Client wants a button on the mobile web app that launches a QR code scan (with camera on iPad) then returns to the mobile web app with the QR code info. Wondering how best to achieve this and/or if it's even possible. Thanks!

Use the camera to read a QR code Open Camera, then position iPad so that the code appears on the screen. Tap the notification that appears on the screen to go to the relevant website or app.
The javascript library available at mebjas/html5-qrcode on Github allows users to add a QR code scanner in their web applications. It works cross-platform and across different devices like PC, Mac or smartphones.
You can create a QR (quick response) Code to share a page from Chrome with others. Go to the page you want to share. Find the address bar: Linux computers: On the right of the address bar, click Share.
Not really possible, sorry.
The closest you can get is some apps have a URL scheme (redlaser://, for example) that you could provide a link to. There's no way of detecting that they've got the app installed, though.
