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.

The introduction of radio frequency identification (RFID) technology into cold chain system will be essentials for the better quality preservation of chilled products in the near future. The object of this study is to analyze the trends of international standardization activity for cold chain system and RFID packaging. The standardization of RFID technology is related to SC31 of ISO/IEC JTC1. The established standard from EPCglobal includes the air interface of UHF substitute actors, the control of EPC tag data and the event collected from RFID readers, the directory services and information storage of ONS and EPCIS, and securities. Also, EPC standards include the sensor functions of the cold chain. In Korea, the RFID packaging related techniques and their engineering standard are less studied as compared with Europe or North America. For effective application of RFID in the cold chain and packaging, scientific and systematic researches on RFID, including technical standards for domestic RFID frequency, will be key elements for preoccupation of these application techniques.
