Rfid (radio frequency identification) is a wireless communication technology that can identify targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and the target. The rfid reader-writer communicates wirelessly with the rfid electronic tag through an antenna, and can read or write the tag identification code and memory data. Rfid reader can recognize moving objects, and can recognize multiple tags at a time. Commonly used rfid readers are divided into fixed rfid readers and handheld rfid readers.
The main function of rfid reader
1. Read the information stored in the rfid electronic tag;
2. Write information to RFID electronic tag;
3. Modify the information in the rfid electronic label.
Application scenarios of rfid reader
1. Production management
In production management, rfid reader can quickly check whether the types and quantities of goods in the box are consistent, and provide a basis for quality traceability.
2. Warehouse management
3. Store management
In the store management, the staff held the rfid reader to quickly check the displayed goods and inventory goods, and compared the system data to complete the replenishment. When receiving the goods, the clerk does not need to unpack the box. The rfid reader can be used to read the goods in the box in batches, which helps the clerk to check in time and effectively shorten the receipt time.
