measures unique characteristics to prevent unauthorised access
Biometric security devices measure unique characteristics of a person
such as finger prints or facial features.
A key advantage of biometric technology when compared to more
traditional solutions, is that it is directly linked to an individual
user and therefore not easily compromised through theft or misuse.
Most biometric systems are easy to use – people do not need
to remember passwords, PIN numbers or carry access control fobs.
If very high security is needed, it is possible to use different
biometric technologies in combination or alongside a more traditional system.
