nice tool to check if creditcard is valid

you can use it in your own way :winkwink:

Looks like a phishing site to me.
Why would anybody give their CC details there?

Yeah for real.. I'm sure lots of people fall for that though

Thx, but I am not going to do any tests. :pimp

nope, works different. They do the charging for thousands of websites, here you can check your last transaction with them. Thats why that link can be very handy.

here is an example paylink

The first four digits of a CC are simply the bank identifiers. If you have a user's laster 12 digits, and GeoIP their country, run that against a list of card-issuing banks in that country (normally going to be 10 or less) - bam!

If you're really looking to verify cc#s, check out http://en.wikipedia.org/wiki/Luhn_algorithm

Note for advanced players: the linked PHP version on that article has some bugs in it.

i know the algorithm for that, but here you can check if the card has been used on a pornsite so you really know its valid ( its just an extra chck )

Sure sounds..... ummm ya pass..

Is it legal or ok with your merchant for you to be typing customer's card numbers into another site that isn't theirs?
