Abstract
A method of connecting an IC card to a motherboard involves first connecting the ground busses, then the power busses and finally the general signal busses. When the power busses are connected, a low current is allowed to flow initially, then, a predetermined period of time is allowed to elapse for equalization of IC card and motherboard voltages, then a full current is allowed to flow. A method of disconnecting an IC card from a motherboard involves first disconnecting the general signal busses, then the power busses and finally the ground busses.
