The Codatex RFID Sensor works with 125 kHz transponders and can read five-byte transponder numbers into the NXT Intelligent Brick. The RFID Sensor has three different reading modes: single read, continuous read, and stop. The maximum reading distance depends on the transponder size; for example, the keyfob will read up to a maximum distance of 30 mm. One RFID Sensor, five keyfob transponders, five clear disc transponders, and two card transponders are included in this set. Requires NXT firmware 1.05 or later.
