Just returned

I see you’ve had no reply, so I’ll pitch in best I can. I’m in a remote province, ours runs within WeChat, under “official accounts” in the search bar. Mine only works if I’m on mobile data, and knows exactly where I’ve been. However I must login and enter/register  my temperature once a day before the timer expires and self certify my condition, or it will not generate a new green pass. Currently locked out as I missed one two days ago.

I am aware that less discerning security may accept a recent screen shot of your recent green code flashed at them.

Just for planning purposes, by the by a friend came in on a domestic flight this evening and was delayed for more than 2 hours while testing & registration was taken, despite having a good green code.

No worries. It doesn't sense your position at all.
Most places wouldn't check it nowadays.
And if you pop into some shopping malls or resteraunts who ask you to scan the QRs, they works the same way as in UK.  It just registers you, so the government can contact you if there was a Covid break out at the site.    I have experienced the strictest check in hotels, who check both the Beijing health kit and your journey track on another QR via mobile operators, upon your consent. I reckon the purpose is to check whether you have been to medium or high risk cities such as Qingdao recently and it makes sense.

Thanks for the reply.  Seems crazy that these apps are all separate instead of country wide.  I got mine to work.  Cannot see that it needs any temperature input or input of any kind. 
Was happy to see that it was still green this morning. Seems they all track you.  A friend had been in Qingdao before the virus started up again there. He left with his still showing green. Next day Qingdao announces it’s a problem. He’s now in a clean city but his indicator turned yellow because he’d been told n Qingdao the day before to notify him to self isolate.
Not thrilled about Big Brother’s tracking everywhere I have been.
Again thanks for replying.
Cheers,

I’m not sure it’s not tracking my position.  I started using the Beijing health kit.  I did not enter my location but it does show me that I’m in Shanghai now. 
I’m told that they will look before I board my flight today.

I notice in Shanghai a few places I went they did temperature checks. Pointless really considering that more and more people who are asymptomatic are testing positive

Thanks for the reply
