About Smart Cards and Fingerprint Readers
Smart cards are portable credit-card shaped devices with internal integrated circuits. The top surface of the smart card usually contains an embedded
processor under the gold contact pad. The combination of the small size and integrated circuits make smart cards valuable tools for security, data storage, and
special programs. Using smart cards can improve computer security by combining something a user has (the smart card) with something only the user should
know (a PIN) to provide more secure user-authentication than passwords alone.
The fingerprint reader is a device that you can use to help keep your Dell™ computer secure. The reader is a strip sensor located on a peripheral device for
your computer. When you slide your finger over the reader, it uses your unique fingerprint to authenticate your user identity.

NOTICE:
Although passwords provide security for the data on your computer, they are not foolproof. If your data requires more security, it is your
responsibility to obtain and use additional forms of protection, such as data encryption programs.
NOTICE:
If you leave your computer running and unattended without having a system password assigned, or if you leave your computer unlocked so
that someone can disable the password by changing a jumper setting, anyone can access the data stored on your hard drive.
