How do TPMs compare with SmartCards or Biometrics?
They are complementary to the TPM, which is considered a fixed token that can be used to enhance user authentication, data, communications, and/or platform security. A SmartCard is a portable token traditionally used to provide more secure authentication for a specific user across multiple systems, while biometrics are providing that functionality in an increasing number of systems. Both technologies have a role in the design of more secure computing environments.
