Radio tags, also known as radio frequency identification (RFID) tags, are small electronic devices that consist of a chip and an antenna. They are used for identification and tracking purposes in various applications. The chip stores data, which can be read and transmitted wirelessly via radio waves by an RFID reader.
There are two main types of RFID tags: active and passive. Active tags have their own power source (such as a battery) and can transmit data over longer distances, while passive tags rely on the electromagnetic energy emitted by the RFID reader to power the chip and transmit data over shorter distances.
RFID tags have a wide range of applications, including inventory management, access control, asset tracking, supply chain management, livestock tracking, and electronic toll collection. They offer advantages such as automation, accuracy, and efficiency in data collection and tracking processes.
The technology has been widely adopted across different industries due to its ability to automate processes, improve efficiency, and provide real-time visibility into assets and inventory. However, concerns about privacy and security have also been raised regarding the potential for unauthorized tracking and data interception.
