Zend Credit Card - Validation and Card Type

Ryan Johnston · 2010-04-26 22:45:51

Hi,

So I know I can use Zend_Validate to Validate a Credit Card number against a list of "accepted" credit card types.

I was wondering if there is a similar feature / way to determine what type of credit card it is based on credit card number?

Cheers,
Ryan

Hi Ryan,

you could encapsulate these business rules into a Zend Web Service and be good to go:

Hope that helps,

Hey Jon,

Yeah I have it detecting now however there is a few problems with it's success based on what the banks have been doing.

http://en.wikipedia.org/wiki/Bank_card_number

Eg: Diners Club US and Mastercard eventually share the exact same prefix / length as "On November 8, 2004, MasterCard and Diner's Club formed an alliance." and differ based on region.

Now we do GeoIP the user but that's not 100% either.

I'm thinking the only solution will be when multiple card types are found to populate a dropdown box and ask the user to be more specific.

Frustrating haha, if only card prefix with length were independent. If Diners Club US had a different length to Mastercard then it would be easy but nope >.<

Well luckily we're not supporting cards like Diners Club US so everything works well

Cheers for that reference Jon

I was also thinking... I did some work with Authorize.net at one point and I'm not sure but they might hav had a call in their API to return the card type...

Yeah unfortunately the payment provider we are going with only takes credit card info / type etc to make a payment, no APIs to determine card type etc

Hi
The details are all on Wikipedia: wikipedia.org/wiki/Credit_card_numbers
