摘要

The method involves determining position of a user through an integrated global positioning system (GPS) chip of a smartphone(RTM: high-end mobile phone) of a user by using GPS satellites (7). Data are collected from a national, departmental or communality data server (2) via wireless fidelity (WiFi)routers (8). The user is guided towards a product that is selected by the user, using the data by displaying directional arrows on a touch screen of the smartphone(RTM: high-end mobile phone) along with path mark indications. The routers retransmit the selected product choice to WiFior radio-frequency identification (RFID) transceivers.
