Yes you can. Take a look at this widget: https://appstore.home.mendix.com/link/app/109513/
There you will find the barcode scanner to read the QR codes.
Do follow the academy lessons and especially this one: https://gettingstarted.mendixcloud.com/link/module/231/lecture/1793

Hi Anthony Zaldana,
Short answer: Yes =)
There is a component in the app store to read QR code. You can generate QR Code too.
And this mechanics you described should be controlled by microflow logic and some screens.
Perfectly doable.
