    Credit Card Validation - Check Digits

    Report bad ads?

    A'salaam alaykum ,

    Hope this article will be of help to some of the brothers who are in software industry


    This article outlines procedures and algorithms for Verifying the accuracy and validity of credit card numbers. Most credit card numbers are encoded with a "Check Digit". A check digit is a digit added to a number (either at the end or the beginning) that validates the authenticity of the number. A simple algorithm is applied to the other digits of the number which yields the check digit. By running the algorithm, and comparing the check digit you get from the algorithm with the check digit encoded with the credit card number, you can verify that you have correctly read all of the digits and that they make a valid combination.



    Check out the article:

    Allah alone is sufficient for me.

    I am a Muslim I say, "laa ilaaha illallaah Muhammadur-Rasoolullaah." There is none worthy of worship except Allaah, Muhummad is the Messenger of Allaah.

    Although, one the numberts are generated you'd need the correct expiry date, issue number (if switch), last three numbers on the back (cvv2 code) and sometimes correct billing address before it works.... not that I've tried.
