The merchant processed a transaction using a counterfeit card, and the cardholder denied participating in the transaction. The merchant didn’t flag the counterfeit card because they used a POS system that’s not chip and PIN enabled, or they manually keyed the transaction.
Cause
The POS wasn’t chip-enabled, or the merchant manually keyed the transaction.
The merchant didn’t fully transmit chip data.
