Credit Card Number Validator is a free software that verifies the legitimacy of credit card numbers without the need for an online connection. This eliminates the risk of exposing sensitive information while allowing easy validation on your PC.
The Credit Card Number Validator employs the LUHN formula, also known as MOD 10, which checks the validation of the primary account number. This formula ensures that the number combination is correct and accurate, but it does not validate the card itself, so it is essential to keep this in mind.
With the Credit Card Number Validator, users can be notified of the credit or debit card type by simply inputting the first digits of the card number. However, it only verifies if the credit or debit card checksum is valid and not the credit or debit card account itself. In case of account validation, sufficient software that can access credit and debit card networks is necessary. This software will usually submit authorization requests for the card account.
The Credit Card Number Validator offers several features that are beneficial in validating credit and debit card numbers. It uses the LUHN10 (MOD10) checksum algorithm, first digit verification, automatically determining the type of credit card, and validates any Visa, MasterCard, AMEX, Discover, or Diners Club credit card numbers.
Overall, the Credit Card Number Validator is a useful tool for anybody who handles credit or debit card transactions. It's free and secure, offering a local and reliable way for users to check the validity of card numbers.
