  • Features Of Uhf Rfid

    UHF RFID technology is currently one of the most active technical fields of radio frequency identification technology. Compared with low-frequency and high-frequency RFID, UHF RFID has the following characteristics: Working distance Compared with low-frequency and high-frequency transponders, UHF RFID transponders working in the UHF band should have a longer read-write distance, usually greater than 1m. With the wide application of active transponders, the reading and writing distance has further expanded. Due to the long read and write distance, RFID technology has been widely used in logistics, supply chain management, access control and other fields. 2. Antenna In the ultra-high frequency band, the size of the antenna of the transponder is small, and the miniaturization and miniaturization of the antenna have…

  • Application Fields Of Rfid Technology And System

    For UHF passive RFID tags, each tag has its own unique number. The most common use is to replace ordinary bar codes and affix them to various items in order to identify the items. Generally used with UHF reader. RFID tags can wirelessly transmit information to UHF readers within a range of 10 meters, enabling warehouses, workshops, supermarkets, and other occasions. Group scanning can be performed on items, eliminating the need to use a laser barcode reader to scan the items one by one. The application fields of RFID technology and system are very broad, involving all aspects of industry, commerce, transportation, warehousing, logistics and military. For example, the world ’s largest goods seller, Wal-Mart, requires its top 100 suppliers…

  • Uhf Reid Readers Want To Accept Anti-collision Technology

    In the UHF passive radio frequency identification system, when the tag communicates with the reader, the reader needs to send the carrier directly to provide power for the tag, and the tag sends information to the reader by modulating backscatter. The reader receives the tag signal and demodulates it into two IQ baseband signals through a quadrature demodulator. The two signals have a phase difference of 900. The baseband signal is processed by differential amplification and filtering, and then passed through the ADC analog-to-digital converter to complete the baseband analog signal Conversion to baseband digital signal, the converted digital baseband signal is sent to the programmable logic device or central processing unit, and the programmable logic device or central processing…

  • Rfid Reader Function

    The reason why the RFID reader is very important is determined by its function. Its main functions are as follows: ① Communication with electronic tags: The most common is to read the tags. This function requires a reliable software algorithm to ensure safety and reliability. In addition to reading, sometimes it is necessary to write to the label, so that the label can be produced in batches, and the user can write to the label according to his own needs; ②Enable tags: In the case of passive or semi-passive tags, readers need to provide energy to activate electronic tags around the RF field; the range that readers can reach in the RF field is mainly determined by the size of…

  • Desktop Reader Use And Main Functions

    1.Desktop Reader Use Can be used for item identification and data collection, read and write electronic tags. 2. Main functions of desktop reader 1) Wake-up tags: Only the wake-up tags can communicate with the reader to prevent interference from other tags outside the system and ensure the reliability and accuracy of the tag information exchange between the reader and the system. 2) Reading tag data: Not only the ID number of the tag, but also the data in the designated tag storage area: Not only the data of a single tag, but also the number of tags in the antenna wave range can be read at the same time. data. 3) Write tag data: You can write data to the…
