A system for retrieving contact details using a print medium is disclosed. A sensor module senses data encoded on a surface of the print medium is sensed using. The sensed data encodes a print media identifier which uniquely identifies the print medium, and a two-dimensional position with respect to the surface of the print medium. A processor determines from the sensed data the print media identifier and the position of the sensor module relative to the surface of the print medium. The processor then retrieves contact details referenced by the print media identifier and the position of the sensor module from a database.
