RFID in Japan

Nanaco is yet another RFID emoney system (like Suica and Edy) introduced by Seven Eleven Japan about a month ago. There are already over 1 million Nanaco users. It had been available only in big cities until recently, but, since May 28, all Seven Eleven stores in Japan accept Nanaco payment.

Speaking of cutsiness of digital money, I give Nanaco two thumbs up.
