COMMODITY QR CODE IDENTIFICATION-BASED INTERACTIVE TRANSACTION SERVICE METHOD AND SYSTEM

摘要

A commodity QR code identification-based interactive transaction service method and system. Said method comprises: 1) displaying, on a service platform (2), commodities of a merchant terminal (3); 2) when a client (1) selects a certain commodity (31) on the service platform, setting a QR code (4) for the selected commodity (31), and sending the QR code (4) to the merchant terminal (3) corresponding to the selected commodity (31) by means of the service platform (2); 3) after the merchant terminal (3) receives the QR code (4), taking the QR code (4) as an identity symbol of the selected commodity (31), and making the QR code (4) to be appended to the selected commodity (31), so as to form a commodity QR code (41) of the selected commodity (31); 4) when the merchant terminal (3) sends the selected commodity (31) to the client (1), the client (1) determines whether the commodity QR code (41) of the received selected commodity (31) is the same as the QR code (4) sent by the client (1), if the commodity QR code is the same as the QR code (4) sent by the client (1), the commodity of the client (1) being regarded as the selected commodity (31) of the client (1), otherwise, the commodity being not regarded as the selected commodity (31) of the client (1). Said method can ensure that the commodity received by the client (1) is the commodity (31) selected by the client (1), avoiding counterfeit commodities.
