If you bend it a bit while pushing in the middle of one side the circular cover on the other side will pop off. You can see which side will pop off if you examine the tag carefully. Inside you will see a coil of copper wire and a chip glued to the other part of the tag. Good luck!
I was told elsewhere that the phone aerial would affect the tag and also the phones charging coil for wireless charging, think I will see if anyone has done it before.
