RFID reader (short for Radio Frequency Identification), also known as "RFID reader", is radio frequency identification. It automatically identifies target objects and obtains relevant data through radio frequency identification signals without manual intervention. It can identify high-speed moving objects and simultaneously Identify multiple RFID tags and operate quickly and conveniently.
An RFID reader is a device that reads and writes RFID tag memory information. The RFID reader/writer communicates wirelessly with the RFID electronic tag through the antenna, and can read or write the tag identification code and memory data. At the same time, the reader/writer can also be connected to the computer network to complete data storage and management. A typical RFID reader contains an RFID radio frequency module (transmitter and receiver), a control unit and a reader antenna.
Functions and application advantages of RFID readers:
1.Provide energy to RFID tags
Usually tags are passive and require energy from an RFID reader to activate the tag in order to work properly.
2.Implement communication with RFID tags
The RFID reader/writer accesses the information data in the tag, including reading and writing data from the electronic tag.
3.Realize communication with computer
The RFID reader can achieve continuous communication with the computer through some interfaces, and provide data information to the computer for data exchange between the system terminal and the information management center, thereby solving the data management and information analysis needs of the entire system.
4.Achieve multiple electronic tag identification
The RFID reader can correctly identify multiple electronic tags within its working range, has anti-collision function, and can exchange data with multiple electronic tags.
5.Realize moving target recognition
RFID readers can not only identify stationary objects, but also moving objects.
6.RFID reader/writer has data recording function
Record the data information that needs to be recorded in real time to meet the needs of the information center for further data analysis.
