Biometrics are much more complex than just dactyloscopy (fingerprint identification) but at the root, fingerprints are quite easy to track. That's what makes them the basis for many biometric devices.
The technology has progressed to the point at which it may be utilized in technical applications, like a door lock or time clock. However, let us concentrate on the safety side of things.
