Problems solved by technology

However, if the radio frequency identification reader transmits the digital signal generated by it in a wired manner, it needs to set up physical lines to connect the radio frequency identification reader and the back-end system, so its construction cost is relatively high, and the back-end system The wiring is more complicated
Especially for gate-type RFID readers and fixed-type RFID readers, because they need to be installed in specific locations, the erection of physical lines is extremely inconvenient
If the RFID reader transmits the digital signal it generates wirelessly, the wireless signal will interfere with other devices, and its cost is relatively high, so it limits the application of the RFID reader

Abstract

The invention provides an RFID reader which comprises an antenna, an RFID reading unit, an encoder and a display screen, wherein, the antenna receives an RF signal sent by an RFID tag; the RFID reading unit is connected with the antenna for processing the RF signal and generating a corresponding digital signal; the encoder is connected with the RFID reading unit for encoding the digital signal to generate a two-dimensional code signal; and the display screen is connected with encoder for displaying the two-dimensional code signal so that the RFID reader can output the two-dimensional code signal.

Description

technical field [0001] The present invention relates to a radio frequency identification (Radio Frequency Identification, RFID) reader, and in particular to a radio frequency identification reader with a two-dimensional code display function, a reading method and a corresponding radio frequency identification reading system. Background technique [0002] Existing RFID readers are generally divided into gate RFID readers, fixed RFID readers, integrated RFID readers, handheld RFID readers and embedded RFID readers These five categories use the antenna to read the radio frequency signal sent by the radio frequency identification tag (RFID Tag), and process the received radio frequency signal to generate a corresponding digital signal, and then output the generated digital signal to the rear end system for subsequent processing. However, the existing RFID readers generally output the digital signal generated by the RFID reader to the back-end system in a wired or wireless manne...
