Hi there! You can have a QR code show your personal information via a vCard QR code. Alternatively, you can use a COVID form QR code for entries. You can find more information about these two types of QR codes and more here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VBoV5AQRalc.html
You need to take a small pause between Q and R when you speak. It sounds like you are saying "Cure Codes" it should sound like you're saying "Cue Are Codes" just thought I'd point that out so that you aren't misunderstood in the future
