I've found a very handy use for NFC tags. When I'm in my car I like to steam music from my phone to the car's stereo system using Bluetooth. Also it is handy to enable the Samsung "Driving mode" so I get a bit more information read out to me, e.g. if the phones beeps and it is a text message the phone will tell me who the message is from so I can decide whether I should park up and read it. Ideally I don't want WiFi on to cut power consumption. When I get out of the car I want to switch off Bluetooth (to save power), switch off Driving Mode and switch on Wifi. This all involves changing several settings on the phone everytime I get in and out of my car. Fortunately NFC tags can make this much easier.
