Disable stolen bank cards with OTU QR code (+1, -2) [vote for, against]

Basically have two QR code that is printed into a card/sticker etc... It has a sticky cover on top of it so people cannot snoop on the code before usage.

Upon theft/loss of card, you simply grab the nearest phone and have them scan either one of the QR code, (one is a url, and the other one is an SMS). It will then send a one time password to disable the card.

This process is much faster than calling the bank.
