The Onion Card, created by James Auger and Jimmy Loizeau, is a card that through a bar code connects to a data storage place of personal information, so in a sense is kind of an identification card. The card would allow users to “peel” out certain parts of a bar code containing specific information ( i.e. phone number, address) that the user would not want to give away in an specific transaction.
