Описание скрипта Credit Card Validation Solution

The Credit Card Validation Solution is an open source script that ensures the credit card information is keyed in correctly. The Credit Card Validation Solution checks that the card number length is correct, the first four digits are within accepted ranges, the number passes the Mod 10 / Luhn checksum algorithm and that you accept the given type of card. Expiration date validation is optional. Also it tells you which kind of card is being used based on the number.
Error message text is internationalized. Current translations include English, French (Français), German (Deutsche) and Spanish (Español). Others can be easily added.
