Validating credit card
Without a valid owner name, an expiration date and a valid CVV code, they can't be used for real transactions.
Note that the algorithm used here is freely available across the web even
Assume that you are using two separated fields for expiration date.
The first field asks user to fill the expiration month, and the second one is for the expiration year.
Credit Card Validator provides validation utilities for credit card data inputs.
It is designed as a Common JS module for use in Node.js, io.js, or the browser.
To validate, type the Credit Card or Debit Card Number in the specified field below.
Make sure that the Credit Card or Debit Card Number follows the proper format.
My SQL Functions Functions "ccc" and "ccd" (credit-card-check and credit-card-digit) Note that the "ccc" function has an additional check where if the calculated sum is 0, the returned result will always be FALSE, so an all zero CC number will never validate as being correct (under normal behaviour, it would validate correctly).
Credit Card Validator will also provide a determined card type (using credit-card-type).
