METHOD, SERVER AND SYSTEM FOR PROVIDING CUSTOMIZED PRODUCT BY MEANS OF DECODING SECURITY-PROCESSED QR CODE

摘要

A method, performed in a decoding server and for providing a customized product by means of decoding a security-processed QR code, can comprise the steps of: receiving from a client a service request comprising identification information of the client and an encoded server-side message generated by means of primarily decoding a security-processed QR code in the client; extracting service information by means of secondarily decoding the server-side message; and determining, on the basis of the service information, whether or not the client satisfies a condition predetermined in the security-processed QR code.
