What Is RFID? A Beginner’s Guide to Smart Tracking Technology

Radio Frequency Identification (RFID) is one of the most transformative technologies in the modern era of logistics, retail, healthcare, and supply chain management. As an automatic identification method, RFID utilizes radio waves to track and identify objects, animals, or people, offering greater efficiency, accuracy, and visibility across various industries. Understanding RFID Technology: The Basics RFID is a system composed of three core components: RFID tags, RFID readers, and a data processing system. This setup allows for wireless communication between objects without direct contact or line-of-sight requirements. RFID Tags These are small electronic devices that consist of a microchip and an antenna. RFID tags can be: Passive – No internal power source; powered by the RFID reader. Active – Contain a battery; used for longer-range applications. Semi-passive – Battery-assisted but only used to power the microchip, not the communication. RFID Readers RFID readers emit radio signals...
