How can a QR code on a wedding invitation be made reliable and safe for guests?

Direct answer
Test the QR code's real destination and provide the same essential details in readable text or another non-QR route.
Use a destination the hosts control or trust, check it on several phones and avoid links requiring unnecessary logins or sensitive data. Confirm that the printed size still scans and that the link will remain available. Guests should check the displayed address before opening an unexpected page. A working QR code is a convenience, not a reason to omit the venue, date or a contact from the invitation.
