SUMMARY OF THE INVENTION
2nd paragraph
In a specific embodiment, the non-ISO mode can be one that is associated with standard communication protocols that are used in personal computers, such as PS/2, USB and the like. An interface device which communicates with a multi-protocol smart card can be connected to any bus of the computer which operates in accordance with the desired non-ISO protocol. In the case of PS/2, for example, the interface device can be connected between the keyboard and the CPU of the computer system. Whenever a smart card is inserted into such an interface device, it communicates with both the CPU and the keyboard in accordance with the PS/2 protocol.
