A method of retrieving contact details using a print medium is disclosed. Data encoded on a surface of the print medium is sensed using a sensor module. 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. The print media identifier and the position of the sensor module relative to the surface of the print medium are determined from the sensed data. Contact details referenced by the print media identifier and the position of the sensor module are then retrieved from a database.
