RFID tag scanning identification method and system

Abstract

The invention relates to a radio frequency identification device (RFID) label scanning recognition method. The method comprises the steps of scanning and reading of a RFID label arranged on a product entering a link by label scanning equipment of a link platform at the current link; extracting a corresponding link code according to a scanned and read RFID label code, wherein the link code comprises a link position and a link information position; verifying processing conditions at a previous link according to the link code, if verification is passed, writing the link code of the link into the RFID label through the label scanning equipment so as to cover an original link code; inquiring product information by reading the RFID label at an inquiry terminal, and simultaneously inquiring a local data base or a unified platform for product information corresponding to a to-be-inquired link by a link information platform of the link according to the to-be-inquired link; and returning the inquiry result into the inquiry terminal for processing. The invention further relates to a RFID label scanning recognition system. By means of the RFID label scanning recognition system, label information can be managed uniformly, and accordingly, the waste and the cost because of replacing RFID are reduced.

Description

technical field [0001] The present invention relates to radio frequency identification technology, in particular to a radio frequency identification (Radio Frequency Identification, referred to as RFID) label scanning identification method and system. Background technique [0002] In the use of traditional RFID tags, usually only the information of a certain link such as production, transportation, warehousing or sales is recorded, so when scanning the RFID tag, only the information of this link can be obtained, and the information of the previous link cannot be obtained. Since product information is only used in a certain process such as production, transportation, warehousing or sales, there is no or only a small amount of information available for the next link, which makes it impossible to query the complete process information of the product based on the scanned RFID label. [0003] When the product enters the next link, there is still the problem of electronic label re...

AI Technical Summary

Problems solved by technology

[0002] In the use of traditional RFID tags, usually only the information of a certain link such as production, transportation, warehousing or sales is recorded, so when scanning the RFID tag, only the information of this link can be obtained, and the information of the previous link cannot be obtained

Since product information is only used in a certain process such as production, transportation, warehousing or sales, there is no or only a small amount of information available for the next link, resulting in the inability to query the complete process information of the product based on the scanned RFID label

[0003] When the product enters the next link, there is still the problem of electronic label replacement. At present, traditional RFID labels are realized manually or by machines. By tearing off or removing the existing labels, pasting or fixing new labels, this will Will cause waste of RFID tags, and also involve related manpower or physical costs

In addition, the label type and encoding format of the labels used in each link may be different, which also increases the difficulty of management
