You can use CrewPro's scanning feature at delivery. On the Overview page of the task, go to Packing List, you will see a Scan button. Tap on the button and point it to the code that needs to be scanned.
Once scanned, the app will display options such as Mark as delivered, missing, or damaged.
In order to scan an item at delivery, the item should have also been scanned at pickup. Only then will the code be stored within our system to be recognized at a at delivery.
