Sorry, we don’t have a picture, but during this year’s Embedded Systems Expo and Conference held at Tokyo Big Sight, Professor Ken Sakamura of the University of Tokyo unveiled the “UC-Watch,” a radio frequency identification (RFID) reader developed by the YRP Ubiquitous Networking Laboratory that Sakamura directs.
The UC-Watch features a function to read data based on “ucode,” an RFID numbering system that the Ubiquitous ID Center standardized. Scanned data is transmitted through weak radio waves.
The watch has a screen of 120 x 160 dots. The time and date each are displayed as a clock function, and background images and menus can be changed. It weighs around 100g without batteries. The company is working on reducing the weight.
