Abstract: A system for processing beacon-based mobile transactions in food and beverage establishments. A ticket for a restaurant customer is automatically generated upon the customer's physical entry into a trusted transaction environment in a restaurant point of sale system (POS) via a mobile application executing on a user device in communication with an application server. The trusted transaction environment corresponds to a virtual perimeter defined by one or more beacons. In an embodiment, a user provides a service worker at the merchant establishment with the user's ticket ID to associate the user's ticket in the POS system. When the user is ready to leave the merchant establishment, the ticket may be paid manually by the user via a graphical user interface, or the user may exit the trusted transaction environment and the system will automatically pay and close the ticket at a predefined interval upon existing the trusted transaction environment.
