On Android you can use Google Lens or, if you don’t want to use Google products, any random QR code scanner app.

No idea about iPhone as I’ve never owned one, but I’d assume most QR code scanners can do that there as well.

Whenever I hear someone say that something is impossible with current technology, I think about my grandma. When she was a kid, only some important people had telephones. Doctors, police, etc.

In her lifetime we went from that to today, and, since she’s still alive, even further into the future.

Whenever someone calls something impossible, I think about how far technology will progress in my own lifetime and I know that they’ve got no idea what they’re talking about. (Unless, like you said, it’s against the laws of physics. But sometimes even then I’m not so sure, cause it’s not like we understand those entirely. )
