Newest Canadian Passport Features Hidden Images Only Visible Under UV Light
The latest Canadian passport design, which was released in 2013, features amazing images that glow under UV light. The images are only vaguely visible in a daylight, but once you turn on a UV light, the beautiful sparkling images on the passport glow with energy.
Along with a biometric chip, these fascinating glowing images are security measures that help make it practically impossible to duplicate and falsify the passport.
