RFID electronic label introduction!UHF Sticker factory

RFID electronic tag is also called radio frequency tag, it is composed of three parts: tag, reader and data transmission and processing system. The tag is also called an electronic tag or a smart tag. It is a chip with an antenna in the memory, and the chip stores information that can identify the target. RFID tags have the characteristics of durability, strong penetration of information reception and transmission, large storage capacity and variety of information. Some RFID tags support reading and writing functions, and the information of the target object can be updated at any time. Readers are divided into two types: handheld and fixed, which consist of transmitter, receiver, control module and transceiver. The transceiver is connected to the control computer or programmable logic controller (PLC) to realize its communication function. The reader also has an antenna to receive and transmit information. Readers are also called reading devices, scanners, reading heads, communicators, readers (depending on whether the electronic tags can rewrite data wirelessly). The electronic tag and the reader realize the spatial (non-contact) coupling of the radio frequency signal through the coupling element; in the coupling channel, according to the timing relationship, the energy transfer and data exchange are realized.

　 Tag: It is composed of coupling components and chips. Each tag has a unique electronic code. The high-capacity electronic tag has a user-writeable storage space and is attached to an object to identify the target object.

　　 Reader: A device that reads (and sometimes writes) tag information, which can be designed as a handheld or fixed type;

　　 Antenna: Transmit radio frequency signals between the tag and the reader.

　　 characteristics

　　Data storage: Compared with traditional forms 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 bar codes, there is no need to align and scan in a straight line, and the reading and writing speed is faster, multi-target recognition and motion recognition are possible.

　　Easy to use: small size, easy to package, can be embedded in the product.

　　Security: dedicated chip, unique serial number, difficult to copy.

　　 Durable: no mechanical failure, long life, and resistance to harsh environments.
