identify and track tags attached to objects These tags contain a microchip that stores unique identification data which can be accessed by a reader device without physical contact How RFID Works 1 Reader The reader device transmits radio waves to the RFID tag 2 Tag The tag receives the radio waves and uses the energy to power its internal chip 3 Data Transmission The tags microchip transmits its unique identifier to the reader 2 4 Reader Processing The reader receives the data and processes it according to its specific application Types of RFID Tags Passive Tags Rely entirely on the readers radio waves for power and data transmission Active Tags Have their own internal battery enabling them to transmit data at greater distances and frequencies SemiPassive Tags Combine features of both passive and active tags using the readers signal for data transmission but relying on an internal battery for power Applications of RFID Technology Access Control Building access security systems time and attendance tracking Inventory Management Tracking inventory levels supply chain management Asset Tracking Locating and monitoring equipment vehicles and other assets Payment Systems
