Goal-line technology or the GLT, will finally make its debut in the FIFA CONFEDERATIONS CUP 2013, BRAZIL. FIFA confirmed in April '13 the appointment of GoalControl GmbH as the official GLT provider for the tournament.
WORKING
The GLT system uses a magnetic field to track a ball with a sensor suspended inside. Thin cables with electrical current running through them are buried in the penalty box and behind the goal line to make a grid. The sensor measures the magnetic grids and relays the data to a computer which determines if the ball has crossed the line or not. If the ball does cross the line a radio signal is sent to the referee’s watch within a second. Adidas designed a ball that could suspend and keep a sensor safe and intact even when the ball is struck with great force.

FIFA has successfully conducted tests on the GLT systems installed in the Maracanã Stadium, Castelão and Fonte Nova in Brazil with the swiss test institute EMPA
The
use of this technology will probably not allow the blunders like the
disallowed goal of Frank Lampard against Germany in FIFA World cup 2010
and increases the accuracy of referee's decision.
