The barcode scanner for use with a parcel delivery system is an interface device. The barcode scanner for use with a parcel delivery system is configured for use in delivering packages. The barcode scanner for use with a parcel delivery system forms a wireless communication link with an appropriate authority. The barcode scanner for use with a parcel delivery system reads a bar code that appears on a package. The barcode scanner for use with a parcel delivery system transmits the read bar code and the location of the package to the appropriate authority. The appropriate authority logs the delivery of the package with the bar code. The appropriate authority transmits to the barcode scanner for use with a parcel delivery system the operational details about the next assigned delivery location.
