Abstract
Apparatus for communication of information from a passive identification module that may be associated with a fluid container and an active communication module associated with a fluid delivery device. The passive identification module has no independent battery or power source but receives its operational energy from an RF signal generated by the active communication module. Upon initiation of a fluid delivery transaction a communication link is established between the passive identification and active communication modules and will proceed only if appropriate authorization is received by the active communication module and an associated information storage and retrieval device. Information regarding the fuel delivery transaction may be stored on the storage and retrieval device and may be communicated to another local or remote device for further processing.
