A “fake credit card number” refers to a sequence of digits not associated with a legitimate credit card account. For instance, a randomly generated string like “4242 4242 4242 4242” would be considered a fake credit card number.
Fake credit card numbers are significant as they enable testing and development of e-commerce systems without requiring real payment information. Their use has grown alongside the rise of online shopping and digital payments. Historically, the development of the Payment Card Industry Data Security Standard (PCI DSS) led to increased adoption of fake credit card numbers as a secure way to handle payment data.
