Holographic HDP Film consists of three layers to deliver the ultimate in card security: a top protective coating layer, a middle metalized holography layer with high-secure covert and forensic Visual Security Elements (VSEs), and a bottom High Definition Printing layer. These layers protect against the manipulation of printed data on a card. When combined with the reverse imaging capabilities of a Fargo HDP Series Card Printer/Encoder, the result is one of the most formidable visual security solutions available.
