GOALREF Creates a low magnetic field Ball has a microchip that interferes magnetic field Notifies the ref in less than a second Pros: Cheaper Not dependent on visibility of the ball Cons: Emitters are set on posts, which can be a possibility to hurt players Increase of cost in balls Increase soccer ball weight No hard evidence to prove it’s correct Affected by external magnetic interference
