For some reason I started using my Nexus S again and I decided it was time to make use of the NFC capabilities of the phone.
I then went and bought some NFC tags from two sites that I heard were good:
Tagstand has a good variety of classic NFC tags, like the ones you can attach to a surface. In buynfctags you can get a variety of elements that has nfc capabilities like key chains, pens, etc. Some of the fun things of the NFC tags is that you can use an app called NFC TASK LAUNCHER to bind your tasks to different actions or toggle on/off some settings.
I ordered 15 nfc tags from tagstand and five nfc key-chains and today I received my 15 nfc tags but I have not had time to use them yet. I was also thinking which kind of applications could I make to make use of the NFC in my house or at work. I will post an update when I receive my last 5 key-chains and I will describe whatever I come up with.
