In an unmanned retail shop system, an user side information terminal, a retail shop side information terminal, and a settlement agency side information terminal are connected with each other through a network. The user side information terminal has not only means for selecting goods to be purchased and for transmitting information of the purchased goods to the retail shop side information terminal but also means for transmitting information of settlement account thereto. The retail shop side information terminal has a container for containing goods. The retail shop side information terminal further has means for transmitting, to the settlement agency side information terminal, not only information of request of drawing the money charged for the purchased goods but also information of request of transferring the money into the retail shop's account. The settlement agency side information terminal has not only means for making a secret number for opening the key of the container in which the purchased goods are contained but also means for transmitting the secret number both to the user side information terminal and to the retail shop side information terminal.
