Abstract
The present invention is directed to novel systems and methods for transmitting location event information to and/or from an electronic device, such as a radio frequency identification (RFID) tag, from and/or to one or more location ID stations. Among other things, a method is disclosed that involves wirelessly receiving at least one signal at an electronic device associated with a package as the package is transported from a source location to a destination location in a manufacturing process, supply chain, and/or distribution network, the at least one signal including location event information that is sufficient to specify a location of the package at a time the at least one signal is received. The method further involves, based upon the at least one signal, storing data representative of the location event information in memory of the electronic device so that the location of the package identified by the at least one signal can be subsequently ascertained by retrieving and analyzing the data.
