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.Don't let greediness blur your vision | You gotta let some shit slide

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

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