![]() 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. With the cost of adopting iris recognition technology expected to decrease, iris scanning technology is expected to dominate the global market for biometric identity verification and authentication.Retina Scanner One of the scanners available today happens to be a retina scanner. However, iris recognition is widely accepted as a commercially-viable modality compared to retinal scanning. Given the complexity of retinal biometrics, it is hardly surprising that retinal scanning technology only enjoys a low commercial acceptance. ![]() ![]() Retinal scanning technology is mostly deployed in military installations and bases, nuclear facilities, and high-caliber laboratories. Retinal recognition is almost exclusively deployed in applications where extremely high levels of security are a requirement. On the other hand, iris recognition is considered more user friendly as it uses contactless digital photography to precisely verify identity. The acceptance of retinal scans by the general public is extremely low due to its inconvenient and invasive nature. Iris recognition has gained more widespread commercial adoption between the two. Moreover, they also require a person to stay still and avoid extra movements.īased upon the unique physiological characteristics of the eye for identity verification, both retinal scan and iris recognition offer their own list of advantages and disadvantages. It might take more than a few attempts to get the capture process right as eye scanners can be sensitive to reflection. To initiate a reliable iris recognition process, a proper setup is a must. Iris scanners are quite expensive, making them mostly accessible to governments and large corporations. No direct physical contact is required between the person and the camera, making iris recognition completely non-intrusive.īeing one of the emerging biometric technologies, iris recognition comes at a relatively high cost. Iris recognition is an easy-to-use technology, wherein a person only needs to stand still in front of the camera, and the rest is taken care of by the technology behind it. The false acceptance rate and false rejection rate of iris scanning is extremely low, guaranteeing a higher rate of accuracy in identity verification and authentication. Since iris patterns stay practically unchanged throughout a person’s lifetime, iris recognition is one of the most accurate biometric modalities that are commonly deployed. Retinal scans can therefore entail multiple attempts and quite a long time to get the best results in accurately verifying the user. Therefore, retinal scans require a massive amount of cooperation from a user to capture high quality images. This is largely due to having to place the eye into a receptacle while a subtle infrared light is beamed directly onto it. A lot of people assume that a retinal scan can pose a serious health risk to the eye (although unsubstantiated by scientific studies, it still persists). However, there is a negative public perception regarding retinal scanning due to its intrusive nature. Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. Since retinal recognition templates are incredibly small, it is quite fast to confirm the identity of a person. The retina is regarded as one of the most reliable biometric modalities available in the marketplace nowadays.
