YRP Ubiquitous Networking Laboratory led by Professor Ken Sakamura of the University of Tokyo unveiled the "UC-Watch," a radio frequency identification (RFID) reader embedded in a Wrist Watch.
The UC-Watch features a function to read data based on "ucode," an RFID code system that the Ubiquitous ID Center developed. Users can pick up objects that contain a RFID chip to read the info, which is then displayed on the 120 x 160pixel screen on the RFID wrist watch.
