Abstract: At the shipping department of a company, contracted outlets or outlets of delivery companies, information concerning the shipper and receiver are written into a label having a memory, but no controller or energy source. The label has a transmitter and the label makes use of power supplied by RF query signals to fetch the information stored and transmits such information to a label reader located either in a portable recorder or at sorting locations. After the information is written into the label, the label is attached to the package. Upon being picked up, the label on the package is read by a portable recorder which transmits the information to a main computer.
