Six core functions of RF-ID readers
RFID reader, is a special device for reading and writing electronic tag information. It is the most important and complex component in the RFID system. Its operating mode is generally to actively ask the tag for information. The reader communicates with the RFID tag through the antenna. In this process, in addition to establishing communication, it is also necessary to complete the work of preventing collisions and identity verification.
In general, the main functions of RFID readers are:
1、Provide energy to RFID tags
Generally, the tag is passive and requires energy provided by the RFID reader to activate the tag in order to work normally.
2、Realize communication with RFID tags
The RFID reader accesses the information and data in the tag, including reading and writing the data of the electronic tag.
3、Realize communication with computer
The RFID handheld reader can realize the connection and 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, so as to solve the data management and information analysis needs of the entire system.
4、Realize multiple electronic tag identification
The reader can correctly identify multiple electronic tags within its working range, has an anti-collision function, and can exchange data with multiple electronic tags.
5、Realize moving target recognition
The reader can recognize not only stationary objects, but also moving objects.
6、Reader with data recording function
Real-time recording of the data information that needs to be recorded to meet the needs of the information center for further data analysis.
With the continuous popularization of RFID technology applications, the application demand for RFID readers is increasing, and the types of products are becoming more and more abundant. In general, in the future, readers will continue to develop in the direction of intelligence, miniaturization and integration.
