Using active tag like ZigBee is an innovative application of this technology, however, it is still required to charge the battery after certain period. Is it possible to adopt RFID technology for longer distance? After further development of Sengital (SenMedia) R&D team, the solution came out. Using RFID passive tag with longer range antenna for both RFID tag and RFID receiver with higher transmission power, the RFID tags were able to be detected when it was dropped very fast to pass through the receiver.
