There are two possible reasons why the pre-registration QR code is not recognised by the display:
1. The visit date does not match the current date
The QR code sent to a visitor is only valid on the day(s) configured for the visit. For example, if a visitor arrives one day earlier than scheduled and tries to scan their QR code, an error will occur because the code is not yet valid.
2. The ‘I have a QR code’ checkbox is not enabled in the Visitor Display Profile
To allow visitors to scan their pre-registration QR codes, the I have a QR code checkbox must be enabled in the Visitor Display Profile.
