I have 10 QR codes which point to a common webpage www.demoexp.com/index.html. How does this site knows that it is accessed from which of those 10 QR codes. My index.html needs to know the QR code from which request is originating.

Are you generating these QR codes yourself? If so, you can add an id to the url as parameter, i.e. www.demoexp.com/index.html?id=1. So all 10 will still point to same url but now you will know which QR code led you there because of each having own id. – PiNaKa30 Dec 03 '19 at 05:08

Yeah so instead of just putting your url in the textbox of this site, put url + some parameter as i described above. it will still lead to your site but with QR code's id appended. Example: www.demoexp.com/index.html?id=1 for 1st QR code, www.demoexp.com/index.html?id=2 for 2nd QR code and so on... – PiNaKa30 Dec 03 '19 at 06:23
