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).
