How does goal-line technology works in 6 key points

• Seven camera’s per goal detect if the ball has crossed the line or not.
• The referee will get a signal on his vibrating watch with the text GOAL just one second after the ball crossed the line.
• The system works perfectly even when there are many people standing on the line. Sportsmail’s Laurie Whitwell tried it: “I lifted the ball up and walked over the line with it tucked under my arm to see if that affected things. Again the machine on my wrist told me it was a goal.”
• Hawk-Eye can provide a TV replay to categorically prove the decision is correct, the company says.
• It is technically possible to also provide a “near miss” signal to the watches so the referee also receives a positive confirmation that the ball did not cross the line in a close incident.
• The system will not be disturbed by thousands of fans using their mobile phone. Mail Online wrote: “Instead, it is an automatic transmission from the cameras. Not wifi or Bluetooth, which can be affected when 70,000 people bring mobiles to grounds, but Hawk-Eye’s special method that they do not reveal as it is a secret to their success.”
