RFID (Radio Frequency Identification) is a wireless form of automated identification technology. RFID is sometimes called Dedicated Short Range Communication (DSRC) .RFID system is used for identification of patient information in hospitals. It is applied in many fields. This technology has the following advantages: if an object has a Tag, Reader can recognize the ID of an object without contact. Here we are using EM-18 Reader Module that can read 100 to 300 tags per second. In this paper we proposed the system which displays the information of patient disease, ward number on the LCD screen when it scans the RFID Tags. RFID provides long term benefits to patients, in process of traceability and security of patient information system.
