A geo-fencing system includes a plurality of beacons defining zones within a venue. The system receives a first beacon identifier from a mobile device and registers the mobile device in a first zone corresponding to the first beacon. The system causes a first menu to be displayed on the mobile device, indicating options for the first zone. In response to selection of one of the options, the system registers the mobile device as being active in the first zone. The system then receives a second beacon identifier and registers the mobile device as being in the second zone. The system also suspends the activity of the mobile device in the first zone and causes options to be displayed to continue or terminate the activity in the first zone.
