Abstract: A method and system for generating and processing object identifiers in an e-commerce environment. The system comprises a database for holding objects; at least one identification system for providing unique identifiers for objects, wherein the identification system obtains location and time information from a global positioning system (GPS) and encodes the location and time information into each unique identifier; and an application for processing the objects, wherein the application includes a system for processing the unique identifier.

Abstract: A system and method of synchronizing a pair of communication devices using a carrier signal from a global positioning system (GPS). The method comprises the steps of: receiving a GPS carrier signal at a first device; at the first device, deriving from the carrier signal a transmitter clock signal having a predetermined frequency; transmitting data at the predetermined frequency from the first device; receiving the data at a second device; receiving the GPS carrier signal at the second device; and at the second device, deriving from the carrier signal a receiver clock signal having the predetermined frequency.
