At its Annual Business Meeting on 20 October 2010, the
IFAB discussed the implications of measurement systems that
are capable of automatically detecting the scoring of a goal
during a football match (so-called goal-line technology or
GLT). Consequently, the IFAB laid down a set of four basic
requirements a GLT system has to fulfi l:
-The goal-line technology applies solely to the goal line and
only to determine whether a goal has been scored or not;
• The GLT system must be accurate;
• The indication of whether a goal has been scored must
be immediate and automatically confi rmed within one
second; and
• The indication of whether a goal has been scored will be
communicated only to the match offi cials (via the referee’s
watch, by vibration and visual signal).
