What is biometrics?
Biometrics is an automated system of recognizing a person based on the person's physical or behavioral characteristics. It is the same system that the human brain uses to recognize and distinguish one person from another. It is a system that recognizes a person based on "who" the person is and does not rely on "what a person is carrying" or "what a person knows." Things that a person can carry, such as keys and ID-badges, can be lost, stolen, and/or duplicated. Things that a person knows, such as passwords and pin-numbers, can be forgotten, stolen, and/or duplicated. Instead, biometrics relies on "who" a person is-on a unique immutable human characteristic that can not be lost, forgotten, stolen or duplicated. Biometrics, therefore, provides the ultimate level of security, convenience and ease of use.

Why Fingerprints?
Biometric systems in use today include iris recognition, voice recognition, and fingerprint recognition systems among others. Iris recognition is extremely accurate but expensive to implement, and scanning the human eye is a sensitive issue that many find alarming. A typical voice recognition system is affordable but not always reliable since the human voice is subject to change during bouts of illness, hoarseness, or other common throat problems. Fingerprint recognition is considered the best choice for most applications because of its accuracy, speed, reliability, non-intrusive interfaces, and cost-effectiveness. All fingerprints are unique, and that makes them ideal for personal digital identification. Each and every one of our ten fingerprints is unique, different from one another and from those of every other person. Even identical twins have unique fingerprints. The sensors attempt to determine whether a finger is live, and not made of latex (or worse). Detectors for temperature, blood-oxygen level, pulse, blood flow, humidity, or skin conductivity would be integrated.

Why SEIR Optical Method?
Fingerprints can be captured in different ways. Current techniques include optical, ultrasound, or technologies based on semiconductor chips.WittZ introduce sensors from who has pioneered the optical method by introducing the revolutionary Surface Enhanced Irregular Reflection (SEIR) technology, resulting in the most compact and durable optics-based fingerprint recognition systems in the world. The devices also protect against latent and "faked" fingerprints, a feature once considered the exclusive domain of expensive and highly specialized ultrasound technologies. The patent-pending scratch-proof platen of the optical module is another first in the industry; as hard as quartz, the sensor surface requires no special coatings or maintenance and is virtually unbreakable.

What are the advantages of optical fingerprint recognition technology over semiconductor (or chip) -based technologies?
Physical strength. The optics-based system is physically stronger than semiconductor-based systems in terms of impact-resistance, scratch-resistance, weather-durability, and corrosion-resistance. Physical strength is a key factor for versatile outdoor usage. Semiconductor-based systems must apply special surface treatments to protect their inherently weak surfaces. Even then, they are far weaker than optical-prism strength.
Low maintenance costs. Semiconductor chip-based fingerprint recognition systems have higher maintenance costs than SecuGen's system due to their fragility Unlike the optical system, semiconductor-based systems use fragile and expensive parts that are equally expensive to replace and maintain.
No electrostatic problems. Semiconductor systems are inherently susceptible to damage from electrostatic energy, especially in carpeted areas. SecuGen's optical system is immune to electrostatic energy. Static electricity can actually burn out an entire semiconductor-based system.
