Hi, What seems more user-friendly to me is that a single USB key device needs to be sharable between 5 credit cards, rather than having 5 separate devices. What I still do not understand is how a Web site communicates with the USB key device.
Web site communicates to a web browser which in term communicates to a set of standard APIs known as PKCS#11. Every smart card token or USB token vendor who wants to sell their token will provide you with their PKCS#11. Being a standard, your browser will know which API to call within the PKCS#11. If the token is in the form smart card, then the PKCS#11 provided by the smart card vendor will include means to call the smart card drivers provided as well. If the token is in the form of USB, then the PKCS#11 provided by the USB vendor will inculdes means to call the USB drivers as well. Bottom line - whatever happens belows PKCS#1l should be transparent to the web browser (or any PKI enabled application). Regards Sam Koh
