Thanks to an analog authentication process, the OptiKey verification system raises identification technology to a new level by creating a unique signature in a submicron optical master. The optical master signature is then embedded in the ID label. A perfectly matched optical structure found in the optical reader verifies the master signature in real time. According to the company, documents made using the system are impossible to counterfeit or copy. The reader is available in handheld and swipe-card system formats. Applications include credit cards, driver's licenses, optical ID labels, employee security cards, passports, and even currency. It also could be used to authenticate CDs, DVDs, and similar products.
