It's not necessary. In fact, at some point I hope to write up a larger piece on it.
The only two NECESSARY pieces of data are the CC number and the expiration date. ZIP code drops some of the risk, and, accordingly, drops a fraction off the percent you're charged by the processor.
On the web app we're about to launch, we only have the number and the expiration date. I'm hoping to get my act together to do some A/B tests, but we're going into it assuming that we'll do better with fewer fields to fill out.
- dangrossman 16y agoI could be wrong, but I don't think the expiration date is necessary either. You have to send one to your gateway, but I don't think it's actually used for anything. You can keep charging cards that expired and have been reissued with the same number; I suspect if you send a valid card number with any future expiration date, it's going to work too.
- genieyclo 16y agoYep, if I recall correctly, expiration dates are just there to get people to get new cards for accounts because the magnetic strip on the plastic fades after a number of years.
