6. The store system according to claim 5 , further comprising:

a customer service support unit configured to transmit customer service support information to the store clerk terminal based on the event information, wherein

the customer service support unit is configured to, in response to a plurality of pieces of event information indicating that the visitor terminal enters the predetermined area being generated by the visitor terminal, transmit the customer service support information to the store clerk terminal.

7. The store system according to claim 6 , wherein

the customer service support unit is configured to transmit the customer service support information to a wearable display worn by the store clerk.

8. The store system according to claim 1 , wherein

the status determination unit is configured to update the status corresponding to the event information based on a time of leaving the predetermined area.

9. The store system according to claim 1 , wherein

among the acquired first position information and second position information, only the acquired first position information and second position information at the detection time of the first event is stored as the event information.

10. A status determination method, comprising:

acquiring first position information of a radio frequency identifier (RFID) medium attached to an item and second position information of a visitor terminal carried by a visitor;

detecting an event that the RFID medium or the visitor terminal enters or leaves a predetermined area in a store space based on the acquired first position information and second position information;

storing event information of the item including an identifier (ID) that identifies the RFID medium, information about the predetermined area based on the acquired first position information and second position information, and a detection time of the event and event information of the visitor including an identifier (ID) that identifies the visitor terminal, information about the predetermined area based on the acquired first position information and second position information, and a detection time of the first event; and

determining a state of the item or a status of the visitor, which is an action content, the state of the item referring to whether i) the item was taken out, ii) the item was returned, iii) a price of a tag of the item was confirmed, or iv) the item was purchased, and the action content of the visitor referring to whether v) the visitor is passing by the item, vi) the visitor is staying in the predetermined area, vii) the visitor is taking out the item, viii) the visitor is confirming the price of the tag of the item, ix) the visitor is returning the item, or x) the visitor is trying on the item, based on an association between the event information of the item and the event information of the visitor.

11. A non-transitory computer-readable medium storing a program that is capable of being executed by a computer in a store system, wherein the program causes the computer to execute instructions for:

acquiring first position information of a radio frequency identifier (RFID) medium attached to an item and second position information of a visitor terminal carried by a visitor;

detecting an event that the RFID medium or the visitor terminal enters or leaves a predetermined area in a store space based on the acquired first position information and second position information;

storing event information of the item including an identifier (ID) that identifies the RFID medium, information about the predetermined area based on the acquired first position information and second position information, and a detection time of the event and event information of the visitor including an identifier (ID) that identifies the visitor terminal, information about the predetermined area based on the acquired first position information and second position information, and a detection time of the first event; and

determining a status, which is a state of the item or is an action content of the visitor, the state of the item referring to whether i) the item was taken out, ii) the item was returned, iii) a price of a tag of the item was confirmed, or iv) the item was purchased, and the action content of the visitor referring to whether v) the visitor is passing by the item, vi) the visitor is staying in the predetermined area, vii) the visitor is taking out the item, viii) the visitor is confirming the price of the tag of the item, ix) the visitor is returning the item, or x) the visitor is trying on the item, based on an association between the event information of the item and the event information of the visitor.
