Prior arrangement information is automatically fetched in response to detection that a radio presence advertising mobile device of a user is disposed in a region of interest that is operatively adjacent to a transaction-processing location. The fetched information is used to automatically modify the transaction.

Associating prior arrangements with on-premise manual transactions and concomitant presence of actor's presence-advertising emitter in fine resolution region

A radio presence-advertising signal (PAS) a PAS emitter is simultaneously received at two or more co-located directional antennas that are coupled to respective radio receivers. The antennas have reception sensitivity lobes that overlap to define a region of interest at the overlap. Substantially cotemporaneous signal strength indications are obtained from the radio receivers. A difference signal representative of a difference between two of the obtained signal strength indications of the respective antennas is generated. An average signal representative of a running average of two or more of the obtained signal strength indications is generated and used to produce a normalized confidence indicator indicating a level of confidence that the PAS emitter is disposed inside (e.g., centered in) the region of interest or alternatively indicating a level of confidence that the PAS emitter is disposed outside the region of interest. Action is taken or avoided based on the confidence signal.

High confidence isolated presence detection in fine resolution region

The disclosure relates to technology for determining a location of a user in a physical venue, the method comprising receiving, at a central processor, a signal from a wireless transmitter in the user's possession, the signal containing an encoded message and additional metadata, determining a location of the wireless transmitter in the physical venue based on the encoded message and the additional metadata, and outputting the location.
