     This handy little utility will generate valid credit card numbers for Visa, Mastercard, American Express and Discover. Like other programs here it uses the LUHN formula for verification. The random generator uses 11 banks for Visa, 4 for american express, 1 for mastercard and 1 for discover. (More can be added. check comments in Validate.frm) This program was not written to defraud but for education purposes only, to show how simple the LUHN formula is. PLEASE USE IT AS IT IS INTENDED -- EDUCATIONAL PURPOSES. After the random number has been selected it then verifies it, and will continue to evaluate random numbers until it has selected a valid number.(Takes about 1 to 2 seconds.) The validate option allows you to input a number and verify it as either Valid or Invalid. Don't forget to rate this program. --Enjoy

  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
