Title: PCI-PCMCIA smart card reader

Abstract: A method and apparatus is disclosed for implementing an integrated video card and smart card reader. A single processor is used to perform both video and smart card reader functions. The processor simulates a PCI-to-PCMCIA detection logic scheme. An operating system, such as Windows, detects both a video card and a PCI-to-PCMCIA bridge. A smart card reader is attached to the integrated video card and smart card reader. Exmp. Claim 1 Ex Claim text An integrated expansion card occupying a single bus slot of a computer system, comprising: a first embedded device and a second embedded device wherein said first and second embedded devices are operable to share said single bus slot, said second embedded device comprising a bus host controller operable to input and output commands and data to said bus and to an expansion card device connected to said bus host controller; said second embedded device being capable of responding to registers that are queried by an operating system for a PCI-to-PCMCIA bridge so that said operating system detects the presence of a PCI-to-PCMCIA bridge.
