Thats a sweet idea, i would really like to have something like coin.

The problem is that in Finland there is very few places that uses the "swipe" your card and sign method anymore. Back some 2-3 years ago it was a custom, but for security reasons (anyone can swipe a stolen card and sign it, the law does not require an ID unless the amount being paid is over 100 euros) it was abandoned and now you simply enter your PIN and that that.

Im not sure about other countries, but atm this is the norm in Finland.
