How to store QR code data in Firebase after scanning

I'm curently working on an application that has register/login form of a user and a shop, whenever a user is loged in with it's credentials the User Profile is being displayed and a QR code with it's data is being created.

Whenever a shop is logged in it can scan the User's QR code and show it's credentials, I'm trying to figure out how can I store user's credentials when scanned to a new path created on the Firebase to show in which shop the user has entered.

I'm thinking that somehow whenever the shop is scanning the QR code of the user, it is going to store the data to some strings and then a new "field" will be created in Firebase.

Also the library that I'm using for the QR code is the Zxing library.
