What is RFID (Radio frequency identification)
Radio frequency identification (RFID) RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an animal , object or person. Function of RFID Every RFID system consists of three components: 1. scanning antenna 2. transceiver 3. transponder. RFID Reader.(Scanning antenna & transceiver) When the scanning antenna and transceiver are combined, they are referred to as an RFID reader or interrogator. There are two types of RFID readers - 1. fixed readers 2. mobile readers. The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. RFID Tag (Transponder) The transponder is in the RFID tag itself. The read range for RFID tags varies based on fo
