So, a passphrase such as I Work in R00m 23a. isn’t a particularly good passphrase—it would be too easy to guess. Simply telling the user to rely on passphrases isn’t going to work. In fact, users will still use passwords such as secret and master because they’ve used them for so long.

You can use the key card to control access to the PC as a whole, or to control access to a specific application. When used for a specific application, the developer needs to provide code to read the card, determine its validity, and authenticate its user.
