Generally, an RFID system consists of tags, readers, communication links and back-end systems.
The radio frequency identification (RFID) system is composed of RFID tags, readers, back-end systems, air interface communication links between tags and readers, and network transmission communication links between readers and back-end systems. Automatic identification system. Usually, the reader emits electromagnetic field energy in an area. When the RFID tag passes through this area, it senses the signal of the reader and then performs corresponding feedback. The reader accepts the signal sent by the RFID tag, decodes and verifies the integrity of the data. After waiting for multiple interaction processes, the information is sent to the back-end system to complete the corresponding processing work.
RFID tags contain chips and antennas. RFID tags are attached to any object. The main task of the RFID tag antenna is to collect energy and transmit the unique tag ID. The tag chip can contain data related to any product, such as the manufacturer's name, model number, etc., and can store more information than barcodes.
The RFID reader can read and write RFID tags, and has the functions of tag inventory, rewriting and locking the data in the tag chip.
A communication link is a physical channel between two nodes in an RFID system. Including the air interface communication link between the reader and the tag and the network transmission communication link between the reader and the back-end system.
The back-end system is a system composed of software and hardware such as middleware, computer terminals, databases, and servers.
