RFID is a non-contact identification technology from a professional point of view, which is divided into two types: active and passive. Working principle: The RFID reader emits radio frequency, passes through the coil of the electronic tag, generates a signal, and the reader reads and decodes the information to complete the entire identification process.
The industrial portable tablet uses radio frequency identification technology (RFID), GPS, camera, controller and other methods of cognition, capture, and accurate measurement to collect materials at any time, continuously and automatically store, display information/opinion feedback in real time, and fully automatic transmission.
