RFID Tag
An RFID tag is a small electronic device that contains an RFID chip and an antenna, used for identification and tracking purposes. RFID tags are commonly used in applications such as inventory management, access control, asset tracking, and contactless payment systems. The RFID chip stores electronically encoded information, which can be wirelessly read and transmitted to an RFID reader or scanner when activated by radio waves. RFID tags come in various forms and configurations, including passive, active, and battery-assisted passive (BAP) tags. Passive RFID tags do not have an internal power source and rely on energy harvested from the RFID reader's radio waves for operation, while active and BAP tags have internal power sources such as batteries. RFID tags can be attached to objects, animals, or people, enabling them to be identified and tracked remotely. They play a crucial role in enabling the functionality of RFID technology across a wide range of industries and applications.
