    摘要: A shopping path tracking system is disclosed that comprises a terminal device, a fixed communication device, and a path management device. The fixed communication device wirelessly communicates with the terminal device, calculates a response time of the terminal device, and reports the calculated response time to the path management device. The path management device detects a position of the terminal device based on the response time reported from the fixed communication device, stores the detected position, and detects a travel path of the terminal device by tracking the stored positions.
