If only your employees already carried around hand held computers that they could use to clock and in out for their breaks.
Apparently those were personal phones.
Then maybe having a way for them to flag at least a break/lunch in the system later when they get a chance to make sure compliance with legal and stuff is met if they need to.
Usually, unless you're a manager you're not allowed to carry a device onto the floor.
