NFL in discussions about using chip-in-ball technology
"There are other sports more open to the topic maybe than soccer at this time but the requirements are different and the development was in first placed to solve that particular issue (in soccer)," Hanus said.
However, he said that the technology could easily be adapted to rule on debatable first down decisions, especially when a scrum of players block the view of the officials.
"In American Football you have the same situation, you need to cross a line and the ball needs to be over the line 100 percent and they (the players) are always above the ball (covering it)."
Hanus demonstrated the technology which uses a soccer ball, made by German sporting goods company Adidas, capable of holding a small chip in the center and, should it fully cross the goalline, would send an alert to an officials' watch.
Cairos say their system, which they have been working on for nearly a decade, is not as expensive as many forecast and would prove cheaper than soccer employing two additional referees in matches, as they will use for some European games this season.
