Yes, (ThisYear + 11) is mathematically equivalent to (((ThisYear - BaseYear) + 12) + (BaseYear - 1)). I didn't think of simplifying - thanks.
Ah... another fly in the ointment. I was not aware of the PCI regulations. I will read it and inform the client. Currently, the only thing that is being saved by the web app is the:
1. last for digits of the credit card number
2. the card holder name
3. expiration date.
The web app does not do any credit card payment processing, that is done through some third party merchant service the client has been using since before the web app was developed. The user just wants to manually enter and store the above credit card info into the web app database for future reference.
I'm reading the PCI docs but I haven't found what regulations, restrictions or procedures that the web app or database has to follow yet regarding this issue. Do you know where they are?
