A merchandise sales system that simplifies the purchase action of the customer is provided. This merchandise sales system constructs a merchandise sales system provided with: a portable terminal capable of reading a two-dimensional code; a member information management server that manages preregistered information related to a member; an authentication server that converts information related to billing referred to when a commodity is purchased (billing information) into a two-dimensional code; and a display device that displays the two-dimensional code. The portable terminal reads the displayed two-dimensional code and obtains billing code information included in the two-dimensional code, and when a commodity two-dimensional code including information on a commodity to be purchased is read, generates purchase information in which a commodity ID indicated by the commodity two-dimensional code and the billing code information are associated with each other and supplies it to the member information management server. When the purchase information is received through a network, the member information management server confirms purchase of the commodity corresponding to the commodity ID included in the purchase information. |
