How do they know this? [Distance run during World Cup game]

Watching the World Cup finals, we noticed that when a player came off the field, there was a caption listing how far they had run…to two decimal points.

This, of course, set off a lively round of speculation, with one side proposing GPS-enabled shoes and another side backing some sort of optical tracking. Anyone have any solid info on this?
