Radio Frequency Identification (RFID) technology is changing many industries by providing new solutions to old problems. RFID tags store and transmit data using radio waves and are crucial in retail, healthcare, and logistics. This article looks at how RFID tags are used in these industries through practical applications and real-world examples.

Types of RFID Tags
There are three main types of RFID tags, each suited for different applications:
1. Passive RFID Tags
Passive RFID tags are definitively powered by the electromagnetic energy transmitted from an RFID reader, thus eliminating the need for an internal power source. These tags are small, inexpensive, and have a long lifespan, making them ideal for inventory management and asset tracking.
2. Active RFID Tags
Active RFID tags have their power source, usually a battery, which allows them to transmit signals over longer distances. These tags are larger and more expensive but are useful for tracking high-value items or assets over large areas.
3. Semi-Passive RFID Tags
Semi-passive RFID tags, also known as battery-assisted passive (BAP) tags, have a small battery to power the microchip but rely on the reader to communicate. These tags are a hybrid between passive and active tags, offering a balance of range and cost.
