I strongly disagree with your idea, in my opinion entering a chip in the body can disrupt the health of the body. you should look for ideas about better technology.
I strongly agree to this point, implanting any such chip may deteriorate health of any particular, that is not a good idea, any external device use for such activities will be more appreciable but ofcourse less secure but we may be wrong at this point as well, future medical science may be so advance that implanting chip may not affect the body and it works in a normal way, everything is possible.
