Presence, proved by a scan
Every zone and every session room carries its own code, and it changes every few seconds. Scanning it marks that person present. Photographing it achieves nothing.
- Codes rotate, so a photo is useless
- Every zone and room has its own
- Only ever matches someone who registered
The badge lives on the phone
Name, company, and a band saying visitor, exhibitor or crew. It is stored on the device rather than fetched, so it is there when the signal is not.
- Name, company and a role band
- There even with no signal
- Swap details by scanning each other
Who actually showed up
Afterwards you can see how many registered visitors arrived, split into those who signed up before the day and those who signed up on site.
- Registered against actually arrived
- Split into before the day and on site
- Exports with the time each one arrived
