Abstract: A device for automatically reading checks, wherein a scanner includes a reading unit for reading an identification code on the check, and a reading unit for taking an image of the surface of the check, and the device also includes a central processing unit receiving the digitized image of the check, and for defining an the image, on the basis of the identification code, at least two subimages respectively containing the numeric amount and the alphabetic amount of the check. The device also provides for binary-coding the subimages to automatically read the numeric and alphabetic amounts in the binary-coded subimages, and for correlating the two amounts to elect a final amount, which is displayed on a video of the processing unit together with the image of the check.
