The Physical Web is an open standard so any device can broadcast a URL wirelessly, so any phone/tablet/watch nearby can see and rank those devices. When the user taps on one, they just go to that web page. It’s really that simple. It’s about thinking small, enabling micro-information (what is in my prescription bottle) or micro interaction (can I buy a candy bar).
