INTERACTIVE HANDHELD SCANNER

A swipe scanner for scanning a graphic image pre-printed on a surface. The swipe scanner comprises: (a) a printhead for printing a position-coding pattern onto the graphic image, the position-coding pattern identifying a plurality of absolute positions and an impression identity for the graphic image; (b) an ink supply containing an ink for printing the position-coding pattern; (c) a first sensor for sensing positions of the scanner during a swipe of the surface; (d) a second image sensor for capturing, during the swipe, portions of the graphic image; and (e) a processor. The processor is configured for: using the sensed positions to control an output of the printhead during the swipe; using the sensed positions to assemble the captured portions of the graphic image into a scanned graphic image; and generating association data indicating an association between the impression identity, the plurality of absolute positions and the scanned graphic image.
