"Even better we were able to get rid of the 'select your card type' field since that was detected by Luhn." FYI: Card Type is not determined by Luhn algorithms, but rather (broad brush strokes, see http://en.wikipedia.org/wiki/Bank_card_number#Issuer_Identif... for more detail): 3 - American Express
4 - Visa
5 - Mastercard / Diners
6 - Discover |
