## Introduction to RFID Technology


Radio-Frequency Identification (RFID) tags have transformed how businesses and organizations track, identify, and manage assets across numerous industries. These small electronic devices consist of a microchip attached to an antenna that enables wireless communication with RFID readers through radio waves. Unlike traditional barcodes that require line-of-sight scanning, **RFID tags** can be read from a distance and through various materials, making them incredibly versatile for countless applications. The technology has evolved significantly since its initial development during World War II for aircraft identification, becoming more sophisticated, affordable, and widely adopted in recent decades.


The fundamental working principle of **RFID tags** involves three main components: the tag itself (transponder), the reader (interrogator), and the backend database system. When an RFID reader emits radio waves, the tag's antenna captures the energy and activates the microchip, which then transmits its stored data back to the reader. This seamless communication happens in milliseconds, allowing for rapid identification and data collection without physical contact. The efficiency of this process has made RFID technology indispensable in supply chain management, retail, healthcare, and many other sectors where accurate, real-time tracking is crucial.

## Types of RFID Tags and Their Characteristics



### Passive RFID Tags
Passive **RFID tags** represent the most common and cost-effective variant in the market. These tags contain no internal power source and instead rely entirely on the electromagnetic energy transmitted by the RFID reader to power up and respond. The absence of a battery makes passive tags smaller, lighter, and more durable with virtually unlimited operational life. They're typically less expensive to manufacture, ranging from just a few cents to a couple of dollars per tag depending on features and volume. However, passive tags have shorter read ranges—usually from a few centimeters to several meters—making The Use of RFID for Human Identity Verification
