Abstract
Description
Technical Field

[0002] RFID generally refers to radio frequency identification technology, also known as wireless radio frequency identification, which is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and the specific target. The basic working principle of RFID technology is not complicated: after the electronic tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (passive tag or passive tag), or the tag actively sends a signal of a certain frequency (active tag or active tag), and the reader reads and decodes the information and sends it to the central information system for relevant data processing.
[0003] When a large number of RFID tags need to be scanned, registered or proofread, existing scanning equipment often simply sets a fixed block to scan in position. This is convenient when the RFID position of a single type of product is uniformly fixed, but when faced with a large number of different specifications and multiple RFID positions of products, the fixed block and scanning head are not soul-enough and reduce work efficiency.
