Abstract
A device for analyzing information carriers, particularly gaming coupons or receipts, includes a carrier receiver device, an image scanning device for reading the information on the carrier, a processing unit for processing the image information and for transmitting the information to a central gaming management unit. The carrier is printed with multiple colors. The image scanning device includes an optical reader which is blind to a single color, but sensitive to all other colors. The carrier has fixed marking patterns, printed in the color to which the image scanning device is blind, which delineate where the player marks the carrier with variable gaming information. The carrier also has fixed information for alignment and type designation printed in other colors. The processing unit uses stored marking patterns corresponding to the type of carrier analyzed, by superimposing blind color information.
