RFIDmerkistä

RFIDmerkistä refers to an RFID tag, a small electronic device that uses radio waves to transmit information. These tags typically consist of a microchip and an antenna. The microchip stores data, while the antenna transmits and receives radio signals. RFID tags are passive, meaning they do not have their own power source and are activated by the radio waves emitted by an RFID reader.

There are several types of RFID tags, including low frequency, high frequency, and ultra-high frequency. Each type operates at different radio frequencies and has varying read ranges and data transfer speeds. The choice of RFID tag depends on the specific application requirements, such as the distance at which the tag needs to be read and the amount of data to be stored.

RFID tags are widely used in various industries for inventory management, asset tracking, access control, and supply chain management. For example, retailers use RFID tags to track inventory in real-time, reducing stockouts and improving efficiency. In logistics, they help monitor the movement of goods throughout the supply chain. Access control systems utilize RFID tags for secure entry to buildings or restricted areas. The technology offers a contactless and automated way to identify and track objects, providing significant advantages over traditional methods.
