Don't Encrypt, Don't Store

If you go with a credit card processor like Verisign or Authorize.Net, you can just reference a previous authorization and tell them to re-bill the customer.

The process works like this:

  1. Collect payment information.
  2. Authorize the payment through your gateway (Verisign,, etc).
  3. Get your authorization number.
  4. Store the authorization number.
  5. (Time passes, then it's time to re-bill)
  6. "Hey credit card company - charge the customer referenced by authorization # XYZ in the amount of $Y.YY"
