I asked my driver a few weeks about checking into the individual vehicle and he said their ‘system’ has a record of our pick up and drop off times that they can supply to the contact tracing team so a QR check in is not required. The information is recorded by car so if there was a concern about a particular driver or vehicle the information is readily available. My driver has been wearing a mask when required to do so. Masks haven’t been required for green flights all the time. They are at the moment though.
There is a reason for not having a separate system instead of the QR system.
If the QR code system is used universally, it speeds up the contact tracers job, and in contact tracing speed is of the essence.
This is especially so when daily numbers of new infections start to accelerate, as it gets increasingly hard time wise for contact tracers to get ahead of the outbreak to ring fence it.
