A fake credit card number generator is an online tool to generate random, valid-looking credit card numbers. These numbers are often used for testing and validation purposes. The primary use of these generators comes in e-commerce applications and payment gateways. The fake credit card numbers look like actual credit cards but are not linked to financial institutions.
Using an actual credit card for testing can cause security concerns and accidentally place an order, resulting in losing money. Most credit card generators use Luhn’s technique. Developed by Hans Peter Luhn, an engineer at IBM, in 1954, this algorithm is widely used in the financial industry to check the validity of credit card numbers and other similar numbers.
