Thus, the exception. Yeah, in the encryption, I had to decide what to make different lengths. Personally, I don't think you can get much from knowing what type of card someone has. I know anyone else in Louisville w/ a 5/3 Bank account will have a Mastercard debit/check card, but I can't really do anything with that I don't have a way to restrict what someone puts in that textfield, so I didn't bother mashing it up to some custom string... so yeah, encryption on the card type field is fairly worthless as is.
