A reader that uses ultra-high frequency between the range of 840 MHz and 960 MHz is known as a UHF RFID reader. An RFID reader identifies the tags that are affixed to objects. It emits radio waves through the antenna used inside an RFID tag. The radio waves then activate the tag, and the tag generates a unique identification number. Afterwards, the reader collects the data from the tag and transmits the data into the system to get meaningful information about the object. This whole process works on the principle of Automatic Identification and Data Capture (AIDC). A UHF RFID reader is one of the types of RFID reader. Ultra-high frequency is supported by ISO/IEC 18000-6:2010 that provides the air interface for the frequency.
In other words, the size of radio waves in the reader is large, and these can communicate with its components rapidly. The UHF RFID reader empowers to read multiple tags at once and also with a very high speed. It is because of the fast data transfer process of the UHF RFID reader. The reading range of this type of reader is more in comparison to readers with low frequencies. There is a high range of variety available for UHF RFID readers. The readers may be fixed or portable based on need. These are also available on the basis of range, i.e., short, medium, and long-range. The UHF readers are very beneficial in vehicle management and parking management.
