Here is an idea on how to make sure the receiver doesn&#x27;t deny receiving the item. 
1. Add a barcode to the packaged item
2. The receiver has to scan the barcode using your mobile app before the traveler hands over the package. Your app will then display a passcode that the traver recognizes.<p>This ensures that you are certain that the receiver is who they claim to be and also that they received the item.
