If you havent already figured it out, then our test card number generator and validator uses Luhn algorithm / formula a.k.a the mod 10 check to generate and validate dummy card numbers. You can modify to add more Credit Card types. Any Software developer or your payment gateway developer can generate and validate dummy credit card numbers here and use it for integration testing. Currently, this PL/SQL function supports three kinds of the Credit Cards which are Visa, MasterCard, and American Express. The following function takes an argument as Credit Card number and then validates the number using Luhn algorithm and returns its type.

Luhn checksum validation library for Java. The value of this inside the callback is set to the input element to which the validator was attached: $('#cc_number').validateCreditCard(function(result) A simple credit card validation Java library with no dependencies. Validates Credit Card Number and displays information based on it. In browsers that don’t support input event, the callback will be called only when the user releases a key on their keyboard ( keyup event). That means, in most browsers, it will run the callback every time the value changes: regardless of how the change was initiated (keystroke, paste, undo, redo, etc). ![]() The plugin uses input event with a fallback to keyup. '\nLength validation: ' result.length_valid If the callback parameter is specified, the plugin will call it every time the field’s value changes and pass it the result object: $('#cc_number').validateCreditCard(function(result)Īlert('CC type: ' result.card_type.name ![]()
