  • Publication number: 20040246104
    Abstract: To monitor goods and/or containers a method and a system are proposed that comprises the following components. Each good or container is allocated a transponder on which influence variables on the good or on the container are recorded by means of a sensor means. The transponders are wirelessly connected to each other, e.g. as an ad-hoc network. One of the transponders transmits all of the recorded influence variables to an allocated communication unit. In this way, a system is provided that automatically, and without manual intervention, provides very early detection of impermissible effects on the goods to be stored or transported. In this way, for example, a re-ordering can be activated before the impaired goods are delivered to the intended recipient.
