Have it ever happens to you that when you reach office, you got to switch your phone to silent, off the Wifi, or do some setting that you will minimize disruption to the colleagues around you. Then when you are back home, you got to do the reverse all over.
Bet there are those times that you forgot to set your phone to silent and it just ring loudly in the office and everyone is looking at you fumbling to answer that call. Or you forgotten to switch the phone back to ringing and gets missed call or messages late.
That is why I'm quite excited to see the Samsung TecTiles. Its basically a sticker and when you tap on it, it will just program your phone to whatever setting you programmed the sticker to be.
The only issue is that I can only find one for Samsung and Android. Other brands or iPhone users just got to keep searching.
This is one whole list of things you can program TecTiles to do for you when it's tap on.

Settings & Apps:
     
Change Phone Settings
      Make a tag to set your phone up the way you like it when you get 
to work, or when you get in your car. You can even set an alarm time for
 a bedside tag. You can set individual settings, or combine settings to 
optimize your phone for your location - at home, at work, in the car, or
 other places.
     
Switch Phone Profiles
      Switch between pre-defined or custom profiles. Profile TecTiles 
let the result of scanning be defined by the user. For example, create a
 “meeting” profile and put it on the conference room table that one user
 will have mute their phone while letting another user set their ringer 
to vibrate.
