Smart Card Blog - Multiple Profiles Coming!

What might be next - an upcoming change in Smart Card technology and/or configuration:

At present, Smart Cards do not support the storage and concurrent use of multiple PKI profiles. Because today's Cards lack the ability to store multiple profiles on a card, and because only one card/token is typically supported per client, customers will need to physically swap cards to use different signing profiles. I believe that the inconvenience of this will force a change (and in the near future), and am interested in discussing the implications of this.
