Getting a normal user to get you a MAC address would be... challenging. Especially on devices that randomize them.
Most those places have an "app" I'm sure someone smart could figure that one out.
iPhones apps are not allowed access to your MAC. It would allow apps to individually track users.
iPhones at least randomly change MAC addresses as an anti tracking measure. Besides, when I travel with my wife. do I really want to have to give my MAC addresses to both of our laptops, both of our phones, and both of our iPads?
I don't want to preenter a single MAC, let alone the 7 that are coming along for the ride when I and/or my family travel
Hmm. How would this work for regular non-tech savvy users?
I doubt regular customers know what a MAC address is.
