[0020] Referring to the attached drawing, it contains the following steps:
[0021] (1) The steps of establishing and storing commodity information;
[0022] The implementer of the present invention needs to transmit commodity information, such as commodity name, commodity model, commodity price, commodity picture, commodity color and other information to the server of the system. After the system receives the information, it will create a commodity file and store it in the system database.
[0023] (2) Steps of establishing and storing two-dimensional code group information: each two-dimensional code information is composed of a url address, and the url address includes a self-incrementing serial number and a check code generated by an encryption algorithm for the serial number to ensure two-dimensional The code has uniqueness and anti-counterfeiting ability, and the QR code group defines the range of the serial number and the key used by the encryption algorithm;
