That’s not any data at all. Just anecdotes.
We already have plenty of lockdown anecdotes and we all know how many people are adhering to lockdown laws. This is just QR code-like and not much else.
Again, it’s meritorious and I won’t have any problem using it, but it’s impractical in terms of achieving any meaningful impact.
About the only use for it I can see is for overseas travel where every single person can be checked, and it can be enforced securely, each and every time for each and every person.
What data do you want? There's proof the regulations are in place and being policed, establishments penalised.
Keep in mind MSM here is government owned.
