A computerized "
smart card" which has a read / write memory and formatted data storage blocks is used to track the
life history of one or more associated
machine(s) (e.g., vehicles, medical
instrumentation and apparatus, business and
copying machines, etc.). The
smart card can store a variety of information including
machine identification, hardware /
software specifications, debit / credit, regulated performance, warranty / insurance, maintenance / service and operational transactions that might
impact the hardware,
software or the intended operation or performance of the
machine. The
smart card will be equipped to interact with any of a plurality of autonomous reader / writer smart card units and computer-based reader / writer smart card units that may be equipped to interact with any of the plurality of computer databases through the utilization of land or
wireless communications links. Preferably, each smart card will be associated with one or more specific machines at the time of sale of the machines, and will be periodically updated at each transaction (e.g., repair, scheduled maintenance, transfer of title, etc.) using reader / writer units operated by service technicians, repair shops, insurance agents, or the like. The stored
life history can be used for valuation, maintenance scheduling, problem trouble shooting, and other applications.
