Intro:

CreditCardChecker is an application that will verify the checksum 
of credit card numbers for various credit cards. It works on most 
cards that I tried.  It was made to give everyone another safety tool 
to fight fraud or simply to check out if the card your using has
a checksum.

This OpenStep application is based on the cc_cksum.c program 
that appeared in the 2600 magazine. (Which issue? I don't 
know...)

All credit card numbers have a checksum number which permits 
you to verify if the number actually makes sense. Meaning if 
the number that you have is a possible number. Even if the 
number passes the checksum test it does not mean it's an 
actual valid number. So if you can, please verify with the 
proper authorities for the validity of the number. If you cannot, 
hopefully this will help you a bit, but don't count on it...

This program is distributed in the hope that it will be useful, 
but without any warranty; without even the implied warranty 
of merchantability or fitness for a particular purpose.
