Electronic Tags

- Nov 02, 2018 -

Electronic tags are also known as radio frequency tags, transponders, and data carriers; readers are also known as readouts, scanners, read heads, communicators, and readers (depending on whether the electronic tag can wirelessly overwrite data). The space (contactless) coupling of the RF signal is realized between the electronic tag and the reader through the coupling component; in the coupling channel, energy transfer and data exchange are realized according to the timing relationship.

Electronic tags are a tool to improve the efficiency and accuracy of recognition, and this technology will completely replace barcodes. RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes the target object and acquires relevant data through the radio frequency signal. The identification work can work in various harsh environments without manual intervention. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate. RFID tags are a groundbreaking technology: "First, you can identify a single, very specific object, rather than identifying a class of objects like a bar code. Second, it uses radio frequency, which can be read through external materials. Data is taken, and the barcode must rely on the laser to read the information. Third, multiple objects can be read at the same time, and the barcode can only be read one by one. In addition, the amount of information stored is also very large."
