A system for transferring digital information to spatially localizable portable electronic devices has a plurality of portable electronic devices, with each portable electronic device supporting wireless communication. A spatial localizing module determines spatial location with submeter precision for each of the plurality of electronic devices, and a communication module is connected to the spatial localizing module for mediating wireless communication between the portable electronic devices. A user can define electronic data transfers between portable electronic devices in user determined spatial locations with submeter precision. Data transfers are possible to adjacent electronic devices, electronic devices within a defined radius, electronic devices along a defined bearing or having specific orientations, or even located within a defined set of regions or rooms.
