If you use a password to secure your laptop, your password might be able to be solved by someone else. However, if you use the biometric system, it would be very difficult to solve.
This system is capable of detecting fingerprints or retina, so that only the owner can open the lock. By using biometric systems, other people will not be able to open the existing system on your laptop without having your fingerprints or retina.
That is why, some computer manufacturers are now offering laptops that are built with biometric fingerprint identification systems. This system is useful to prove the authenticity of the user based on the similarities of fingerprints that are stored when the software is first run.
