A portable item tracking unit includes a bar code reader for capturing a bar code related to an item, a microphone for capturing an audio identification from a recipient of an item, and a memory. The memory associatively electronically stores a digital signal related to the audio identification along with a digital representation of bar code data to provide audio proof of delivery of the item. A display and a speaker may respectively display the stored bar code related to the item and audibly broadcast the electronically stored audio identification for the item. A user input is preferably included for verifying that the input of the bar code and the audio identification is satisfactory. A transferring circuit transfers the electronically stored bar code and the electronically stored audio identification to a host computer. The host computer includes its own memory for associatively storing a plurality of digital identification indicia having a respective plurality of digital audio identifications for a corresponding plurality of items. A consumer can then access the host computer via a telephone network. After the host computer accepts selection of an item, a reconstruction circuit converts the digital identification indicia and the digital audio identification for the selected item into first and second audible messages. A transmitter may then transmit the first and second audible messages to provide audio proof of delivery of the item. |
