Keyfob for Android Bands NFC Sticker

I have started to use NFC tags to make my Android phone change profiles depending on the situation I am in (at home, work, in the car, on the bike etc). I can change ring tones, switch wfif/bluetooth on/off or activate apps among other things.

While the stickers are great I didn't really want to stick one to my motorbike or car. So I made this simple little keyfob 'adaptor' so that I can attach them to the keys of said transport.
