A method of communicating devices using virtual buttons, comprising:

• transmitting, by a user device, a store code to a server storing a plurality of sets of virtual buttons and a plurality of store codes, each set of the plurality of sets of virtual buttons corresponding to a respective store code;
• receiving, by the user device, a set of virtual buttons corresponding to the transmitted store code from the server, wherein each virtual button of the set of virtual buttons has a corresponding service request and the set of virtual buttons comprises one or more service requests to be transmitted to a staff device, the virtual buttons including a virtual button for requesting a bill, a virtual button for calling a staff, a virtual button for requesting a menu, and a virtual button for ordering food;
• providing, by the user device, an interface configured to receive a location identifier and button selection input selected by a user among the set of virtual buttons received from the server, and transmitting, by the user device, the location identifier and the button selection input to the server so that the server can transmit the location identifier and the button selection input to the staff device;
• and
• after the user device receives the button selection input selected by the user, changing, by the user device, a virtual button selected by the user until the user device receives from the staff device a confirmation of receipt of a service request corresponding to the virtual button selected by the user in a state that both the virtual button selected by the user and the virtual buttons are not selected are simultaneously displayed on the interface provided by the user device, and displaying, on at least a part of the virtual button selected by the user among the set of virtual buttons, a status of a requested service corresponding to the virtual button selected by the user according to a response of the staff device to the service request corresponding to the virtual button selected by the user.

A system for communicating devices requesting a service using virtual buttons, comprising:

• a user device including a processor configured to:
• transmit a store code to a server and receive a set of virtual buttons corresponding to the store code from the server, wherein the server stores a plurality of sets of virtual buttons and a plurality of store codes, each set of the plurality of sets of virtual buttons corresponding to a respective store code, wherein each virtual button of the set of virtual buttons has a corresponding service request and the set of virtual buttons comprises one or more service requests to be transmitted to a staff device, the set of virtual buttons including a virtual button for requesting a bill, a virtual button for calling a staff, a virtual button for requesting a menu, and a virtual button for ordering food,
• provide an interface configured to receive a location identifier and button selection input selected by a user among virtual buttons received from the server,
• transmit the location identifier and the button selection input to the server so that the server can transmit the location identifier and the button selection input to the staff device, and
• after the user device receives the button selection input selected by the user, change a virtual button selected by the user until the user device receives from the staff device a confirmation of receipt of a service request corresponding to the virtual button selected by the user in a state that both the virtual button selected by the user and virtual buttons that are not selected are simultaneously displayed on the interface provided by the user device, and display, on at least a part of the virtual button selected by the user among the set of virtual buttons, a status of a requested service corresponding to the virtual button selected by the user according to a response of the staff device to the service request corresponding to the virtual button selected by the user.
