PROBLEM TO BE SOLVED: To provide contactless document scanning using portable scanners, in systems, methods, apparatus, and user-interfaces consistent with embodiments. SOLUTION: A magnetic field sensor may use variations in a known magnetic field and may provide information related to the orientation of a portable scanner relative to an image on a medium being scanned. The orientation information provided by the magnetic field sensor may be used to determine the orientation of a scanner when the sensory threshold of motion sensors on the portable scanner has been exceeded.
