Credit Card Number Validator is a free Android app developed by Vijay Mehra that checks the validity of credit card and debit card numbers. This app supports all major credit card and debit card brands such as VISA, MasterCard, American Express, Diner's Club, and BankCard. It also has an updated database for the latest information about the credit card bin checker. The app requires an internet connection to get the latest information about the bin.

The Credit Card Validator app is designed to check the existence of a Bank Identification Number (BIN) based on an updated database. There are currently more than 400,000 unique BINs in the database. The app also allows you to check your credit card validator, number, and specify the type of the card. The algorithm used to process the Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm, is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, National Provider Identifier numbers in US and Canadian Social Insurance Numbers.
