I ordered a bag of some NFC tags to play around with allowing objects to tell more of a story. I placed one behind a wedding gift from close friends on our wedding day in Copenhagen. I programmed the NFC tag to invoke Google Street view and thru the device the user is able to see exactly what we saw, in the exact location where the photo was taken. It definitely added a new layer of depth to the photo and allowed others to share in our experience.
Here is a quick video of this NFC tag works with an NFC enabled smart phone (Google Nexus S)
