Actually, over the last ten decade, France developed, tested, implemented and is now discarding the entire idea of credstick, except that it was a card (either embedded on bank card or a separate, anonymous, card): Moneo. Germany has a similar tech called "Geldkarte" but I don't know if it had been more successful.

It's implemented in as good as every bank card.
Using it is up to you, you can reload it at ATM's.

Plastic "Paper" Money is going to be here for a long time, methinks.

My question is: does it actually taste like mint, or are they lying to us?
