An Iris Scan is a biometric technology that uses the unique patterns in the colored part of the eye, known as the iris, for identification and authentication. This method captures a high-resolution image of the iris, which is then analyzed to create a digital template. Because each person's iris patterns are distinct, this technology is considered highly secure and reliable. Iris scanning is commonly used in various applications, including security systems, mobile devices, and border control. It offers advantages over other biometric methods, such as fingerprints or facial recognition, due to its accuracy and resistance to forgery.
