At this point, most of you are likely familiar with NFC, what it does, and all the neat things you can do with it. And when you start writing your own commands to NFC tags, the possibilities are nearly endless. You could, for example, have a tag that silences your phone, disables GPS, and sets the screen brightness to 'auto' at night. Or have one for the car that enables Bluetooth and GPS, disables Wi-Fi, and then launches your favorite media player or navigation. And that's just the tip of the iceberg.

This contest is now over.

The final results are listed below. If you've won, you will be contacted in the near future. Congratulations!

As useful as it is, though, I've noticed one thing during my time with NFC: I sometimes get tags mixed up with each other. Because they all look the same, it's hard (if not impossible) to remember which ones do what. Our friends at Tags for Droid have a simple, yet effective solution to that quandary, though: stickers. Andy-approved (and adorned) stickers that let you customize each tag with something that represents its function. Brilliant.

Because NFC is so useful, we've partnered up with Tags for Droid once again to get more tags in to your hands. We have ten packs of the following to give away:

  • 5 re-writable NFC tags
  • 1 re-writable NFC keychain
  • 1 page of stickers to customize the tags appropriately

There are two different types of tags: Mifare and NTAG203. To keep the difference simple, here's the gist: if you have a Nexus 4 or Nexus 10, get NTAG203. For all other devices, Mifare works perfectly. Both types are available for this giveaway – if you win, it's up to you which one to get.

So, how do you enter? Follow the directions in the widget, of course:
