PROBLEM TO BE SOLVED: To provide an inventory control system capable of inputting information easily and being constructed at low cost.SOLUTION: The inventory control system is formed of a refrigerator, a radio module, and a server device communicating with the radio module. The radio module comprises: a radio communication part; a power supply part; a period specification button for specifying start timing of a storage period of food products; and an attribute specification part for indicating a food product attribute of the radio module. The server device manages inventory of food products stored in the refrigerator based on the attribute specification part of the radio module and delivered date information specified by the period specification button, when the period specification button is pushed. Thereby, the radio module is added to the food products and then is stored in the refrigerator, and by pushing the period specification button, the food product attribute and the food product delivery period information can be transmitted and inputted to the server. In addition, a user prepares plural pieces of the radio modules having the food product attribute, thereby an inventory control system can be constructed with a simple structure without complicated equipment and a refrigerator with facility. |
