A method is provided for authenticating an action between a control point
and a user. A token which performs authentication is presented to the
control point. The control point may be authenticated by using the token.
The token may include a communication portion that obtains information
regarding the control point and that communicates with a token issuer to
authenticate the control point based on the information. A user interface
portion may be coupled to the communication portion to indicate a result
of the authentication to a user.
