RFID reader, that is, radio frequency identification, automatically identifies the target object and obtains relevant data through the radio frequency identification signal. It can identify high-speed moving objects and identify multiple RFID tags at the same time, and the operation is fast and convenient. The UHF reader is a radio frequency identification device that works in the UHF frequency band, generally an RFID reader that works in the frequency band of 840-960MHz (there are different standards in different regions of the world).

The UHF reader uses electromagnetic wave reflection coupling to read the stored information in the UHF RFID tag. It has the advantages of long-distance reading and group reading. The RFID electronic tags used in passive UHF RFID do not need The use of batteries is low cost and can greatly reduce project costs.

超高频射频识别阅读器分为射频频率:再保险ader, high frequency reader, low frequency reader dual frequency reader, 2.4G microwave band RFID card reader, 5.8G microwave band RFID card reader, etc. Relatively common applications are mainly UHF readers.

In recent years, UHF reader products have been widely used in warehousing and logistics management, asset management, personnel management, clothing management, library management, intelligent transportation, production line automation, retail industry and other fields.

Now let's learn more about UHF readers! At present, the more common UHF readers on the market mainly include: split fixed reader, integrated fixed reader, desktop card issuer, portable Handheld reader, AGV car reader, industrial embedded reader, etc.

1. Split type fixed reader

Its main feature is that the RFID read-write module and the read-write antenna are separated, and different reader modules and antennas can be configured according to the requirements of different application scenarios. Readers are divided into single-channel, dual-channel, four-channel and eight-channel, the most of which is Jietong’s 32-channel antenna interface, which can be widely used in asset management, book management, clothing management, bank seal management and other fields.

2. Integrated fixed reader

The biggest feature of the integrated type is that the RFID read-write module and the antenna are assembled into an integrated machine, which has the characteristics of strong anti-interference ability, excellent protection performance, convenient installation and use, and high cost performance. It can be mainly used in parking lot management, warehouse material entry and exit supervision and identification management, airport luggage package identification management, intelligent manufacturing, construction site personnel entry and exit and other fields.

3. Desktop card issuer

The main function of the desktop card issuer is to issue cards and initialize RFID tag data. It can read, write, authorize, and format tags. It is suitable for RFID card issuance in various fields such as warehousing, logistics, clothing, and production line management. . It is characterized by small size, beautiful appearance, and convenient placement on the desktop, also known as desktop reader.

4. Portable handheld reader

The biggest feature of the portable handheld reader is its mobility and portability. The operating system is mainly Android, which is divided into two types: with handle and without handle. The reading distance is within 0-8 meters, and barcode, fingerprint, and ID card recognition can be expanded and other functions. Adapt to mobile data collection in harsh indoor and outdoor environments, mainly used in material inventory, asset management, library management, information entry, etc.

5. AGV car reader

AGV is the English abbreviation of unmanned guided vehicle, which refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, which can drive along the prescribed guidance route, and does not require a driver in industrial applications.

The AGV trolley reader is characterized by its compact appearance, easy installation, IP65 protection level, and adaptability to harsh working environments. The response speed is fast, and the command data can still be read reliably when the AGV runs at a speed of 2m/s.

6. Industrial embedded reader

The characteristic of the industrial embedded reader is that it uses an embedded UHF read-write module in different working equipment as an I/O module for data acquisition, and is connected with the industrial control host to realize different functional applications of the equipment. Now more and more industrial Internet of Things, intelligent manufacturing, and automation equipment adopt this model, the most common one is RFID printers.
