football was contrasted with other sports, which had incorporated video replays and other systems into their rules. In response to this, FIFA decided to test a system by Adidas in which a football with an embedded microchip would send a signal to the referee if it crossed a sensor going through the goal. According to FIFA president Sepp Blatter, "We did different tests at the Under-17 World Cup in Peru but the evidence wasn't clear so we will carry out trials in junior competitions in 2007". However, those trials did not materialise and by 2008, Blatter had rejected the system outright, describing the technology as "only 95% accurate". FIFA and IFAB were resistant to introducing technology in the game, voting in March 2010 to permanently ditch the technology. Following several refereeing errors at the 2010 FIFA World Cup – including the disallowed goal in Germany's 4–1 victory over England, when Frank Lampard hit a shot from outside of the penalty box that bounced off the crossbar and over the line; the ball came back out and the goal was disallowed because the assistant referee did not call for a goal – Blatter announced that FIFA would reopen the goal-line technology discussion. Before Euro 2012, UEFA president Michel Platini dismissed the need for goal-line technology, instead arguing for placing additional assistant referees behind the goal. However, in a Group D match with Ukraine losing 1–0 to England, a shot by Ukraine's Marko Dević shot briefly crossed the line within clear view of the goal-line official before it was cleared by England's John Terry, reopening the debate, although an offside in the build-up to the incident was too unnoticed by the match officials. Initial testing Heeding calls for the use of technology, in July 2011 FIFA began a process of sanctioned tests that eventually resulted in the approval of the systems used in the current game. The first stage of testing considered multiple goal-line technology systems, with the requirement that the system notified the referee of the decision within one second of the incident happening. The message needed to be relayed via a visual signal and vibration. Tests were conducted by Empa between September and December 2011. Tested systems included: A system from Cairos Technologies, in collaboration with Adidas, based around a modified ball with an implanted chip and a magnetic field generated by thin cables behind the goal line.
