Here's an article i've found on CNET on the uses of NFC :

At home
Put an NFC tag near your door and set it to do things like: enable Wi-Fi, decrease brightness, disable Bluetooth, and auto-sync. Using NFC Task Launcher, you can program the tag to "switch," so that when you exit your house and tap the tag for the second time, it changes those settings (like disabling Wi-Fi.)
Driving in the car
Stick an NFC tag somewhere near your dashboard or middle console and have it disable Wi-Fi, increase volume, and enable Bluetooth (for a headset). If you have your phone hooked up to the car's speakers, program the tag to fire up an app like Pandora.
Getting to work
Place the NFC tag on a phone dock or your desk's surface and program it to decrease brightness, disable sounds, enable Wi-Fi, and enable auto-sync. Depending on your habits, you might also have it launch a music app, open your daily to-do list, and even check you into Foursquare.
If you use the Switch option, you can tap the tag again on your way out and have it disable the previously enabled features. And, if you're an extra attentive husband or wife, the tag can also be programmed to send your loved one a text message alerting them that you've left the office and are on the way home.
On the bedside table
If you have a phone dock by your bed (or want to DIY your own), place a tag near the dock and program it to disable sounds, enable any alarms, disable auto-sync, disable the notification LED, and decrease the brightness.
Working out
The fitness types might benefit from an NFC tag on their workout armband or gym bag. For zero distractions, program the tag to enable airplane mode. Or, use the tag to fire up your favorite fitness app and playlist or streaming music app.
Little-known uses and unique ideas
Give access to your Wi-Fi network
If you'd like to give guests at home (or at an office) access to your Wi-Fi network without giving up your password, check out InstaWifi. The free Android app lets you program an NFC tag that, when tapped with an NFC-enabled device, gives the phone or tablet instant access to the associated Wi-Fi network.
Auto-start timers
How many times have you loaded the washing machine, walked away, and completely forgot you were doing your laundry? Put an NFC tag next to your washing machine and dryer that, when tapped, fires up a timer.
Get shortcuts to specific Evernote notes
With Touchanote, a free app that won the Evernote Developers Competition, tags can be programmed to link directly to specific notes. Their examples include a tag on your desk that opens a to-do list, or placing a tag near a product that links to a note with instructions on how to use it. For more examples and the full walkthrough, check out the video on YouTube.
Quickly pair with a Bluetooth keyboard
I asked for your ideas on Twitter and user @litcritter suggested sticking an NFC tag on the back of a portable Bluetooth keyboard. Tap once to enable Bluetooth, and tap again to disable it when you're done typing. Neat idea!
NFC keychain
Stick an NFC tag on an existing keychain, or order a customized NFC keychain online, and program it to complete a task you often do on the go. This can be anything from putting your phone in hot-spot mode to firing up your favorite playlist.
Prank your friends
The least practical, but arguably the most entertaining application of NFC tags is for pranks and rickrolling. If an NFC tag that contains a link is scanned, the Android device will not ask for permission before launching the browser. Scary, right? Questions regarding security come to mind, but can you imagine the possibilities? Fellow CNETer Jeff Sparkman suggests, "Program an NFC tag to open YouTube and play the video for "Never Gonna Give You Up." Hide tag near your target. Hilarity ensues!"
