Use of computer accessories in biometric systems biometric systems interpret the physical characteristics of people, something inherent in each individual and non-transferable, to access systems or locations without having to remember key access or carry cards with embedded chips that can be stolen, copied or missing person. These systems are composed of a biometric device that captures the physical traits of the person and a biometric software that analyzes and performs processes to verify that the individual is who he claims to be. Safety, comfort and speed are three features of biometric security that are accelerating the adoption of these systems in the pursuit of total security. These biometric readings are usually based on characteristics of the iris, face, voice, hand or fingerprints. The most common biometric device is currently, the reader of fingerprint recognition (fingerprint reader), since these are also available as an accessory PC, allowing to connect them to the USB port of the computer and then installing the software that usually comes with the reader, for example, replace Windows passwords for the user’s fingerprint, or encrypt files using the footprint as a key.

There are several reader devices of fingerprint, fingerprint reader Nitgen Hamster II and software eNDeSS included with the reader, I recommend choosing one which with its robustness, durability, features small size, sensor detector of fake fingers and efficiency with all kinds of tracks, making it a good choice for any environment both in Office and outdoors. The main use of biometric systems is the control of persons, either on income, the offset within the company passing by control points or on the output. There are a wide variety of biometric solutions: attendance control (replacing the fichadores watches), intermediate control points in sensitive areas of an organization, identification of persons (for clubs and) libraries), identification of individuals to prove their identity as a means of authorisation procedures and formalities. An example of a functional biometric system is the i-Huellas Planigrafo software for control of access and assistance of staff, which is based on the reading of fingerprints. There is a new trend towards devices that do not require contact with the biometric device by user, to avoid failures due to wear or dirt and make more friendly process. In this sense the facial recognition techniques are gaining ground, since using a web camera and biometric capture device and software with ability to detect facial features, turns into a great alternative to regular systems, due to its low cost of implementation and maintenance, as well as also its greater acceptance among users because they are already familiar with web cameras through chat and social networking programs. I-Faces Planigrafo software uses this system for the recognition and identification of the face to carry out control of access and assistance from staff.
