Amex reason code F30
Amex F30: EMV Counterfeit
What the cardholder is claiming
A counterfeit card was used at your terminal, and because the transaction was not processed as a chip read, the counterfeit fraud liability shifted from Amex to you.
The evidence that actually wins
Bank analysts skim responses in minutes against a checklist for this exact code. Lead with the strongest fact; never make them dig.
- ✓Authorization data showing the transaction was actually chip-read, including the POS entry mode and chip cryptogram
- ✓Terminal certification records proving your device was EMV-enabled and functioning at the time
- ✓Proof the transaction was actually card-not-present and the code was misapplied
- ✓Records showing chip fallback was triggered by the card itself, with the fallback properly indicated in the authorization message
The honest read
This is a liability-shift code, so the question is not whether fraud occurred but who eats it, and the answer was decided by how your terminal read the card. If a counterfeit card was swiped or keyed on a non-chip terminal, the loss is yours by rule and fighting wastes the response fee. The only arguments that land are technical: the transaction was really chip-read, or it was really card-not-present and miscoded. Pull the actual authorization message before deciding, because your processor's records settle this in five minutes.
Nobody can promise you a win; the cardholder's bank decides. What you control is submitting the strongest complete case your records support, on time. Our plain-language guarantees say exactly what that means.
