QR codes - do we have a recommended generator?

HI all
is there a recommended QR code generator? I’m assuming that as part of the development of the COvid Safe checkin system a review would have been done on the most suitable one.
I’d love to hear about it, to feed into our own brand and design guidelines

Hi Mel,
Paul from the nsw.gov.au program delivery team.
We developed the QR generator for the Covid Safe check-in however we did not adopt an off-the-shelf QR generator product.

The approach we took was to use the existing functionality within our Drupal core CMS and customised it for the business needs, this also helped with streamlining the Covid Safe business registration customer journey.

Happy to share our learnings and approach on how we delivered this product for the https://www.nsw.gov.au/ website.
