Problems solved by technology

[0004] However, it has been found in practice that after the above-mentioned anti-collision algorithm is optimized to a certain extent, no matter how optimized it is, some tags cannot be activated and / or recognized, resulting in a decrease in the reader's card reading recognition rate.

Abstract

The invention relates to the field of radio frequency identification, and provides a card reading method, device and computer-readable storage medium of a radio frequency identification reader, so as to improve the card reading recognition rate of the reader. The method includes: by dividing the effective card reading area of ​​the reader and adjusting the antenna of the reader, judging whether the label read in the area indicated by the antenna is an effective label; if the label read in the area indicated by the antenna is an effective label, The valid tags are saved and processed later; if the tags read in the area pointed to by the antenna are invalid tags, the invalid tags are filtered. On the one hand, the technical solution provided by the present invention improves the identification rate of the label, and on the other hand, can also improve the card reading efficiency of the reader.

Description

technical field [0001] The invention belongs to the field of radio frequency identification, and in particular relates to a card reading method and device for a radio frequency identification reader and a computer-readable storage medium. Background technique [0002] Radio frequency identification (Radio Frequency IDentification, RFID) technology, as a new technology of automatic identification, is widely used in many fields such as warehouse logistics, indoor positioning and book management by virtue of its many advantages. RFID uses radio frequency to carry out non-contact two-way communication to exchange data to achieve the purpose of identification. However, when more than one RFID tag communicates with the reader at the same time, since the tags of the passive RFID system share a transmission channel, the collision between the tags will cause the tag to fail to communicate with the reader normally. Therefore, how to improve the card reading efficiency of the reader i...
