A method for communicating data representing spatially organized information, performed by a central server RF-frequency peripherals with locations within a predetermined area, each location being defined by a vertical and horizontal position within a plane perpendicular to a floor of the predetermined area, each location being associated with a corresponding unique identifier. The method may involve receiving a communication from a mobile terminal including a unique identifier received by the mobile terminal from an RF peripheral located in the predetermined area, determining a location of the mobile terminal within the predetermined area based on the location associated with the unique identifier, and transmitting to the mobile terminal spatially localized information associated with the location. The unique identifier may be particular to an RF peripheral including an antenna and an electronic chip configured for NFC to be activated by the mobile terminal when the peripheral is within a communication range.
