Abstract
A product management device includes: a reception state storage unit configured to, on the basis of changes in reception states of signals transmitted from tag devices attached to products, store identification information of products in which the changes have occurred; and a list output unit configured to output a list of products for which the changes in the reception states are equal to or greater than a threshold value.
Claims5
A product management device comprising:
- a computer;
- and
- a memory storing executable instructions that, when executed by the computer, causes the computer to perform as:
- a reception state storage unit configured to, on the basis of changes in reception states of signals transmitted from tag devices attached to products, store identification information of products in which the changes have occurred;
- and
- a list output unit configured to output a list of products for which the changes in the reception states are equal to or greater than a threshold value,
- wherein the reception state storage unit stores the identification information of the products in which the reception state changes have occurred when a product purchaser enters a store.
A method of controlling a product management device including a reception state storage unit configured to, on the basis of changes in reception states of signals transmitted from tag devices attached to products, store identification information of products in which the changes have occurred, and a list output unit configured to output a list of the products, the method comprising:
- controlling the list output unit such that a list of the products for which the changes in the reception states are equal to or greater than a threshold value is output,
- wherein the reception state storage unit stores the identification information of the products in which the reception state changes have occurred when a product purchaser enters a store.
A non-transitory computer-readable recording medium storing a program causing a computer of a product management device to perform process, the product management device including a reception state storage unit configured to, on the basis of changes in reception states of signals transmitted from tag devices attached to products, store identification information of products in which the changes have occurred, and a list output unit configured to output a list of the products, the process comprising:
- controlling the list output unit such that a list of the products for which the changes in the reception states are equal to or greater than a threshold value is output,
- wherein the reception state storage unit stores the identification information of the products in which the reception state changes have occurred when a product purchaser enters a store.
