We are now operating with the Check In Qld App for COVID19 tracing. To be able to sign in with your smartphone or device you will need to download the Check In Qld App from Google Play or Apple App Store.
Get it on Google Play    Download on the App Store

This will save a lot of time compared to the Manual sigh in system. If you do not have a capable device you can get someone else to sign you in. If you haven't downloaded the App you can still check in on your phone by using the special numerical code below the bar code.
