Paper sign in sheets
A clipboard at the gatehouse is the only record of who walked on. It is transcribed hours later, if at all, and by the time anyone needs it during an incident the page is in a folder in a demountable.
Site access and gate control reads the same worker record as the office. Inductions, licences and site rules resolve at the point of entry, so the gate becomes a control rather than a queue.

A high risk licence lapses quietly and nobody finds out until the worker is standing at the gate, kit in hand, at the start of a swing that was planned around them.
Asked how many people are on the ground right now, the honest answer is a guess from the roster. Musters are counted by walking the line and hoping the roster was right.
A contractor inducted in March turns up in June and is inducted again, because the first record sits in another company system and nobody can find it in time.

Every person has a single record carrying their inductions, licences, medicals and site rules, whether they are direct, labour hire or a subcontractor.

Each site sets what it requires. The rules live with the site, not in a supervisor's head, so a change applies everywhere at once.

The gate resolves the record against the rules as the worker presents. Valid, expiring or blocked is a decision the gatehouse can act on immediately.

Anything about to lapse appears on the planner's list while there is still time to rebook, rather than at the gate on the morning of the shift.

Who is through, at which gate, on which crew, updated as it happens. Musters read from the same picture the office has.

Every decision at the gate is evidenced, so an audit or an incident review is a query rather than a search through folders.
Shared by the gate, the planner and whoever prepares pay.
Changed once and applied everywhere.
Licences and inductions flagged before travel, not at the gate.
Ready for a muster without a walk around.
Contractor inductions found and reused instead of repeated.
Every access decision kept as it happens.
Works alongside the tools you already use.
