I am always puzzled by the fact that a lot of people pick NFC as an example of something seemingly useless.
Having used it on a daily basis for around two years now I find it very useful by having a handful (actually 4) NFC tags at different spots - all of them set as toggles that turn on one set of features at first 'bump' and then a second one on the next 'bump'. Here are some examples from the top of my head - there are actually more things going on with each of the tags than this:
Near my door: Switches off wi-fi, increases screen brightness, turns off the main lamp in my living room (I have a couple of WeMo-switches in my home, and the main lamp is always on when I am home). This is when leaving, the opposite happens when returning.
On my desk at work (below my desk pad - can't be seen): Switches to the work wi-fi, disables work-mail checking on the phone so I don't get lots of notifications for stuff that I already get on my computer, turns off sound.
On my night stand: Switches to silent mode and only gives audible notifications from a few selected contacts - and alarms of course. Turns off all WeMo-connected lights.
In my car: Switches different settings to car mode and hooks up bluetooth.
All in all very useful. Of course you could toggle all these settings manually each time, but how uncool is that
Just a quick run down of what NFC can be used for in daily life - things like payment that many think is the main use is just a fraction of what it actually can be used for.
So, how is this for daily use of the phone? NFC surely saves me from lots of switching stuff around during the day.
