CrewPro comes packed (pun intended) with a scan feature. 

Scanning without an item selected

While in the packing list page of CrewPro, you will see the Scan button on the bottom left corner. When tapped for the first time, you will see a system request, the app is asking for permission to use your camera. You must grant this request to move forward. The app will start using your camera, point to your bar code or QR code. Upon scanning, you will see a details page for this package, here you can state what box and content you're assigning to this package.

Scanning with an item selected

You can also select an item from your list of surveyed items, tap on Pack in box or Pack item, you will also see the scan button here.

In both cases, once the item is packed, this code is also saved in the database. If a delivery task is assigned for this move using, the code will be sent to the device. The delivery crew can scan the code and they'll know instantly what's inside the package and its conditions.
