Probably very easy to fake. I have read, that you need a QR code reader and writer software and a software to make your own public and private 56 bit key.
Since your key is not fake, you can encode the fake information and when produce a QR code. And Switzerland is releasing an app, where you can test your selfmade QR code. Isn't that handy?
Not easy to fake. They keep the private key they use to sign it themselves, and there is not just one key, any hospital or testing center has their own key.
