Automatic recognition of long-distance readers and writers is an important method and means for automatic reading and input of information data. It is a comprehensive science and technology based on the development of computer technology and communication technology. In recent decades, the technology of automatic identification has made great progress. It has initially formed a high-tech technology including bar code technology, magnetic stripe (card) technology, radio frequency technology, optical character recognition technology, biometric technology, long-distance reader and writer, which integrates computer, light, machine, electricity, communication and other technologies.
Generally, the energy required in the tag of the remote reader is much smaller than that of the reader, which requires the reader to have a high receiving sensitivity. In some systems, the receiving and transmitting of the long-distance reader are independent of each other, especially when the frequencies of the uplink and downlink signals are different.
Technically speaking, it is possible to choose all appropriate power values for different applications, but sometimes some artificial restrictions must be obeyed. Generally, the transmission power of 100MW ~ 500MW is suitable for various RFID remote reader systems. Remote readers and writers in different areas and fields must comply with the regulations of the radio wave management committee.
Dw04 long-distance reader has many advantages, such as multi protocol compatibility, fast reading rate, multi label reading, linear polarization antenna, waterproof appearance design, etc. it can be widely used in various RFID systems
The typical applications of the remote reader are as follows:
1) Logistics and storage management: the flow and storage management of goods and the flow management of mail, parcels, transportation baggage, etc;
2) Intelligent parking lot management: parking lot management and charge automation;
3) Production line management: identification of fixed point of production process;
4) Product anti-counterfeiting detection: use the label memory write protection function to identify the authenticity of the product;
5) Other fields: club management, library, student status, consumption management, attendance management, dining management, pool management and other systems are widely used
