I wonder what AI tech is being developed around detecting pin code entry on phones using passive CCTV networks.

If you process the feeds for public transit security cameras, I wouldn't be surprised if you can read the pin codes for a huge swath of the population. It would also reduce the need for law enforcement to try to get a suspect to tell them their passcode. Just look up that time they rode the subway 3 weeks ago and watch them enter it.

I often notice this at gas pumps. There are always cameras at gas pumps. If you pay at the pump, then you enter your pin. I shield mine very carefully, but I watch other people and they just punch in their pin without shielding. It's weird because people often shield their pin at a checkout counter because the clerk is right there (sort of) watching. Maybe these people feel at gas pumps, no one is watching... but the CCTV definitely is watching.

And as someone who has worked as a cashier, it is BLATANTLY obvious when someone's pin is 1111 or 1234. No matter how hard they try to shield it.

But it's not enough to know someone's code. So what if you do? Unless you can get the physical card without the owner knowing, what good would it do you?
