NFC Key Chain (Mifare Ultralight C)

Description

NFC Key Chains make a great addition to your key ring. You can program all kinds of functionality to these, but our favorite is setting up this key fob to automatically toggle WiFi and Bluetooth and Launch your favorite music application. By toggling WiFi and Bluetooth, you are Disabling WiFi (which was most likely enabled for your house) and Enabling Bluetooth (so your phone will connect to your car's Bluetooth audio player). Music will automatically start playing as soon as your phone syncs up with the car's audio player. These make a great gift for anyone with an NFC enabled phone (Nexus 4, Galaxy SIII, Galaxy Nexus, HTC Amaze and Nexus S, to name a few). To write to the tag, simply install an NFC application (For Android devices, we recommend NFC TagWriter by NXP).
