They are used as a security system.
E.g.
Someone who worked in an office would touch the fingerprint scanner and be recognized as a worker and get in fine. Someone who shouldn't be going into the office would set off alarms when their fingerprints get scanned.
There are a wide variety of fingerprint scanners available for your laptop. There are high quality fingerprint scanners to look at and compare at www.staples.com.
The term used to describe fingerprint scanners is "biometric scanner." These devices analyze the unique patterns and ridges of an individual's fingerprints to verify their identity. Biometric scanners are commonly used for security purposes, such as unlocking devices or accessing secure locations.
Similar to a password, laptop fingerprint scanners are programmed with your information and will require your fingerprint in order to unlock. This security system is not foolproof but is much more secure than a regular password.
A biometric scanner is a digital scanner used for imaging biological details. The phrase biometric scanner refers to the various fingerprint readers, palm scanners, retina scanners, and voice scanners used to verify identification.
Iris scanners and fingerprint scanners are alternative (biometric) input devices for computers.
there are many laptops with fingerprint scanners are available in the market.UPEK Eikon TCRD4 USB Fingerprint Reader - 1 x USB - Finger Print Reader is the example of such kind of laptop.HP Business Elitebook 8560P 15.6" Notebook is another example of such kind of laptops.
Common instruments used in biometrics include fingerprint scanners, iris scanners, facial recognition cameras, voice recognition software, and hand geometry readers. These instruments are used to verify an individual's identity based on unique biological traits.
Biometric fingerprint scanners identify you by the ridge patterns mad by your fingerprint. Once the computer has your fingerprint scanned it goes into a database and matches it with your fingerprint to confirm your identity. No ones fingerprint is exactly the same so it is pretty accurate.
A finger scanner is commonly referred to as a fingerprint scanner or fingerprint reader. This biometric device captures and analyzes the unique patterns of ridges and valleys in a person's fingerprint for identification or authentication purposes. Fingerprint scanners are widely used in security systems, mobile devices, and various access control applications.
Fingerprint biometrics are highly feasible and widely used for authentication due to their reliability and security. The technology is well-developed, cost-effective, and offers a high degree of accuracy in identifying individuals based on unique fingerprint patterns. Additionally, fingerprint scanners are compact and can be easily integrated into various devices and systems.
