What is this camera like thing on electronic shop price tags? (And how does it work)

I first thought it was a camera but there was no point, After some searching I found that these things could communicate optical,, so that might be it, if so how do they work?

Or is human. Hard to tell anymore. Welcome to the post truth world!
