Method for improving radio frequency identification (RFID) tag reading success rate

Abstract

The invention relates to a method for improving RFID tag reading success rate, used for quickly reading and writing a large quantity of tags in the internet of things and belonging to the technical field of radio frequency identification (RFID) tag reading and writing. The method is mainly used for solving the problem of low tag reading success rate and low reading efficiency under the influence of noise interference and signal distortion when the RFID tags are quickly read in the application of the internet of things. According to the method, tag data read from the tags are corrected by encoding and coding error correcting codes, so that the tag reading efficiency and the system stability of the internet of things are improved, and the coverage area of a reader is improved. In addition, the invention provides two different implementation ways, one is to integrate an electronic error correction coding module in a tag, and the other one is to apply the electronic error correction coding module to the existing tag directly, and write electronic error correction codes into a tag storage area together with tag data by a reader-writer or a terminal system when tag data is written in.
