Every one of us has walked through those shop security gates and had that split second of doubt.
What actually sets them off?
Inside a security tag there’s no battery, no chip, and no intelligence — just a tiny tuned circuit designed to interact with the electromagnetic field between the gates.
In this video I break down exactly how shop security alarms work, why that small device is enough to trigger them, and why this simple piece of engineering is far more clever than it looks. I inadvertently end up telling you how to fool their security measures... oops!
Once you understand it, you’ll never walk through those gates the same way again.
