Abstract: A method and system as presented by which valuable documents such as checks, deeds, driver's licenses, and other types of valuable documents can be imprinted with encoded symbols by a printer whereupon multiple assemblages of data can be imprinted on the valued document which is then susceptible to readout by a document reader which will automatically authenticate and verify the originator or the document and its authenticity and obviate any attempts for fraudulent alteration.

Abstract: A method and apparatus are used to provide quality assurance for the electronic transfer of document image files, for example, between banks. The documents may be, in the case of a bank, negotiable instruments, checks, deposit slips or other transactional documents. The document image file contains an image tag file and associated image data file. An image tag file contains first quality assurance data. An image data file contains second quality assurance data. The quality assurance data may be a MICR line from the document. A first reader extracts the first quality assurance data from the image tag file. A second reader reads the second quality assurance data from the image data file. A comparator receives the first and second sets of quality assurance data from the first and second readers and compares the first and second sets of quality assurance data to find correspondence between the data.

Abstract: A laser scanner is disclosed which is especially adapted as a label reader for point-of-sale data processingsystems. The scanner produces a polyphase scan pattern. The scanning beam is vertically deflected as a sinuosoidal function of time by an oscillatory mirror and is horizontally deflected as a sawtooth function of time by a rotary multifaceted mirror. The return light signal follows an optical path including the rotary multifaceted mirror which causes "derotation" of the image before it impinges upon the receiving photodetector. Additionally, the ambient or background light is reduced by providing an optical slit in the receiving optics so that the vertical deflection is accommodated.
