Abstract:
The present invention can provide a method for inputting/outputting information about a QR code, comprising steps in which: a main server generates a link value having a random sub-domain or sub-folder (sub-directory) in a domain; the main server generates a QR code having the link value; a client terminal scans the QR code so that the main server and the client terminal are connected through the link value stored in the QR code; the main server determines whether the input information stored in the link value is present in the database; an information input window is displayed on the client terminal if the input information stored in the link value is not present; the information inputted from the client terminal is received so as to be stored in the database of the main server; and the input information stored in the link value is displayed on the client terminal if the input information stored in the link value is present in the main server.
