Visa Number Verification

[RoyDaly]

I am looking for the algorithm for checking for valid Visa/Mastercard numbers. The FMP script would also be helpfull.

Thanks

I recall reading a pdf on this. Unfortunately I do not recall if I found it at FileMaker or another FMP support site such as FileMaker Today. However, I hope this puts you on the right path.

Peace
