Study of Reading Rate & Small UHF RFID Tags in The Key Management System in a Metallic Cabinet
You-Chung Chung · 2010
This paper shows the key management system in a small metallic cabinet using a small UHF RFID tags. Each key chain with a key has a custom-designed small RFID tag antenna. There are 6 metallic racks in the small cabinet, and each rack can hold 60 key chains. Therefore, the small cabinet can hold 360 key chains with tags. The 360 key chains with RFID tags in a cabinet are recognized by RFID key chain management system. Even though it is hard to recognize 360 tags in the a cabinet, this RFID key management system with small custom designed RFID tags can recognize all the tags in the small cabinet. To read the all the tags, the locations of antennas and tag shapes are optimized. The reading rates based on the bios-version of the reader and the locations of the reader antennas are compared.
