Can I make a qr code generator app that contains user information?

I want to create an app that makes QR code that contains user's information.

The current scenario is that after sns log into the app, make QR code that contains user's account information

After that, I would like to create a QR code generator app that allows the user's information to be sent along with the QR code when User scan to QR code scanner.

What I'm curious about right now is whether I can make a QR code that contains the account information for that user, and if I can, what modules I can use to create.
