Magento – Automatically Determine Credit Card Type

magento-1.9payment-methods

I was wondering if there is a way to automatically determine the credit card type for magento credit cards forms instead of having the customer manually pick it.

Thanks in advanced

There's a great post about this on stackoverflow. You can check the answers here: https://stackoverflow.com/questions/72768/how-do-you-detect-credit-card-type-based-on-number.

The two post important excerpts:

Visa: ^4[0-9]{6,}$ Visa card numbers start with a 4.

MasterCard: ^5[1-5][0-9]{5,}$ MasterCard numbers start with the numbers 51 through 55, but this will only detect MasterCard credit cards; there are other cards issued using the MasterCard system that do not fall into this IIN range.

American Express: ^3[47][0-9]{5,}$ American Express card numbers start with 34 or 37.

Diners Club: ^3(?:0[0-5]|[68][0-9])[0-9]{4,}$ Diners Club card numbers begin with 300 through 305, 36 or 38. There are Diners Club cards that begin with 5 and have 16 digits. These are a joint venture between Diners Club and MasterCard, and should be processed like a MasterCard.

Discover: ^6(?:011|5[0-9]{2})[0-9]{3,}$ Discover card numbers begin with 6011 or 65.

JCB: ^(?:2131|1800|35[0-9]{3})[0-9]{3,}$ JCB cards begin with 2131, 1800 or 35.

And a full class actually
