- Purpose: Charges to customer bank cards
- Batches are needed for batch-mode card processing. This was useful when credit cards were debited using PTC, which dialed in the charges using a modem (and hence you wanted to do as much offline as possible), but it's not necessary for PayPal. Will migrate later if it seems useful. Non-batch-mode charges can leave ID_Batch set to NULL.
- I've decided that the field Resolved in the MS Access version should be a separate table listing unresolved charge records; this shouldn't be something that needs to happen when code is working properly.
- CardSafe: same as in Template:VbzCart
- AmtSold and AmtShip are necessary for PayPal Virtual Terminal, which wants to know these amounts separately. Presumably other card processing systems may also want this information.
- AVSAuthChar: it's not clear whether any software besides PTC returns this code. It's also not clear what it means. Only Visa cards ever seem to return this code.
- WhenDecided and isAccepted was WhenAuthorized and WhenRefused in Access
- WhenHeldUp is specifically for old orders where the data which would complete the charge record is missing, and I don't want to fill it in with bogus data just to get it out of the queue. I can imagine that it might be useful for suspending charges due to technical difficulties, but I can't think of a scenario in which some other solution wouldn't be more appropriate. Still: set the timestamp in this field (and make a note!) if you need to pull a charge out of the queue without completing it.
- To view only charges which need further processing, filter for: <mysql>(WhenDecided IS NULL) AND ((WhenXmitted IS NULL) OR isSuccess) AND (WhenVoided IS NULL) AND (WhenHeldUp IS NULL)</mysql>
- 2009-07-09 moved to separate wiki page; no design changes
- 2013-08-15 modifying to meet customer security requirements
- adding "Encrypted" field for now just in case someone decides to break in before I've fully implemented security
- 2013-08-23 New fields to handle encryption properly: CardCrypt,CardSafe; Encrypted is now DEPRECATED
- 2013-09-01 Decided it's silly to duplicate the card information here, especially if we have to encrypt it.
- It's enough to point back to the proper card record in cust_cards and keep only the "safe" info here.
- The "safe" info can be formatted to be searchable without needing to be rigorously parsable.
- Removing CardCrypt, CardNumExp, CardBillAddr, and of course Encrypted
