RFID System for Medical Charts Management and Its Enhancement of Recognition Property

Many hospitals adopt hand-in-out system for patient management and patient¿s disease history report. It causes medical report sheets in-out to complicate in a hospital¿s related department and it is a heavy burden to worker. Sometimes, it can give rise to exchange medical report sheets between their patients by mistakes. That can result in a serious medical accident, especially for complete cure or emergency cure. Therefore, we propose to use RFID system for medical chart management. RFID system can recognize a lot of tags during short time simultaneously. It has a wide range for possible frequencies and it is strong material about security. Because of this reason, lots of business systems adopt RFID. There are two issues which should be considered when adopting RFID medical chart management system. First one is how to identify more tags simultaneously and correctly. For this we will propose optimized reader allocation methods. Second one is to reduce read time. For this we suggest new double tag elimination method.
