Reason Code F31: EMV Lost/Stolen/Non-Received

A transaction was made using an actual credit card, but the cardholder claims they didn’t participate in the transaction since their card was stolen, lost, or never received. The merchant didn’t detect the fraud because they manually keyed the transaction or used a terminal that wasn’t PIN and chip-enabled.

• Criminal fraud was committed.
• The merchant didn’t get a manual imprint of the key-entered transaction.
• The merchant didn’t identify a card-not-present transaction.
• The merchant failed to ensure the card was swiped, or its chip read.

The merchant should:

• Only use EMV-compliant terminals.
• Obtain proper validation, including PINs or imprints.
• Take imprints of card-present transactions.
• Train staff on the right procedures for handling terminals.
• Make proper differentiation between card-present and card-not-present transactions when clearing mail, phone, or internet orders.

The F31 reason code doesn’t apply to digital wallet payments, contact-less transactions, or charges that are part of the No PIN program.
