The present invention scans a near-field wireless communication device having a particular separation value, searches for the same in a DB server, automatically displays a menu order screen of a corresponding restaurant that matches the searched near-field wireless communication device information, and orders food if a client terminal executes an application around or in a restaurant; checks a table number using a distance sensor value, a beacon (Bluetooth 4.0 BLE) distance measurement value or a WiFi signal strength (RSSI) value and communicates the bill and a telephone number if the client terminal enters a pay counter after having a meal; and thereby has the effect of being able to conveniently complete order and payment processing without additional devices or means. |
