Hand and fingerprint scans
One of the most common uses of biometrics in security is hand and fingerprint
scanning. Both are a similar technique, for example both require low storage
space, but the two have some key differences as well. Hand scans are not totally
unique to everyone, unlike fingerprints where no two prints are the exact same.
This makes the latter a more suitable means of biometric security as there is
little margin for error. However, this method has long been associated with
criminal investigating and carries this association with it, meaning some
people, particularly in a workplace environment, may find it uncomfortable.
Hand scanning may be the best option for businesses that don’t require the
highest levels of security such as those needed in airports, but still need a
strong security system.
