## Frequently Asked Questions

### Q: What should I do if the app says "Attendee is not permitted to this session"?

**A:** The attendee is not assigned to the current breakout session. Switch to the correct session or check if the attendee should be added to this session in the portal.

### Q: What does "Testing badge scanned" mean?

**A:** A test name badge QR code was scanned instead of an actual attendee QR code. Make sure the attendee is showing the correct check-in QR code from their confirmation email or registration.

### Q: What if I get an unknown error?

**A:** Try refreshing the app (pull down to sync). If the error persists, restart the app and re-scan the login QR code.

### Q: What should I do if the attendee badge type does not match the current printer?

**A:** Connect a printer that matches the Printer Type configured for the attendee's selected Badge Design. The Check-in App can connect to one printer at a time. For bulk printing, incompatible attendees are skipped while compatible attendees continue printing.
