In one method according to the invention, a security document of an undetermined size within a range of sizes is processed by capturing images corresponding to a topside and bottomside thereof sufficient to encompass the largest possible sized document and then searching through the captured image data to locate an identification code which may have been formed on any location of the document. If a symbol is found that satisfies a predetermined criteria for being an identification code, then the symbol is decoded, and the identification code for the document is utilized to control further processing of the document. Further processing subroutines of the document may include subroutines which utilize one or multiple imaging systems to verify that the document is authentic, subroutines for validating the document, and subroutines for voiding the document.

1. A method for determining authenticity of a lottery game ticket having at least one play area including scratch-off material defining outer and indicia icon surfaces, said method comprising the steps of:incorporating a light sensitive additive into said lottery game ticket, said light sensitive additive emitting light in a second band of wavelengths when illuminated in a first band of wavelengths, said additive being selected from the group consisting of luminophor additives and phosphor additives; illuminating said lottery game ticket using a light source emitting light in said first wavelength band; imaging said game ticket to capture image data representing said game ticket as seen illuminated by said first band of wavelengths; and analyzing said captured image data to determine if said image data indicates the presence of said additive incorporated in said game ticket.
