1. A system for capturing an image of an optical code located at a region of interest in a document, the system comprising: a support for the document; a source of light, arranged to illuminate the document; a mount for supporting an imaging device at a position spaced from the document; a trigger for activating the imaging device to capture an image of the region of interest; means for automatically moving the mount and operating the trigger in dependence upon at least one coordinate identifying the region of interest, the coordinate being contained in a label stored in document parameters; and a decoder for the captured image to read the optical code.
