This fall, KDDI may release RFID reader attachment for cell phones

If you remember, KDDI was testing RFID readers for mobile phones – it was more than a year ago. Recently, the company demoed RFID reader attachment for mobile phones at Wireless Japan 2006. It can be attached on the back of a mobile phone (the size: 106 x 50 x 16mm) and reads Hitachi’s mu-Chip tags. The attachment communicates with a mobile phone via Bluetooth — information captured from RFID tags is sent to the phone via Serial Port Profile. The reader can be controlled by using a BREW application that runs on a mobile phone. Anyway, what sounds exciting is that the company may release this RFID reader attachment soon, probably this fall.
