In two hours, Bough would use Chase's original card to open the door to the MIS office and retrieve the chip. The system would have logged him out of the computer by then, and then registered the door opening with that ID. FastJack had long ago noticed that the Renraku system had no way of discerning in which direction a person was moving through a door, only that someone had passed through. Tonight Chase's team would be using that to their advantage.
