Abstract
The present invention provides a durable and self-verifying secure document system and a method for its production, wherein counterfeiting is prevented. The secure document system is potentially useful for a wide variety of documents including, but not limited to, lottery tickets, currency, traveler's checks, passports, stock and bond certificates, bank notes, driver's licenses, wills, coupons, rebates, contracts, food stamps, magnetic stripes, test answer forms, invoices, tickets, inventory forms, tags, labels and original artwork. The instant invention provides a plastic paper substitute having various indicia associated therewith including visible and hidden indicia. Application of the hidden indicia to the plastic paper substitute is implemented in accordance with a computer software program, and the document includes an integral lens area which is particularly designed to verify the document's authenticity by rendering the hidden indicia visible to the viewer. The instant invention is particularly durable when produced on one of the modern plastic paper substitutes.
