Redirected from: Microsoft CardSpace

Definition: Windows CardSpace


An earlier identity management system from Microsoft that never caught on. Built into Windows Vista and 7 and available for XP, Microsoft coined the term "identity metasystem" for an Internet identity architecture and designed CardSpace as its Windows implementation. CardSpace was a "card selector," which was the metasystem software that resided in the user's computer. See Microsoft Passport and identity metasystem.
