ForgeGuard Security Paper Inserts are sheets that we offer for Printable Parking Permits. These sheets are made of 7 mil thick Security White paper and use Luminary Technology that prevents photocopiers from exactly duplicating the print. When copying is attempted, a void message surfaces on black and white prints while color prints reveal validation upon being rubbed on with a coin. Parking permits printed on ForgeGuard Security Paper Inserts are virtually counterfeit-proof. We explain more about it in this video.
