Abstract: Mechanical/electronic apparatus for receiving, maintaining and transmitting information and data, the apparatus including a host computer and at least two PCMCIA cards parallelly positioned in a PCMCIA card compartment and having a communication interface between the PCMCIA cards. The communication interface can bypass the standard PCMCIA bus which connects PCMCIA cards to a host computer and thus accelerate the transmission of information and data. The information and data exchange may be performed by coupling the cards through capacitive coupling, optical coupling and inductive coupling.
