Inspired by this site I decided to have one of my rfid tag embedded into my iphone 4s, as to use is a master key on my future developments.
I started dissolving the tag with acetone, and while dissolving I started to read some documents on RFID antennas (link) great document, covers from the basics!
Let me tell you a couple of things about embeding
1) I dissolved 2 tags.... first one, stopped working.
2) The one I dissolved does not fit, and cant tear it apart. So, I'm not so happy, though this was going to be easy.
