Security ID cards with built-in holograms (w/ Video)
(PhysOrg.com) -- Plastic cards with security features are ubiquitous these days, having a wide variety of uses such as credit cards, employee cards, licenses, and so on. Many have holographic images, but they are relatively easy to tamper with. Now researchers at SABIC Innovative Plastics and GE Global Research have developed a new class of thermoplastic holographic materials that embed holograms within the plastic of cards, making them virtually impossible to copy or alter.
