Methods for geographic gesturing using a mobile device for interactions with nearby other mobile devices

A method of transaction processing, comprising:

• obtaining geogesture parameters based on a geogesture an initiator device of an initiator, wherein the geogesture comprises an orientational movement of the initiator device in a geographical location of the initiator device;
• computing a geogesture area based at least part on the geogesture parameters, wherein the geogesture area corresponds to a geographical area in the geographical location based on the geogesture;
• determining a geographical offset of the initiator device in the geographical location based at least part on the geogesture area and the geogesture parameters;
• adjusting the geogesture area to include the geographical offset of the initiator device;
• querying a POI database system for a matching set of POIs, wherein a POI of the matching set of POIs is a matching POI matching the geogesture area when a POI location of the POI is at least partly within the geogesture area and meets a matching requirement;
• providing the matching set of POIs, or information thereof, to the initiator device or a designee;
• identifying a selected POI from the matching set of POIs;
• identifying a potential respondent device of a potential respondent associated with the selected POI;
• determining whether the potential respondent is to proceed with a transaction with the initiator and be a respondent, wherein the respondent interacts via a respondent device;
• obtaining transaction details from the initiator device, the respondent device, or both;
• and
• processing the transaction.
