The reader module is the control center and intelligent unit of the entire reader, and it is the "brain" of the reader. The logic control module issues instructions when the reader is working, and the interface module performs different operations according to different instructions.

The microcontroller can complete signal encoding and decoding, data encryption and decryption, and execution of anti-collision algorithms; the storage unit is responsible for storing some programs and data; the application interface is responsible for communication with input or output.

The reason why the RFID reader is very important is determined by its function. Its main functions are as follows:

(1) The most common is to read tags. This function requires a reliable software algorithm to ensure safety and reliability. In addition to reading, it is sometimes necessary to write to the label, so that the label can be mass-produced, and the user can write to the label according to his needs.

(2) When the tag is passive or semi-passive, the reader is required to provide energy to activate the electronic tags around the field; the range that the reader can reach in the radiofrequency field is mainly determined by the size and the reader. The size of the antenna is mainly considered according to the application requirements, and the output power has different regulations in different countries and regions.

(3) Realize the communication with the computer network: this function is also very important, the reader can use some interfaces to realize the communication with the upper computer, and can provide some necessary information to the upper computer.

(4) The reader can correctly identify multiple tags within its working range.

(5) The reader can recognize not only stationary objects but also moving objects.

(6) For some errors in the recognition process, the reader can send out some prompts.

(7) For the tag, the reader can read the battery information of the active tag: such as the total battery power and remaining power of the battery.

    Why do foreign cyclists start wearing shoes with NFC labelsNov 27,2023
    Technical expert Simonelli suffered a serious accident during a motorcycle race more than a decade ago. At that time, he was taken to the nearest hospital and no one knew him, resulting in him being unconscious for two days without anyone being able to contact his family because he did not carry his identity information with him. Leveraging his knowledge in NFC technology, he decided to develop a solution based on this technology.

    The characteristics and application advantages of RFID ear tags in different frequency bandsNov 10,2023
    Comparative analysis of the characteristics and application advantages of RFID ear tags in different frequency bands Most RFID tags used in animal husbandry and breeding use ear tags. Currently, ear tags in the low-frequency and ultra-high frequency bands used in China are more common, while high-frequency tags are less commonly used. What are the characteristics of ear tags in different frequency bands?
