Goal-line technology is set to get the go-ahead when the International Football Association Board (IFAB) vote on Thursday over whether to use it.
The results of testing will be heard before IFAB are expected to approve the Hawk-Eye and the GoalRef systems.
How does Hawk-Eye work?
Hawk-Eye's system works by utilising six cameras per goal to track the ball on the pitch.
The system's software then uses "triangulation" to pinpoint the exact location of the football.
If the ball crosses the goal-line then an encrypted radio signal is sent to the referee's wristwatch to indicate a goal has been scored.
In line with Fifa's requirements, the whole process takes less than a second to complete.
The Premier League and Football Association can then introduce the technology into their competitions.
FA chairman David Bernstein and general secretary Alex Horne have travelled to Zurich to take part in the vote.
The English FA and their Scotland, Wales and Northern Ireland counterparts each has a single vote, while Fifa - world football's governing body - has four.
Any law change needs at least six of the eight votes.
How does GoalRef work?
GoalRef uses a microchip implanted in the ball and the use of low magnetic waves around the goal.
The system then detects any change in the magnetic field on or behind the goal-line to determine if a goal has been scored.
The process takes under one second with a message relayed to the referee.
