Tracking
Every bag has a label. Every handoff has a scan.
The driver app records the door. The desk log shows the same events. The trace below is a sample, not a login.
Desk log
No bag on the desk yet.
Labelled
Each bag gets a QR label before it leaves the site.
Scanned twice at least
Once at collection. Once when it is returned.
Tied to the driver app
The scan at the door is the same record the desk sees.
