Abstract
A data processing system is described. The system includes a smart card having at least two independent electronic modules. A way to connect the multiple electronic modules through the use of the reader is also disclosed. By using circuitry in the reader to perform the interconnection function, the overall complexity of the electronic functions on the card can be increased without increasing either the size of the individual integrated circuits or the difficulty of fitting them into a smart card.
