in American football, Cairos Technologies' technology would have a similar function. In an interview with Reuters, the company's sales director, Mario Hanus, said the chip could be especially useful for those times when a referee must determine if a ball crossed the first-down marker or goal line. If the ball does, in fact, pass the first-down or goal line, an alert would be sent from the microchip to the referee's watch. The idea is to take the element of human error out of the equation.
