Ragan is totally right about this being wrong and needing to be fixed.
However, the idea that websites should use the bank's payment gateway for validation is misguided. Your fee's will be increased (or your account will be suspended) on many payment gateways if you do this.
- raganwald 17y agoI think it depends on what you're validating. If you are trying to validate a name, you had better get it right! For example, my Visa still says Reginald Braithwaite-Lee, but I might register on your site as Reg Braithwaite. Did I misspell my name or is that what's on my Visa? Is the hyphen a typo? OTOH, some things seem to be more certain, like rules about check sums. I like the approach suggested by many folks: Use JS to validate on the client, and put up a "Are you really, really sure?" message for things that seem unusual like a single name or a funny character.
