To generate a QR code to use with our Lateral Flow Tests.

Are you able to make a QR code that will work with the app programme TAC Verif - it is for lateral flow testing for our company and we need to generate a QR code that will last for 3 days and then expire. I have some examples of those that are required. The programme link is: https://play.google.com/store/apps/details?id=com.ingroupe.verify.anticovid
