German firm Cairos will be among the bidders to install systems for next year's World Cup in Brazil and the 2013-14 Premier League season.

　　The Cairos system is similar to the German-Danish GoalRef prototype already approved by FIFA. Both use a magnetic chip inside the ball which is activated when crossing the goal line.

　　The other licensed system is the Sony-owned Hawk Eye, used successfully in tennis and cricket, which comprises a series of strategically placed cameras around the stadium.

　　"We have met all of the requirements set out by FIFA for its goal-line technology which passed the test criteria, and was subsequently granted an official licence," Cairos said in a statement on Monday.

　　FIFA revealed last week it is seeking tenders to implement goal-line technology at June's Confederations Cup in Brazil and the World Cup a year later.
