Fujitsu develops compact RFID for wearables

Fujitsu Laboratories has developed a compact RFID tag that works on surfaces such as metal, which can otherwise impede radio waves. The tag, 30mm long, 25mm wide and 0.5mm thick, can be attached to any material, including plastic cards, wearables and metal objects. Despite its small size, it has a communication range of about 2 meters.
