ABSTRACT:
A shopping system comprises a product item having an interface surface and a reading device for reading coded data disposed on the interface surface. The reading device includes: (a) a radiation source for emitting radiation which exposes a coded data portion on the interface surface; (b) an image sensor for sensing the exposed coded data portion; (c) a force sensor coupled to a nib of the reading device; and (d) a processor for determining product identity data and/or position data. The reading device is adapted to sense the coded data in response to contact between the nib and the interface surface.
