Types of RFID Tags and UHF RFID Tags

RFID tags, or Radio Frequency Identification tags, are small electronic devices that use radio waves to transmit data. Each tag contains a microchip and an antenna, allowing it to send information to an RFID reader. This technology enables automatic identification and tracking of objects, making it invaluable for various applications.

Types of RFID Tags

RFID tags can be classified into three main categories:

1. Passive RFID Tags: These tags do not have a power source. They are activated by the electromagnetic field produced by an RFID reader. Passive tags are cost-effective and commonly used for inventory management.

2. Active RFID Tags: These tags come with a built-in power source, allowing them to transmit signals over longer distances. Active RFID tags are often used for tracking high-value assets or in environments where real-time data is crucial.

3. Semi-Passive RFID Tags: These tags have a battery that powers the chip but rely on the RFID reader’s signal to communicate. They offer a middle ground in terms of cost and performance.
