VbzCart/tables/cust cards

About

• Purpose: for recording the information necessary to get paid by credit/debit cards
• Fields:
  • if WhenInvalid is NOT NULL, then this number has been permanently destroyed/deactivated; any use of this number is therefore suspicious. Date is the earliest date it was known to be bad. Overrides isActive.
  • Address may be no longer necessary, except for handling legacy data
• History:
  • 2009-07-09 moved to separate wiki page; no design changes
  • 2009-10-07
    • removed CryptAddr, renamed CryptCard as Encrypted
    • added ID_Name
• Future:
  • Address should go away, probably without any need to verify that ID_Addr agrees with it
  • Records with OwnerName need to have ID_Name set, and then the OwnerName field can be removed
  • isActive should eventually go away; probably the best thing is to wait until all isActive=FALSE cards have expired (end of Feb 2010), then set WhenInvalid to each card's expiry date.
