Credit and Debit Card Checker: A Free App to Validate Card Numbers
Credit and Debit Card Checker is a free Android app developed by Ven Tech Apps that allows users to check the validity of their credit and debit card numbers. The app uses an updated database to check the existence of a Bank Identification Number (BIN) and supports all major credit and debit card brands, including VISA, Mastercard, American Express, Diner's Club and BankCard. It also specifies the type of card and the country and issue bank from the popular BIN databases.
The algorithm used to validate the card numbers is the Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm. It's a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers. The app is designed to process the card numbers in minimum time, and the user can get the result in a fraction of time. The app also features a QR code generator, an ATM locator, a credit card reader, and a bank balance checker.
