How to use QR Code to open AppStore or deep link an app?

I'm currently developing an app that uses QR code to identify products. Here are the use cases:

1. If user hasn't installed the app, scanning the QR code should take them to AppStore / PlayStore to download the app.
2. If the app is installed, the user can use the app's scanner. In this case it'll extract the info (JSON format) from the QR code.

I'm not sure if QR code can achieve this. I know the first requirement needs a link to the AppStore. The 2nd requirement is just plain old JSON data. I don't know how to combine them into one QR code. Is this possible?

Thanks!
