How to spot a fake id by the OVI shift quality

In today's guide on how to spot a fake id, let's talk about the OVI (Optically Variable Ink). Real OVI has a very smooth and distinct color shift—usually from gold to green. Many novelty id cards use a cheap iridescent ink that just looks rainbow-ish or silver from every angle.

To check this, hold the card flat and slowly tilt it away from you. The color should change cleanly at a certain point. If the color stays the same or if it looks like a grainy glitter, it is a fake. This is one of the most expensive features for vendors to replicate, so it's a great way to verify the quality of your card before you use it.
