Methods and systems of determining the approximate location of a terminal are described herein. In one embodiment, a computer system receives from a first mobile computer terminal and/or from a communication system in communication with the first mobile computer terminal, global positioning satellite and/or cellular network location data, wherein the location data corresponds to the approximate location of the first mobile computer terminal. Based at least in part on the location data, the system determines if the first mobile computer terminal is within a first area, wherein presence in the first area is needed in order to be authorized to access a first service. The system, at least partly in response to failing to determine that the first mobile terminal is in the first area, transmits to the first mobile computer terminal location information regarding at least a first location in the first area.
