Fraud
The cardholder claims their chip card was counterfeited, and the merchant processed a transaction with the counterfeit card on a non-EMV-compliant POS terminal that couldn’t detect the fraud. As a result, they claim the transaction was unauthorized.
The card issuer gets 30 extra days to file a chargeback if they submitted a retrieval request which was completed after the 120 days.
