Abstract

[Project] To provide a system that enables the unmanned sale of food items, such as fresh food or lunch boxes, in an unmanned vending machine in which items for sale are housed in a case. [Solution] The unmanned sales system (100) of the present disclosure is a system for managing the unmanned sales of food to purchasing users. The unmanned vending machine (500) transmits to the server (300) operation information regarding the locking and unlocking operation of the door part (520) by the electronic lock (550) and state detection information regarding the temperature inside the case (510) detected by the state detection device (570) and the state of the unmanned vending machine (500). The server (300), which transmits to the unmanned vending machine (500) a command to perform unlocking of the door part (520) by the electronic lock (550) based on user authentication, transmits to the unmanned vending machine (500) a command to prohibit unlocking of the door part (520) by the electronic lock (550) based on a predetermined sales period for the food contained in the unmanned vending machine (500).
