Generally speaking, biometrics can be defined as a recognition of individuals
based on their behavior or biological unique characteristics. Fingerprints
are taken by pressing a finger against a paper or platen surface on a sensor.
However, due to skin deformations, external influences, irregularities in the
sensor area, etc., we often have incomplete or degraded sample images. When
this happens, many issues within institutions that use this kind of technology
can occur. For example, employees cannot check-in or checkout, which
can sometimes influence important deadlines. As a result of many years of
research, a whole new generation of Touchless 3D scanning devices was
developed and is already available on the market. This new technology of
scanning does not have these issues and it functions in a similar way, although
it has many significant improvements. In this paper, a brief comparison of
original methods, two-dimensional and three-dimensional biometric systems
will be presented. Hardware and software solutions will also be analyzed.
Some of the key problems, such as shadows, background, reflections, sample
irregularities, etc. will be mentioned as well.
