the world at your fingers

the history of money goes something like this: first there was the flintstones, where we exchanged rocks for commodities. then we moved up to simply trading goods for goods. then, of course, gold coins. from gold coins we moved on to paper money, and finally up to credit cards. now, none of that is needed anymore. because we live in the future, we can pay in fingerprints.

just stick your finger on the cute blue gel-pad of this german supermarket, it will recognize your individuality through the magic of computers, and you can pay for your food through your saved debit account in their systems.
