<p>Provided is a product sales system with which a purchasing action by a customer is simplified. This product sales system builds a product sales system comprising: a portable terminal which is capable of reading in a 2-D code; a member information administration server which administers information relating to a pre-registered member; an authentication server which converts into a 2-D code information (billing information) relating to billing which is queried when purchasing a product; and a display device which displays the 2-D code. The portable terminal reads in the displayed 2-D code and acquires billing code information which is included in the 2-D code, and, when reading in a product 2-D code which includes information of a product for which a purchase is desired, generates purchasing information with which a product ID which is denoted in the product 2-D code is associated with the billing code information, and supplies same to the member information administration server. When the purchasing information is received over a network, the member information administration server verifies the purchase of the product corresponding to the product ID which is included in the purchasing information.</p> |
