Why not put a QR code on your web pages that link to the page they are on? If you are on a desktop computer you could email yourself the link and pick it up on your mobile device, but if it's not your computer you're not going to have access to your email. Sure, you can take a chance and login to your email's web interface (if there is one). I am to paranoid to do that on a public computer (library, computer lab, etc.). I'm not taking a chance that there's malware on that computer swiping up passwords.
With a page QR code you could easily scan the code and have what you need. No more trying to figure out how to get to the page within a site, you go right to it. It's also great for scanning mobile-to-mobile.
At least put a QR code in the footer for your home page. I am surprised mobile app sites don't offer QR codes on the page or have QR codes that let you directly download the app.
