I think I remember hearing about that awhile ago.
Although we obviously have the technology for the "mark of the beast", I dont believe any of the news stories are the beginning of it. I believe that the mark (1) will be on a global scale where everyone in the world will be ordered to accept this "mark", (2) will happen during the "tribulation" 7 year period which I am sure we are not in right now.
But this just helps prove that the things in the bible are true. 50 years ago people were saying that it would be easy to copy a physical mark on your hand or head so you can buy food but with what we know today, it would be hard to copy a chip embeded under your skin that carries all your financial and personal information.
