The ECB are looking into RFID, I think it should have been in place by now.

However, given the growth in credit and debit card transactions, which have
overtaken cash payments in the UK, is there much point? Banks dislike cash,
there are security risks, reserve issues and the FRB system leaves them
exposed to theoretical runs and credit crunches. The banks love the ability
to generate liquidity for credit card transactions and all the associated
merchant fees.

Does paper money have much of a future? Enplanting notes with RFID chips is
an obvious bridge technology, government would certainly like to track all
possible transactions.
