System, shelf device, and cart pos

A shelf device provided for each of commodities in a shelf on which the commodities are displayed, the shelf device comprising:

• a first sensor configured to detect whether or not the commodity is taken out from the shelf;
• a first biological sensor provided to correspond to the first sensor and configured to read bioinformatics data for identifying a person;
• and
• a transmitter configured to correlate a commodity code for identifying the commodity when the first sensor detects that the commodity is taken out and bioinformatics data of the person is read by the first biological sensor, and to transmit the commodity code and the bioinformatics data to a cart point of sale (POS).

A cart point of sale (POS) that is movable, and configured to store commodities displayed on a shelf, the cart POS configured to receive a commodity code and bioinformatics data from a shelf device provided for commodities in the shelf on which the commodities are displayed, the shelf device including a first sensor configured to detect whether or not a commodity is taken out from the shelf, a first biological sensor provided to correspond to the first sensor and configured to read bioinformatics data for identifying a person, and a transmitter configured to correlate and transmit the commodity code for identifying the commodity when the first sensor detects that the commodity is taken out and the bioinformatics data of the person is read by the first biological sensor,

• the cart POS comprising:
• a storage section configured to store commodities;
• a second biological sensor configured to read the bioinformatics data of the person;
• a first memory configured to store, the bioinformatics data of the person read by the second biological sensor;
• a controller configured to determine reception of the commodity code and the bioinformatics data transmitted from the shelf device;
• and
• a second sensor configured to detect that a commodity is stored in the storage section,
• the controller configured to, when the second sensor detects that the commodity is stored, execute registration processing based on the commodity code, the reception of which is determined, on condition that the bioinformatics data, the reception of which is determined by the controller, and the bioinformatics data stored in the memory coincide.
