ActivCard, code generating

Hello Everyone,

In our company we use the ActivCards for generating the access codes for logins. In Windows there is a utility, which can access the card and generate such a code, called ActivCard Gold. My question is if there is something similar, but open-source for Ubuntu? Or if it is somehow possible to create such a solution with a combination of some packages? Or for that matter if it is possible to export the token from the ActivCard somehow and generate the codes without the card, directly from Ubuntu using some program... I mean, the option doesn't matter as far as I don't need to buy the ActivCard Gold software for linux...

Cheers,
Rocky
