Show me everything on Security Token and Smart Card Technology

DEFINITION - A security token (sometimes called an authentication token) is a small hardware device that the owner carries to authorize access to a network service. The device may be in the form of a smart card or may be embedded in a commonly used object such as a key fob. Security tokens provide an extra level of assurance through a method known as two-factor authentication: the user has a personal identification number (PIN), which authorizes them as the owner of that particular device; the device then displays a number which uniquely identifies the user to the service, allowing them to log in. The identification number for each user is changed frequently, usually every five minutes or so.

Unlike a password, a security token is a physical object. A key fob, for example, is practical and easy to carry, and thus, easy for the user to protect. Even if the key fob falls into the wrong hands, however, it can't be used to gain access because the PIN (which only the rightful user knows) is also needed.
