A card chargeback is a dispute by the cardholder of a card transaction to his/her bank, leading to the cancellation of the original transaction and the re-credit of the cardholder.
A card chargeback can have several reasons (detailed in the comment section of the chargeback transaction - more info in the dedicated topic), the most common being: fraudulent transaction, transaction not recognized, services not provided or merchandise not received, duplicate payment.
A card transaction can be charged back up to 13 months following the date of the original transaction.
A card chargeback has two main effects:
• For the cardholder - total or partial re-credit of the original transaction amount
• For the merchant/you - debit of the chargeback amount on the payment account on which the original transaction has been credited and perception of the associated chargeback fees on your merchant payment account (SC)
You are 100% liable for card chargebacks as well as associated fees, as stated in your contract.
