One or more coating layers may be disposed on the surface of the transparent laminar. Printed indicia on the upper surface of the form is not readable unless the transparent lamina is physically separated from the scrambling layer or if the scrambling layer is optically altered or negated. The coating layers may reveal tamper evidence if a surreptitious attempt of obtaining the printed indicia is made by physical, mechanical, electronic and/or chemical means without removing the separating the transparent lamina and the scrambling layer. | 09-24-2009 |
