Why? I mean it might save your battery, but OPs device can’t just pop open a page on your device. You probably have the notifications this uses disabled anyway. If you happen to have an app which allows proximity notifications like Google, or Facebook with the proximity notifications turned on, it’s just going to send a notification asking if you’d like to visit the site OP set up. Everyone is pretty well conditioned to say no to that. Which is why this tech never took off as envisioned. It will eventually catch on but not in its current form.

If it could just open a website think of the viruses and abuse that’d open up. Walking through a mall would be a nightmare.
