COOL! WOO! My Idea for Rfid in mixed martial arts! WOO!

I was watching the karate kid over the weekend and I had a great idea for mixed martial arts fighting competitions. I thought that perhaps RFID could be used to help score the organized battles. The arena could have a magnetic field in it that could gauge where on the body contact was made and points could be rewarded accordingly. Also rfid could be implanted in what the fighters were wearing and could let the refs know when a score was made. this could get the ref out of the ring where they could be a distraction to the fighters or even worse get themselves injured. This could also help populize the sport and bring technology out of the workout room and into the ring.
