Category FraudBy Payment Defender Editorial TeamUpdated July 17, 2026Last reviewed July 17, 2026
What American Express Reason Code F10 Means
American Express reason code F10 applies when a charge is disputed as fraudulent and the merchant cannot provide a valid imprint of the Card. The dispute centers on the absence of a required Card imprint for a card-present transaction.
Why This Chargeback Happens
This dispute commonly occurs in card-present environments when the Card was not properly captured electronically or by manual imprint, when a transaction was keyed without card verification, or when supporting records are missing.
What the Cardholder or Issuer Is Claiming
American Express is asserting that the disputed charge lacks a valid imprint of the Card to support the transaction.
What Merchants Should Review
Review the transaction records for evidence of a Card imprint or electronic read. Confirm whether the Card was present, how it was captured, and whether supporting documentation exists for the charge.
Recommended Chargeback Evidence
- Electronic Card-read data or manual imprint records
- Signed receipt tied to the transaction
- Point-of-sale logs showing how the Card was captured
- Any additional evidence the Card was present and authorized
How to Prevent Similar Disputes
Merchants may reduce these disputes by capturing Card data properly at the point of sale, retaining imprints or electronic reads, and avoiding manual entry without verification. Consistent record-keeping helps support card-present charges.
