Our supervisor likes to follows us with a camera. As for tracking, basically the board records the information, which is downloaded later. They won't go to live updating anytime soon. The constant transmitting would put a big drain on the battery, and with no way to recharge it during the day, they'd have to pull work off us.
You can tell with the board is transmitting information, it's when you go you punch in info, or scan something and it has this long pause before responding.
