Gate
Gate pass
Who entered, with what, and when they left.
A pass is a person or a vehicle, a reason, and a time in.
Out closes the pass. An open pass at the end of the shift is still on the list.
Material leaving the gate is a line on the pass. The store can match it later.
A visitor and a staff exit are different kinds of pass. The gate does not mix them.
The security desk sees today's open passes without a stack of slips.
A pre-approved visit is already on the list when the person arrives.
A refused entry is a note. It is not only a wave at the barrier.
The office can search one name and see the last visits.
A new guard can issue and close a pass on the first shift.
The handover between shifts is the list of passes still open.
