an “official” third party product. LEGO has announced yesterday an
official partnership with Codatex producing the NXT RFID Sensor seen below. The package contains a sensor and two tags, with holes matching Technic pegs.

Reading distance up to 3 cm depending on transponder size and orientation
Transparent front cap with LED signal at detection of a transponder
Auto power off for saving battery power
Firmware upgrade feature for future enhancements (saving hardware cost)
