Enhanced testing of one of the two FIFA-selected goalline technologies took place in Nuremburg on Thursday.
After nine months of testing, a decision on goal-line technology is set to be made by the International Football Association Board within a matter of weeks.
The IFAB board consists of various representatives of Fifa and only two of eight initial companies have met IFAB criteria for the final phase of testing in Nuremburg.
Hawk-Eye's system uses optical recognition with cameras, whilst GoalRef utilises a magnetic field.
Fifa's Media Relations manager, Alex Stone, explains the next stage of the selection process.

"If the decision is a positive one on the fifth of July, then it is a 'green light.' Then it is for individual leagues and competitions to enter into a commercial agreement with the company.
The company then has to agree on the costs. They have to install the equipment in every stadium. Then FIFA and EMPA, they have to test the equipment and certify it to make sure it works. That will take time. We don't know how much time."
A final decision is to be made at the Board's Special Meeting in Zurich on July 5th.
