Abstract
A print having information associated with the print stored in a memory coupled to the print. A print, processed by an image processing apparatus, having an attached memory for storing detailed information about the print and allowing contactless access using an electromagnetic frequency signal. A transceiver, connected to a control logic device, communicates with a transponder that is attached to the print substrate and is integrally coupled to the memory. The transponder is capable of receiving a first electromagnetic field (frequency) from the transceiver and deriving power and address information from the first frequency, then generates a second electromagnetic field (frequency) in response, where the second electromagnetic field is characteristic of the data stored in memory.
