Seems to be new Abbreviation to learn like CTS/CLS/CLR.
I am sure that you will face questions like what is WPF/WCF...etc? in your next interview. So be prepared.

So here is the interview Answers for them. But do go through some more details as you know some time answers like "CTS is Common Type System" will not work. Read in detail to avoid being a sandwich when grilled by interviewer.

What is Windows CardSpace (WCS, formerly “InfoCard”)?
Windows CardSpace enables users to provide their digital identities in a familiar, secure and easy way. In the physical world we use business cards, credit cards and membership cards. Online with CardSpace we use a variety of virtual cards to identify ourselves, each retrieving data from an identity provider. Don't struggle with usernames and passwords, just choose an information card!

I will be covering each of them in separate articles. So wait....for something usefull to come.
