Self-POS system, self-POS terminal apparatus, control method, and non-transitory computer readable medium storing control program
A self-POS system ( 1 ) according to the present disclosure is a self-POS system whereby a customer registers a commodity and checks out and includes a sensor ( 2 ) that detects that the customer has retrieved the commodity in a display state, an imaging apparatus ( 3 ) that images the customer, and a control unit ( 4 ) connected the sensor ( 2 ) and the imaging apparatus ( 3 ). The control unit ( 4 ) is configured to record, as a problem image, an image including at least an image at the time of the retrieval of the commodity when the commodity detected by the sensor ( 2 ) as having been retrieved is not registered. Thus, it is possible to provide a self-POS system, a self-POS terminal apparatus, a control method, and a control program capable of recording a fraudulent act at the time of check-out.
1. A self-POS system for a customer to register a commodity and check out, the self-POS system comprising:
a sensor configured to detect that the customer has retrieved the commodity in a display state;
an imaging apparatus configured to image the customer; and
a control unit connected to the sensor and the imaging apparatus, wherein
the commodity is placed on a commodity shelf, the self-POS system includes a weight sensor provided on the commodity shelf as the sensor, and a self-POS terminal apparatus for executing registration processing and check-out processing of the commodity is provided on the commodity shelf,
the retrieval of the commodity is detected by the weight sensor, and the control unit is configured to identify the retrieved commodity based on a decreased value of a weight and store a possible commodity as a retrieved commodity candidate in a commodity list,
when it is not possible to identify which commodity the retrieved commodity is, the control unit is configured to store a plurality of possible commodities in the commodity list as possible retrieved commodity candidates,
when the retrieved commodity is registered, the registered commodity is deleted from the commodity list, and when the registered commodity is registered in the commodity list as one of the possible retrieved commodity candidates, the control unit is configured to delete the registered commodity and other possible commodities from the commodity list, and
when all the commodity candidates are not deleted from the commodity list, the control unit is configured to record, as a problem image which is a fraudulent act where the customer has retrieved the commodity but has not registered the commodity, an image including an image of the customer at a time of the retrieval of the commodity.
2. The self-POS system according to claim 1 , wherein
the control unit is configured to record, as the problem image, the image including the image at the time of the retrieval of the commodity when the commodity is not registered within a predetermined time after the detection by the sensor that the customer has retrieved the commodity.
3. The self-POS system according to claim 2 , wherein
the control unit starts controlling the imaging apparatus to perform the imaging when the sensor detects the customer retrieving the commodity and to end the imaging when the predetermined time has elapsed.
4. The self-POS system according to claim 1 , wherein the control unit is provided in the self-POS terminal apparatus.
5. The self-POS system according to claim 2 , wherein the control unit is provided in the self-POS terminal apparatus.
6. The self-POS system according to claim 3 , wherein the control unit is provided in the self-POS terminal apparatus.
7. The self-POS system according to claim 1 , further comprising a management apparatus, wherein
the control unit is provided in the management apparatus.
8. The self-POS system according to claim 2 , further comprising a management apparatus, wherein
control unit is provided in the management apparatus.
9. The self-POS system according to claim 3 , further comprising a management apparatus, wherein
the control unit is provided in the management apparatus.
10. A method of controlling a self-POS system for a customer to register a commodity and check out comprising a sensor configured to detect that the customer has retrieved the commodity in a display state, an imaging apparatus configured to image the customer, and a control unit connected to the sensor and the imaging apparatus, the method comprising:
detecting the retrieval of the commodity by the weight sensor;
identifying the retrieved commodity based on a decreased value of a weight and storing a possible commodity as a retrieved commodity candidate in a commodity list;
when it is not possible to identify which commodity the retrieved commodity is, storing a plurality of possible commodities in the commodity list as possible retrieved commodity candidates;
when the retrieved commodity is registered, deleting the registered commodity from the commodity list, and when the registered commodity is registered in the commodity list as one of the possible retrieved commodity candidates, deleting the registered commodity and other possible commodities from the commodity list; and
when all the commodity candidates are not deleted from the commodity list, recording, as a problem image which is a fraudulent act where the customer has retrieved the commodity but has not registered the commodity, an image including an image of the customer at a time of the retrieval of the commodity, wherein
the commodity is placed on a commodity shelf, the self-POS system includes a weight sensor provided on the commodity shelf as the sensor, and a self-POS terminal apparatus for executing registration processing and check-out processing of the commodity is provided on the commodity shelf.
11. A non-transitory computer readable medium storing a control program for causing a computer to operate as a control unit of a self-POS system for a customer to register a commodity and check out, the self-POS system comprising a sensor configured to detect that the customer has retrieved the commodity in a display state, an imaging apparatus configured to image the customer, and the control unit connected to the sensor and the imaging apparatus, the control program comprising:
detecting the retrieval of the commodity by the weight sensor;
identifying the retrieved commodity based on a decreased value of a weight and storing a possible commodity as a retrieved commodity candidate in a commodity list;
when it is not possible to identify which commodity the retrieved commodity is, storing a plurality of possible commodities in the commodity list as possible retrieved commodity candidates;
when the retrieved commodity is registered, deleting the registered commodity from the commodity list, and when the registered commodity is registered in the commodity list as one of the possible retrieved commodity candidates, deleting the registered commodity and other possible commodities from the commodity list; and
when all the commodity candidates are not deleted from the commodity list, recording, as a problem image which is a fraudulent act where the customer has retrieved the commodity but has not registered the commodity, an image including an image of the customer at a time of the retrieval of the commodity, wherein
the commodity is placed on a commodity shelf, the self-POS system includes a weight sensor provided on the commodity shelf as the sensor, and a self-POS terminal apparatus for executing registration processing and check-out processing of the commodity is provided on the commodity shelf.
