The sensing device is configured to detect displacement of a commodity item from a commodity display section. The one or more cameras are configured to capture images around the commodity display section. The processor is configured to track a location of each of one or more customers who is determined to have entered a first area around the commodity display section based on the captured images, and upon detection of the displacement of the commodity item by the sensing device, perform an operation to determine a purchasing customer of the commodity item based on the tracked location of each of the one or more customers, and cause purchase registration of the commodity item in association with an ID of the purchasing customer. ## Claims ### Claim 1 A transaction processing system, comprising: a sensing device configured to detect displacement of a commodity item from a commodity display section; one or more cameras configured to capture images of areas around the commodity display section; and a processor configured to: track a location of each of one or more customers who is determined to have entered a first area around the commodity display section based on the captured images; and upon detection of the displacement of the commodity item by the sensing device, perform an operation to determine a purchasing customer of the commodity item based on the tracked location of each of the one or more customers, and cause purchase registration of the commodity item in association with an ID of the purchasing customer. ### Claim 2 (depends on 1) The transaction processing system according to claim 1, wherein the processor is configured to determine, as the purchasing customer, a customer whose tracked location is closest to and within a predetermined distance from the commodity display section during a predetermined time period before the detection of the displacement of the commodity item. ### Claim 3 (depends on 1) The transaction processing system according to claim 1, wherein the processor is configured to assign a tracking ID to each of the one or more customers when the customer is determined to have entered a second area around the first area based on the captured images and track the location of the customer in association with the assigned tracking ID. ### Claim 4 (depends on 3) The transaction processing system according to claim 3, wherein there is no overlap between the first area and the second area. ### Claim 5 (depends on 3) The transaction processing system according to claim 3, further comprising: a user interface configured to perform an operation to receive a customer ID of a customer, the user interface provided in the first area, wherein the processor is configured to store the customer ID in association with a tracking ID assigned thereto. ### Claim 6 (depends on 3) The transaction processing system according to claim 3, wherein the processor is configured to stop tracking the location of each of one or more customers who is determined to have entered the first area when the customer is determined to have entered a third area around the second area. ### Claim 7 (depends on 6) The transaction processing system according to claim 6, wherein the processor is configured to cause settlement processing for the commodity item using payment information associated with the ID of the purchasing customer when the customer is determined to have entered the third area. ### Claim 8 (depends on 6) The transaction processing system according to claim 6, wherein there is no overlap between the second area and the third area. ### Claim 9 (depends on 1) The transaction processing system according to claim 1, wherein the processor is configured to stop tracking the location of each of one or more customers who is determined to have entered the first area when the tracked location of the customer is not updated for a predetermined period of time. ### Claim 10 (depends on 1) The transaction processing system according to claim 1, wherein the processor is configured to generate a first notification when the purchasing customer is not authenticated and a second notification when the purchasing customer is not determined through the operation, the second notification being different from the first notification. ### Claim 11 (depends on 1) The transaction processing system according to claim 1, wherein the sensing device is further configured to detect placement of the commodity item to the commodity display section, and the processor is configured to, upon detection of the placement of the commodity item by the sensing device, perform a second operation to determine a commodity-returning customer of the commodity item based on the tracked location of each of the one or more customers, and cause purchase deregistration of the commodity item in association with an ID of the commodity-returning customer. ### Claim 12 (depends on 11) The transaction processing system according to claim 11, wherein the processor is configured to generate a first notification when the purchasing customer is not authenticated, a second notification when the purchasing customer is not determined through the operation, and a third notification when the commodity-returning customer is not authenticated and when the commodity-returning customer is not determined through the second operation, the first, second, and third notifications being different from each other. ### Claim 13 (depends on 1) The transaction processing system according to claim 1, wherein the sensing device includes a weight scale. ### Claim 14 (depends on 1) The transaction processing system according to claim 1, further comprising: a projector configured to project a region image corresponding to the first area onto a floor. ### Claim 15 A method for processing a transaction using a sensing device configured to detect displacement of a commodity item from a commodity display section and one or more cameras configured to capture images of areas around the commodity display section, the method comprising: tracking a location of each of one or more customers who is determined to have entered a first area around the commodity display section based on the captured images; and upon detection of the displacement of the commodity item by the sensing device, performing an operation to determine a purchasing customer of the commodity item based on the tracked location of each of the one or more customers, and causing purchase registration of the commodity item in association with an ID of the purchasing customer. ### Claim 16 (depends on 15) The method according to claim 15, wherein a customer whose tracked location is closest to and within a predetermined distance from the commodity display section during a predetermined time period before the detection of the displacement of the commodity item is determined as the purchasing customer. ### Claim 17 (depends on 15) The method according to claim 15, further comprising: assigning a tracking ID to each of the one or more customers when the customer is determined to have entered a second area around the first area based on the captured images, wherein the location of each of the one or more customers is tracked in association with the assigned tracking ID. ### Claim 18 (depends on 17) The method according to claim 17, further comprising: performing settlement processing for the commodity item using payment information associated with the ID of the purchasing customer when the customer is determined to have entered a third area around the second area. ### Claim 19 (depends on 15) The method according to claim 15, wherein the sensing device is further configured to detect placement of the commodity item to the commodity display section, and the method further comprises, upon detection of the placement of the commodity item by the sensing device, performing a second operation to determine a commodity-returning customer of the commodity item based on the tracked location of each of the one or more customers, and causing purchase deregistration of the commodity item in association with an ID of the commodity-returning customer. ### Claim 20 (depends on 15) The method according to claim 15, further comprising: projecting a region image corresponding to the first area onto a floor.
