- baddox 8y agoWouldn't they need the plaintext credit card number to, well, charge the credit card? Maybe not, if they're using a third-party credit card processor that stores the credit card number keyed by an account ID, but I doubt Uber is using a separate processor.

- waterhouse 8y agoSurely names aren't a unique identifier? "John Smith" et al. Would they keep around other information and use that?
