<h2>What Are RFID Tags?</h2>

RFID tags are compact devices consisting of a microchip and an antenna. The microchip stores unique identification data, while the antenna facilitates communication with RFID readers via radio frequency signals. Unlike barcodes, which require visual scanning, RFID tags can be read from a distance and through obstacles, making them highly versatile. They operate in different frequency ranges, including low frequency (LF), high frequency (HF), and ultra-high frequency (UHF), each suited for specific use cases based on read range and environmental factors.


<h2>Types of RFID Tags</h2>

RFID tags are categorized based on their power source and functionality:
- <h3>Passive RFID Tags:</h3> These do not have an internal power source. Instead, they draw energy from the reader's radio waves to transmit data. They are cost-effective, durable, and ideal for short-range applications like inventory management and access control.
- <h3>Active RFID Tags:</h3> Equipped with a battery, active tags can transmit signals over longer distances (up to 100 meters). They are used in real-time tracking, such as in logistics and large-scale asset monitoring.
- <h3>Semi-Passive RFID Tags:</h3> These combine features of both passive and active tags, using a battery for enhanced functionality (e.g., sensors) but relying on the reader for communication. They are common in environmental monitoring, such as tracking temperature-sensitive goods.

<h2>Key Applications of RFID Tags</h2>

RFID technology has permeated numerous industries due to its efficiency and scalability:
- <h3>Retail and Supply Chain:</h3> RFID tags streamline inventory management, reduce theft, and enable automated checkout systems. For instance, retailers use UHF RFID to track products from warehouse to point-of-sale, improving accuracy and reducing labor costs.
- <h3>Healthcare:</h3> Hospitals employ RFID tags to monitor medical equipment, manag The Use of RFID for Human Identity Verification
