Biometric mice add security to your computer system by permitting only authorized users to control the mouse and access the computer. Protection is accomplished with an integrated fingerprint reader either in the receiver or the mouse. This feature enhances security and adds convenience because you can use your fingerprint rather than passwords for a secure login.

To use the biometric feature, a software program that comes with the mouse registers fingerprints and stores information about corresponding authorized users. Some software programs also let you encrypt and decrypt files. For more information about biometric fingerprint technology, see How Fingerprint Scanners Work.
