At present several android phones have NFC built in. I used it when I had the Samsung Galaxy S3 with tags. These little tags were programmed to do certain actions. So when I got in the car, one swipe over the tag meant my S3 had been switched into Car Mode, Bluetooth on and volume at full blast. When I got home, I swiped the NFC tag by the hall table. Wifi was switched on, vibrate and silent turned on, Bluetooth turned off and my news feeds started fetching the news.

NFC can also be used to pay for services. But now there are plans a foot to use NFC as your car and house keys. One swipe over the lock and your car is unlocked and the same for your front door.

Now this all sounds good but what about the security implications. 10 years ago if you lost or had your phone stolen, it was a pain but that was about it. Nowadays if you have your phone stolen, it is more likely to be a smartphone worth £300-£700. So first up you have the actual cost of replacement. Then there is all the sensitive data and data apps hold on your device. Would you then feel happy if your phone was also the keys to your property and car?

Sadly, the way technology is moving forward this is more than likely to happen.
