Panicking Over Suspicious Change? Here’s the Easiest Way to Spot Fake Bills Without Making It Awkward

Picture this: you’re buying snacks from a street vendor at night. You hand over a fifty-thousand bill and get your change. As you slip the money into your wallet, something feels off. The paper texture feels weird—maybe a little too smooth or too thin. Immediately, your heart skips a beat. "Wait, did I just get fake money?"

This happens more often than you'd think. Counterfeiters love taking advantage of dim lighting or situations where you’re in a rush, knowing you probably won't double-check your change.

We’ve all heard of the classic "Look, Feel, Tilt" method. It’s a timeless trick that still works perfectly. But to keep things casual so you don't look overly suspicious standing right in front of the cashier, you can use this quick technique:

1. First, just use your thumb to feel the texture as you grab the bill. Real money is made from cotton fibers, not standard paper. So it should feel slightly rough, especially around the printed numbers and the hero's portrait. This is because it’s printed using a special technique called intaglio. If it feels completely smooth and slick like printer paper, you definitely need to be suspicious.
2. Second, just give the bill a tiny tilt. On the newer, higher-denomination bills (like the 100k, 50k, and 20k), there’s a special ink that actually changes color depending on the angle you look at it. This is a high-level security feature that is incredibly hard to replicate with a regular printer.

As a company that processes billions of Rupiah daily, BGI operates under a much stricter standard. At our Cash Processing Center (CPC), the cash is sorted using advanced machines equipped with ultraviolet and magnetic sensors. Even bills with slight quality degradation are flagged, let alone fakes. So, any cash coming out of a BGI-managed ATM is 100% guaranteed authentic.

But for your daily transactions, your own attention is your best defense. Don't feel bad about checking your change. Taking two extra seconds to feel the bill is way better than going home empty-handed.
