Well, if the NHL actually added the damn chip to the pucks, people could see it(there exists a chip for hockey pucks that lets you overlay/enhance the image using position data from the chip, somewhat like the 1st down line in football).
Actually the company that did the 1st down line, was responsible for the whole hockey puck thing(you know, the hockey puck with a blue auroa around it). It didnt last a season, fans hated it. Maybe if the revised it, it could work but when they did it, it just didnt work.
