Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called reading devices, scanners, read heads, communicators, and readers (depending on whether the electronic tag can rewrite data wirelessly). The space (contactless) coupling of the radio frequency signal is realized between the electronic tag and the reader through the coupling element; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship.
RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and identify multiple tags at the same time, which is fast and convenient to operate.
RFID electronic tags are a breakthrough technology: "First, it can identify a single very specific object, instead of only identifying one type of object like a barcode; second, it uses radio frequency and can be read through external materials. To get data, barcodes must be read by lasers; third, multiple objects can be read at the same time, while barcodes can only be read one by one. In addition, the amount of information stored is also very large.”
Data storage: Compared with the traditional form of tags, the capacity is larger (1bit-1024bit), and the data can be updated at any time and can be read and written.
Reading and writing speed: Compared with barcodes, it does not need to scan in a straight line, and the reading and writing speed is faster, and it can recognize multiple targets and motion.
Easy to use: small size, easy to package, can be embedded in the product.
Safety: special chip, unique serial number, difficult to copy.
Durable: No mechanical failure, long life, resistant to harsh environments.
Induction effect: much better than normal
