About This Tool

This tool checks if a credit card number is potentially valid using the Luhn algorithm and attempts to identify the card type. It can also generate sample credit card numbers for various issuers.

Validation does NOT verify if the card is real, has funds, or is active. It only performs mathematical checks. Generated numbers are for testing/development and are not real accounts.
