Reception books Demo Visitor from Demo Store onto Visitor pass 3, valid until 6pm, host: Finance Head.
The visitor taps the pass at the reception phone. The Echo at the desk says: "Demo Visitor from Demo Store is here to see the Finance Head."
They did not hear it and tap again. Inside the 90-second settling window, the welcome is repeated. They are not signed out.
Staff tap their existing ID cards at the canteen phone on the way to lunch. Nothing is written to the cards; the ledger records each tap.
The visitor taps on the way out: "Demo Visitor has signed out." The register closes the visit.
Pass 3 expires. Tomorrow it is booked for somebody else from the console. Same plastic.
