That's interesting. I feel like the way to really get this business off the ground would be for someone like 1password or Chrome to replace the credit card number they store with one they own, and then when you use it to fill in a form with your credit card information, the merchant charges them and they charge you a 1% service fee or something. Overnight, you are taking 1% of all Internet shopping revenue.

The ethics are, of course, terrible. I made myself a little sad just writing this!
