High Density Credit Card

(Me during Intermag 1996 finding out how Boeing aeroplanes are built near Seattle, WA.)

This aim of this project is to get about 10KBytes onto a normal plasic credit card. The purpose of this is to put biometric information onto the magnetic strip, so that it does not have to be printed on the surface of the card.

Suitable biometrics are pictures, the signature, and cryptographic public key of the credit card holder and bank.
