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.
