What is a Card Test Sample?

A card test sample is a method used to verify the authenticity and validity of a credit card. It typically includes the card number, expiration date, and CVV (Card Verification Value) for testing purposes.

Why Test Card Samples?

Testing card samples is crucial for ensuring the integrity of transactions and preventing fraud. It helps to identify any discrepancies in card information before processing payments.
