Re: I'm puzzled by these attempts.
There are other uses for phone NFCs?
The tags are what convinced me that NFC was useful. The one in my car turns on BT and GPS, turns off WiFi and pairs the phone with the radio. Likewise the tag just in the front door of the house reverses those settings while the one in the bedroom puts it in "bedside mode" and turns on the alarm. The tag in the office toggles the ringtone to a more workplace friendly tone and volume and turns off BT, GPS and WiFi to save battery. Sure, I could probably do the same thing using location based services but to me NFC seems to be a better solution.
