hi, thanks for your review of the Joy! We're booked to be on the Jade in October and was wondering upon arriving for embarkation, if they scan everyone's QR code from their phone/print out of their covid vaccination proof? I have 3 different QR codes for the 3 vaccinations and am worried what if it doesn't scan properly? I don't have any way to check if they scan properly as nowhere else scans QR codes for vaccination proof anymore for a long time now. Or do they just look at the paper or at your phone which states the dates/type of shots you've had and that's all they care about, or do they check every QR code separately? I don't want to get denied boarding and sent home because of a technical glitch in the QR codes!
