Method, user terminal, and service terminal for processing service data

A computer-implemented method comprising:

• at a user terminal having one or more processors, a camera, memory and a wireless signal transceiver:
• capturing a service provider identifier embedded in a bar code adjacent a service terminal using the camera;
• detecting a service message through the wireless signal transceiver, the service message including the service provider identifier and service-related information;
• displaying the service provider identifier and the service-related information on a screen of the user terminal;
• in response to a user selection of the service-related information, generating and transmitting a first service purchase request message wirelessly to the service terminal using the wireless signal transceiver, the first service purchase request message including the service-related information and service-purchasing authorization information;
• and
• receiving, using the wireless signal transceiver, and displaying, on the screen, purchase confirmation message transmitted wirelessly from the service terminal.

A service terminal, comprising:

• one or more processors;
• memory;
• and
• one or more programs stored in the memory and to be executed by the one or more processors, wherein the service terminal is communicatively coupled to a remote server, the one or more programs further including instructions for:
• repeatedly broadcasting a service message through the wireless signal transceiver, the service message including a service provider identifier and service-related information;
• receiving a first service purchase request message wirelessly transmitted from a first user terminal adjacent the service terminal, the first service purchase request message including the service-related information and service-purchasing authorization information;
• in response to receiving the first service purchase request message:
• suspending the broadcast of the service message;
• transmitting the service-purchasing authorization information and the service provider identifier to the remote server;
• receiving a purchase confirmation message from the remote server;
• and
• wirelessly transmitting the purchase confirmation message to the first user terminal.
