Here in Denmark we are in the process of "upgrading" the way we pay for public transport. The RFID based payment card, similar to the Oyster card used in London, is an upgrade insofar that it makes payment slightly more convenient, but in terms of technology it aims to add yet another device to our bulging pockets. Considering that Japan has already been using mobile phones for micro payments for years this seems like an expensive, slow and ultimately pointless alternative.
