This does make the assumption that the Credit Card number is unencrypted (If stored in the Database) and as the PCI/DSS regulations strictly forbids this, I would be very careful about the use of using any form of un-encrypted credit cards. This will cause you major headaches with PCI DSS - also in practice Credit Card encryption has to be performed to the Payment Card Industry standard (so you can't generally use your own encryption methods)

Reference: Requirements 3 and 4 of the PCI DSS version 1.2

this works for everything but american express ... in any case my impression was that PCI DSS allows encrypted storage untill it is processed, once processed you must purge it asap.

I was really expecting to see a set-based approach to this formula.
