FraudAmex F30 — EMV Counterfeit Fraud: What It Is and How to Respond
Act immediately. Amex gives you only 20 calendar days to respond — 10 fewer than Visa. By the time you receive the notification, you may have fewer than 2 weeks. Treat every F30 dispute as a day-1 priority.
F30 is the Amex equivalent of Visa 10.1. A counterfeit chip card was used at a merchant terminal that wasn't EMV-enabled, so the chip was not read. Because the merchant couldn't verify the chip, liability for the counterfeit fraud shifts to the merchant. EMV chip cards are significantly harder to counterfeit than magnetic stripe cards — when a terminal can't read the chip, it can't detect the counterfeit.
The only viable defence against F30 is proof that your terminal was EMV-capable and that the chip was successfully read for this transaction. If your terminal processed the card via magnetic stripe instead of chip — even if the card had a chip — the EMV liability shift applies and you bear the fraud loss.
Can you win this dispute?
Fight this dispute if...
- ✓Your terminal was EMV-capable and chip was successfully read — provide terminal configuration records and transaction receipt showing chip authorization
Accept this chargeback if...
- ✗Your terminal is not EMV-capable and the transaction was processed via magnetic stripe fallback on a chip card
Evidence checklist
- ✅ Required
Terminal configuration log showing EMV capability was active: A report from your payment processor confirming your terminal model, software version, and that the EMV application was enabled at the time of the transaction.
- ✅ Required
Transaction receipt showing chip (not swipe) authorization: The receipt must indicate the card was read via chip — look for “ICC” or “Chip” indicators on the receipt, as opposed to “Swipe” or “MSR”.
- ⭐ Strongly recommended
Processor logs showing chip data was captured: Transaction-level logs from your processor showing the EMV cryptogram (ARQC/TC) was present, confirming chip data was exchanged.
The ongoing cost of non-EMV terminals
Non-EMV terminals create ongoing F30 liability for every counterfeit card transaction. The cost of upgrading to EMV hardware is trivially small compared to the chargeback liability exposure. If you are receiving F30 chargebacks, upgrading your terminals is the only permanent solution.
Frequently asked questions
What is an Amex F30 chargeback?
Amex F30 is filed when a counterfeit chip card was used at a merchant terminal that was not EMV-enabled. Because the terminal could not read the chip, it could not detect the counterfeit card data. Under EMV liability shift rules, responsibility for the fraud moves to the merchant whose terminal was not chip-capable. F30 is the Amex equivalent of Visa 10.1.
How does the EMV liability shift work?
EMV liability shift is a card network policy: if a chip card is used at a chip-capable terminal, liability for counterfeit fraud rests with the card issuer. If the chip card is used at a non-chip terminal (or processed via magnetic stripe fallback), liability shifts to the merchant. This creates a financial incentive for merchants to upgrade to EMV terminals. If your terminal read the chip, you're protected. If it didn't, you bear the loss.
How do I prove my terminal was EMV-enabled?
The strongest evidence is a terminal configuration log from your payment processor showing the EMV application was active, combined with a transaction receipt that explicitly shows chip authorization (not swipe). Most processor portals can generate terminal configuration reports. Your processor support team can also provide a letter confirming EMV capability for your terminal model and software version at the time of the transaction.
How is F30 different from F31?
F30 is about counterfeit cards — a fraudster created a copy of a real chip card and used it at your terminal. F31 is about lost or stolen cards — the actual physical card belonging to the cardholder was used by someone who found or stole it. Both result in the same merchant liability when the terminal is not EMV-enabled, but the root cause differs. Counterfeit fraud (F30) is particularly associated with magnetic stripe skimming.
