I haven't been able to find any programs to verify all 4 types of the
major credit cards so I decided to write this one. It uses the Modulo-10
check digit method. It will verify MC,Visa,Amex, and Discover card numbers.
It will also verify other types of credit cards but since I'm not sure of the
format it will just come up with a message like "Number sequence verified
but unknown type." If someone knows the format for other cards please contact
me. I think Canadian Social Security numbers also follow this format,
so if you enter on of those you will also get the unknown type message.
This program is excellent to verify those account numbers on CBI or TRW!
Since some bank loan accounts are also between 13-16 digits long and begin
with '5' you cannot tell the difference between them unless you test them
with a program like this.
If you have any ideas for other programs get them to me and I will work on
them. Also if you know of any groups that are looking for someone that knows
how to program get my board number to them!.
This is a TìC (The-Inner-Circle) utility release.
