How to spot a fake id by the material 'ping' sound

In this guide on how to spot a fake id, let's talk about the 'ping' test. Real IDs from states like New York or California are made of layers of polycarbonate that are fused together. When you drop a polycarbonate card on a hard surface, it should make a high-pitched, metallic 'ping' sound, similar to a piece of ceramic.

If your novelty id card makes a dull 'thud' sound, it's likely made of PVC or a cheap laminate. Bouncers use this trick often—they'll drop the card on the bar or flick it with their finger to hear the resonance. If it doesn't sound right, they'll know it's a fake. Always ask your vendor for polycarbonate material if you want to pass this test.
