A system for photographic film processing adapted to access stored information that is related to film processing. An electrically programmable read/write memory contained in a transponder is integrally attached to the film container used at each stage in the film processing chain. The transponder is capable of receiving a first RF frequency electromagnetic field and deriving power and address information from the first frequency, then generating a second RF frequency electromagnetic field in response, where the second electromagnetic field is characteristic of the data stored in memory. A transceiver is disposed within the processing apparatus, connected with an antenna and support components for polling each transponder. As instructed by a control logic processor, the transceiver communicates with the transponder to both read stored data from the transponder, such as manufacturing data for the film, and store usage and processing data to the transponder for storage in memory.
