Ac the troll, or whoever you are, you should be the one to get out more, you obviously take all that is fed to you by the media, are you a sun reader? for your information that chip that has been drilled into the concrete step as described by cockneyguy or whoever .
I also have one but installed in my wall this was done by a sky engineer and I was told it was a radio frequency identification chip (RDIF CHIP) look it up you might learn something instead of making fun of people, DER.... I guess you have never heard of this chip have you, well do your research and then you might have something more constructive to say. needless to say I removed it myself when the engineer had left and the sky channels are still working fine, last time I had the chip it was whizzing across a local river.
