I am trying to follow this, but it is rather elusive.say, a building has an entry door and a security guard.
the person comes up to the building, swipes their card.
the security guard leaves their desk goes outside an then authorizes entry by swiping their authorization card on the same reader.Is there some way that the security guard could authorize this without exiting the building ?
What has any of that to do with what the OP is asking? He's talking about multiple people being able to swipe into the same computer from the same place. There's no reason that they can't use the same card reader.
