Hello i would like to know how to reverse engineer QR codes. the reason is the ridicilous QR check you got to do for about anything. any one there own on the faccinations. i just hate the privacy violation it comes with.
Now back to the point. the QR code stores all data localy in it. the QR code is the larges kind. no internet is needed for these checks to work so all data must be stored inside the QR code.
You can download the app to check the QR codes. now how can one generate a QR code that would work with such a app? how do you know what to put in this QR code?
If any one has a ideaplease let me know.
