Make all players wear the same size boots….There’s two systems. This one and the one used at the World Cup have a chip in the ball (what has been referred to as the snickometer when it’s shown on screen).
The Premier League will use an AI method. Basically a camera tracker which can measure the balls inertia and position. Like Hawkeye.
Both are accurate to something like 2ms.
For me they should build that 2ms + some buffer into the margin of error they use when overturning decisions.
