The process where a transaction is approved by the issuer of a credit card, supported by delivery of a sales validation to the merchant.

The customer to whom a credit card is issued and any other individual authorized to use the card.

Charge Back

A charge disputed by the credit card holder, resulting in chargeback fees against the merchant. If the cardholder is successful in his dispute, the disputed funds are debited from the merchant account. Funds are often taken out during the period that the dispute remains unresolved, pending its resolution.

Credit card

The plastic card bearing an account number assigned to a cardholder. Credit cards are issued with a set credit limit and expiry date.
