alt Hacker NewsIt's not only at groceries stores, it's everywhere. For example at TSA security line and (sometimes) when boarding flights at the gate. You can (and should) exercise your right to opt-out every single time, before that right is taken away. Omg I sound like Richard Stallman... anyway, he was right all along.

Make sure to opt-out before handing your ID over to the agent. They will claim you can no longer opt-out at that point, even before scanning. I had one plead to my wife to go through, because they are being watched by management and it wouldn't look good.
I always say I'm opting out as loudly as possible, many people don't even know that you can opt-out. The signs are often small and out sight.
What really annoys me is when I politely decline the facial scan of TSA, and the agent makes some snide comment about my picture on my identification or something. And the next time it happens that I get a smart ass comment like that, I'm going to politely ask him if that's his opinion or was he told to say that.
I used to always opt out at TSA checkpoints. Then I decided that of all places, the airport makes the most sense to use biometrics. I mean, a human comparing my face to my ID is functionally equivalent.
What scares me about TSA using it is that it normalizes its use. Next it's at stadiums. Then Wegmans. If it would stop at airports, then I would be okay with it.
