Smart card overview

A smart card is a credit card sized device you can use for storing sign-in passwords, public and private keys, and other personal information. Smart cards provide tamper-resistant and portable security solutions for tasks such as securing e-mail and logging on to a domain.

Support for smart cards is a feature of the public key infrastructure (PKI) that Microsoft has integrated into Windows XP.

Smart cards provide:

Tamper-resistant storage for protecting private keys and other forms of personal information.

Isolation of security-critical computations involving authentication, digital signatures, and key exchange.

A way to take logon information and other private information with you for use on computers at work, home, or on the road.
