![]() ![]() Biometric Sensor A biometric sensor works to scan the physical characteristic of a user and then produces electric currents. ![]() This type of scanner is often used for building security, for computer access, security measures, for time clock applications, and many more. Each type of finger print scanner works in a slightly different way. ![]() These biometric scanners come in three basic types, including optic based scanners, radio frequency sensors, and capacitance based sensors. Since the retina is so unique and usually doesn't change, retinal scanning is definitely one of the most reliable biometric options when implementing biometrics type scanners.įinger Print Scanner A finger print scanner uses biometric technology to scan in fingerprints and identify people. Certain degenerative disorders, diabetes, and glaucoma may end up altering the retina, but in most cases, the retina will not change throughout the life of a person. Every person has a retina that is unique because of the structure of capillaries that help to provide blood supply to the retina. Retinal Scanning Retinal scanning is a type of biometric scanning that uses the retina of a person and the unique patterns of that retina to confirm identity. From home locks, to safes, to company security, to time clock systems, you can find a biometrics scanner in more places than ever today. Certain cell phones now have scanners on them to keep unauthorized users from using the phone as well. You can find a new computer mouse that employs a biometric scanner to check fingerprints before allowing access to certain information. Already, many computers are equipped with scanners that check fingerprints before allowing a person on the computer. In fact, you can expect to use a biometric scanners on a regular basis in the future. Biometric Scanner You may be surprised to find that finger scanners are being used more than ever. Even a few banks are beginning to use this security technology, with fingerprint ATMs available in certain parts of the world. Security forces often use scanners to identify criminals. Some airports in certain areas of the world use security scanners to scan the faces of those in the airport to identify and authenticate people in an easier and faster manner. Of course, biometric scanners are employed in many other ways as well. Other companies use biometrics security scanning as a way to keep track of employees, where they are located, and to prevent time card fraud. Some companies use fingerprint scanners to keep track of members, including big gyms. Some biometrics type scanners are designed to read fingerprints, which is a type of scanning that has become extremely popular. Biometric Scanning Today biometric scanning is being used in a variety of different ways. Most scanners are of high quality and will not be affected by the use of contacts or glasses. The iris is the colored portion of the eye and special camera techniques create images of the iris, then turning them into mathematical representations so that an individual can easily be identified. While retina scanners use similar scanning camera technology, iris and biometric retina scans are different. High resolution images are taken with the biometric iris scanners and passed through a biometrics system with high tech software to match up the iris to the person. Biometric Iris Scanners Biometric iris scanners are biometrics scanners that carefully looks at the iris of a person's eye and uses pattern recognition techniques to identify and authenticate that person's identity. They are cost effective, easy to use, and can be used in many different applications with great results. You'll find that these are probably the most popular scanners used for biometrics technology. Once fingerprints are scanned by the biometrics fingerprint scanner, software is used to search prints to authenticate and identify. These devices are specifically designed to scan a person's fingerprint so it can be identified or authenticated against current prints that are in a system. Biometric Fingerprint Scanner A biometric fingerprint scanner is another of the high tech scanners that are commonly being used today. Keep in mind that these eye readers are different from those that scan the iris. Retina patterns cannot be duplicated, the patterns of the retina are very unique, and the false acceptance and rejection rates are much lower with these scanners than with others, such as finger print scanners. One reason that a retina scanner is a top choice is because it happens to be more accurate than biometric type scanners that scan fingerprints. They happen to be one of the newer biometric techniques out there. The samples captured help with various processes, including identification, authentication, and verification. A which is a biometrics security device that is designed to capture retina samples. Retina Scanner One of the scanners available today happens to be a retina scanner. ![]()
