## Introduction to RFID Technology



Radio-Frequency Identification (RFID) technology has transformed how businesses and organizations manage assets, track inventory, and secure access. Unlike traditional barcodes, RFID tags do not require line-of-sight scanning and can store significantly more data. These small electronic devices consist of a microchip attached to an antenna, enabling them to transmit information to an RFID reader via radio waves. The versatility of RFID tags has led to their adoption across various industries, from retail and healthcare to logistics and security.




The fundamental principle behind RFID technology is simple yet powerful. When an RFID tag comes within range of a reader, the reader's radio waves power the tag's chip, which then sends back stored data. This process allows for rapid, automated identification and data collection. There are three main types of RFID tags: passive, active, and semi-passive. Passive tags rely entirely on the reader for power and are commonly used for short-range applications. Active tags have their own power source, enabling them to transmit signals over longer distances. Semi-passive tags use a battery to power the chip but rely on the reader for communication.

The evolution of RFID technology has been driven by advancements in microelectronics and wireless communication. Early RFID systems were bulky and expensive, limiting their use to high-value applications. However, miniaturization and cost reduction have made RFID tags affordable and practical for everyday use. Today, RFID tags are embedded in products, animals, and even humans, providing a seamless way to collect and manage information.

## How RFID Tags Work

Understanding the mechanics of RFID tags is essential to appreciating their capabilities. At its core, an RFID system comprises three components: the tag, the reader, and the backend system. The tag, which contains a unique identifier and possibly additional data, is attached to an object. The reader emits radio waves that activate the tag and receive its transmitted data. The backend system, often a database or software application, processes and stores this information for further use.
