Does anyone know how to generate a unique card number based on a
previously existing number? I'm trying to create a 16 digit Check
number by only given the first 15 digits. I've been to this site:
http://www.beachnet.com/~hstiles/cardtype.html to use the Excel spread
sheet file and it doesn't give me the info I need. Any help is
welcomed.
Thanks,
John
