The TouchChip Fingerprint Coprocessor is a hardware component used for biometric authentication, specifically for fingerprint recognition. It's commonly found in laptops, desktops, and other devices that offer fingerprint scanning as a security feature. The TouchChip Fingerprint Coprocessor enables users to log into their system, authenticate transactions, or secure files and applications using their fingerprints, providing a higher level of security compared to traditional passwords.

To use the fingerprint reader, you need the proper Windows driver installed. This driver allows the operating system to communicate with the fingerprint sensor and use it for various authentication tasks.
