Single-Use Card

A Single-Use Card (SUC) is a type of virtual payment card, often a derivative of a credit or debit card, that is programmatically generated for a single transaction and automatically expires or becomes invalid immediately after that transaction is completed, significantly enhancing payment security. These cards, also known as disposable or one-time-use cards, function by masking the user's actual primary account number, thereby preventing merchants, even if compromised, from storing or reusing sensitive payment credentials for subsequent unauthorized charges.
