GEMPLUS GAM326 MEMORY CARD CONTROL
This section defines the commands needed to control the Gemplus GAM326 card type. There

It is assumed that the user has access to the manufacturer’s specifications for this type of card.
This section will address the memory available on the card as a file. For compatibility of
