I saw this on my breakfast cereal box (in the US) and looked it up. A company called Navilens made this to help visually impaired people with things like street signs, etc… neat!
EDIT TO ADD: Haha, I forgot I am on lemmy so we’re discussing the technology and licensing issues, instead of focusing on how this might improve the lives of visually impaired people.
In Madrid a lot of bus stops has these signs to help people to know when the bus will arrive by scanning it.
Makes sense, they are a Spanish company, they’re probably expanding locally first.
I don’t get the benefit compared to a normal QR code, though. Seems like linking a website with a sound file would work just as well.
