Answer:
Taking the example of hand geometry, i-e fingerprints for verification, it is very easy to implement due to the relatively small size of the sensors. As with all digitally stored biometric data, there are risks of data theft.
Explanation:
Fingerprint sensors use scanners to scan the geometry of the patterns on the skin, usually the fingertips. These patterns are unique to each individual to a very high degree, roughly 1:64,000,000 pairs of fingerprints have the chance of being identical. These sensors are relatively easy to install, are cheap, and very user friendly. This makes this technique a very effective method.
Since the data collected by the scanners is almost always stored digitally in a device which is connected to the internet or has access points, there is always the threat of data theft which can result in identity theft and possible fraudulent activities.
