This sort of reminds me of public key cryptography. I generally really like the idea. I've always felt really uneasy about credit cards, the fact that all I have to do is enter the same numbers to every single website I purchase from. The programmer in me tells me "this just can't be secure", and the only hope I have that my card number is never stolen is, well, hope. |
