Parking desk
A bay, a vehicle, and the time it left.
An entry takes a bay or a ticket. The time in is the start of the stay.
Exit closes the stay and shows the charge, if you charge one.
A monthly pass is a vehicle the gate already knows. It does not take a visitor ticket.
The board shows bays free and bays held.
A vehicle still inside at the end of the day is still on the list.
Lost tickets and manual exits are notes. They are not invisible exceptions.
The cashier sees the shift total of tickets closed.
A new attendant can open and close a stay from the gate screen.
Two gates can share the same yard so a car is not inside twice.
The close of the shift is entries, exits, and vehicles still in.
