QR Codes for Covid scanning

Morning all. I have my daughter panicking that I don’t have a QR code for parents to scan. Do I need to have one at my home. I’ve been away with no internet so I might have missed any notifications about this and I know you are all on top of all the info we are getting

As far as I know, we don't have to have one.

We have the track and trace contact details for anyone who may be here at any given point.

That’s what I thought. Thanks

I don't have it too
