Don’t worry, this isn’t one of those frustrating Magic Eye pictures: it’s a close-up of a security hologram such as those on your credit card or passport.

Faking them isn’t impossible, however, which is why you’re advised to update your passport and credit cards every few years to improve your chances of staying one step ahead of the forgers.
