wrong kind of evidence, because while fraud is about identity, no authorization is about agreement, and that subtle difference determines whether you keep your money or not, which is exactly what we’re going to dissect next by walking through how no-authorization disputes are created, how banks evaluate them, and how you can turn what looks like a lost cause into a high-probability win if you know how to show that the cardholder actually said “yes,” even if they’re now pretending they didn’t, and that is where many merchants finally start winning chargebacks for the first time, which is what we’ll break down as we continue…

…by stepping into the second chargeback universe — no authorization — where the question is no longer “who are you?” but “what did you agree to?”, and this shift changes everything about how banks judge your case, because in this courtroom the cardholder is no longer saying a thief used their card, they are saying they themselves did not give permission for the charge, which might sound like the same thing, but in the eyes of the network it is a fundamentally different accusation, one that opens the door to contracts, terms, checkout flows, and consent records, which means if you know how to present them, this is where many merchants can finally start to win.

What a No Authorization Chargeback Really Means

When a cardholder files a no-authorization dispute, they are telling the bank:

“I didn’t approve this charge.”

That could mean:

• They forgot

• They didn’t read

• Someone else in their household did it

• They canceled and got charged

• A free trial ended

• A subscription renewed

Unlike fraud, the bank is not assuming a criminal was involved.

They are assuming a billing mistake or misunderstanding.

That means the standard of proof is lower.

You do not have to prove identity.

You have to prove consent.

The Question the Bank Is Asking

In a no-authorization case, the bank wants to know:

Did the cardholder agree to be charged this amount, at this time, under these conditions?

If you can show yes, you win.

If you can’t, you lose.

It’s that simple.

The Most Powerful Evidence in No Authorization Cases

Banks care about:

• Checkout page screenshots

• Pricing display

• Terms and conditions

• Subscription or trial disclosure

• Cancellation policy

• “I agree” checkboxes

• Email receipts

• Account creation

All of these show the cardholder had a chance to understand what would happen.

They don’t care much about:

• IP addresses

• Devices

• Shipping

• Usage

Because those don’t prove consent.

Why Merchants Lose These When They Should Win

Most merchants submit fraud-style evidence.

They show:

• Login logs

• Download activity

• IPs

The bank ignores it.

They wanted to see:

Where did the cardholder agree to pay?

If that’s missing, you lose.

Even if the customer used the product.

The Power of the Checkout Screenshot

One image of your checkout page can beat 50 pages of logs.

Why?

Because it shows:

• Price

• Currency

• Billing frequency

• Terms

• Refund policy

• What the customer saw before clicking “Pay”

That is the heart of consent.

How Subscriptions Live or Die Here

Most no-authorization disputes come from subscriptions.

The cardholder says:
“I canceled”
or
“I didn’t know it would renew.”

The bank asks:

Was that disclosed?

If your checkout showed:

• “$29 per month after trial”

• “Renews automatically”

• “Cancel anytime before X”

And you can prove the customer saw it, you win.

If you didn’t disclose it clearly, you lose.

Why Email Receipts Matter

Email receipts show:

• Date

• Amount

• Merchant name

• What was purchased

They prove the customer was notified.

Banks see that as implicit consent.

That’s why merchants who send clear receipts win more.

The Silent Killer: Bad Billing Descriptors

If your charge shows up as:

“XYZ LLC”

But your website is:

“SuperGrowth Marketing”

The cardholder clicks:
“I don’t recognize this merchant.”

Now it’s no authorization.

Even though they bought from you.

This alone causes millions of disputes.

How to Win No Authorization Disputes Like a Pro

Your rebuttal must tell a story of consent.

It should show:

1. The checkout page

2. The pricing

3. The agreement

4. The receipt

5. The policy

In that order.

You are not arguing with the customer.

You are educating the bank.

Why Friendly Fraud Loves No Authorization

Many customers choose no authorization because it sounds softer than fraud.

They think:
“I’m not saying someone stole my card, I’m just saying I didn’t authorize it.”

To the bank, that still means:

“Merchant must prove consent.”

That’s why this category is so important.

The Difference Between “Didn’t Authorize” and “Didn’t Like”

If the customer didn’t like the product, that is not a valid no-authorization claim.

But banks don’t judge satisfaction.

They judge agreement.

So you must show the agreement was real.

When You Should Always Fight

No authorization disputes are some of the most winnable if you have:

• A clean checkout

• Clear disclosures

• Good receipts

This is where many merchants get their highest win rates.

And Now We Come to the Most Dangerous One of All

Friendly fraud.

The category that doesn’t officially exist.

The one that destroys businesses quietly.

The one that hides inside fraud and no-authorization codes.

This is where customers weaponize the system against you.

And this is where most U.S. merchants are bleeding money without even realizing why, because when friendly fraud explodes, your dispute rate goes up, your risk profile goes up, your fees go up, and eventually your account disappears, even though most of your customers were “happy,” which is the cruel irony of the whole system, and that is exactly what we are going to break down next by exposing how friendly fraud really works, how customers learn to do it, how banks encourage it, and how you can defend yourself against it by turning behavior into evidence in a way the networks actually respect, which is where the real art of chargeback defense lives, and that’s what we’re diving into next as we continue…
