PhotoShieldTM Cover A clear patent pending license plate cover, incorporating a thin strip of lens on the inside. It looks just like a regular cover that you find in an automotive accessory shop. However, when a photo-radar camera mounted on the side of the road takes a picture of your tag WITH OR WITHOUT flash, 2 or 3 characters will be blurred due to the refraction caused by the lens. The resulting image is illegible. If one character is unreadable the ticket is technically unusable and discarded.
