RFID SYSTEM
Radio Frequency Identification System is a technology based identification system which helps identifying objects just through the tags attached to them, without requiring any light of sight between the tags and the tag reader. All that is needed is radio communication between the tag and the reader Main Components of a RFID System A RFID tag: It consists of a silicon microchip attached to a small antenna and mounted on a substrate and encapsulated in different materials like plastic or glass veil and with an adhesive on the back side to be attached to objects. A reader: It consists of a scanner with antennas to transmit and receive signals and is responsible for communication with the tag and receives the information from the tag. A Processor or a Controller : It can be a host computer with a Microprocessor or a microcontroller which receives the reader input and process the data. Types of RFID Systems: Active RFID system: These are ...
