Card Testing Indicators: A Comprehensive Guide

What are Card Testing Indicators?

Card testing indicators are crucial tools for verifying the legitimacy of a credit card number. They include the CVV, expiration date, and cardholder name. These indicators help ensure that a card is not stolen or counterfeit.

  • Cardholder Name: The name printed on the card.
