I have a car stereo that streams audio and Pandora through Bluetooth. I'm thinking since I only use it in the truck I'd like to have a tag that auto turns on both Bluetooth and Pandora. I don't need it, but just toying with.
I have tags for Windows ( Nokia) and I used them mostly to change profiles according to whether I was at the office, at home or in the car. There's a app for that. I'm not sure if Android has provided for anything that elaborate yet. Windows also has apps that allow you to buy tags (NFC receivers) that allow you to tag and identify anything you purposely tag. Again, what does Android have available? Nokia was far ahead of the pack with NFC Tags. Even their wireless (desktop, car, pillows) chargers are tag points themselves allowing your Lumia to do specific actions when you touch the tags...
As for iOS (just for the information Jay. I know you don't like App(l)etizers) NFC is a no-no. Useless.
Regarding Android I guess you'll be the guinea-pig for the rest of the stackers.
Just an example.
They're little stickers that can be programmed to activate features or whatever when you to them with an NFC enabled phone.
I'm thinking of having one in my truck that turns on Bluetooth and opens my music player so my stereo can connect and stream my music. Really just convenience and some geekiness. I have cubbyhole that I sit my phone in (and will have a qi charger in it eventually). All I'd have to do is slide my phone into it and it would do what I needed.
