"Goal-line technology will be tested at Wembley when England host Belgium in a friendly on 2 June.
Hawk-Eye, a camera-based system, will be used by independent testers during England's final game before Euro 2012. But the match officials will have no access to data and the trial will have no impact on any contentious goal-line decisions.
The first live test of Hawk-Eye's system was conducted earlier this month in the Hampshire Senior Cup final."
