Iris scanning is a biometric technology that identifies individuals by analyzing the unique patterns in their iris, the colored part of the eye. This method uses a camera to capture a detailed image of the iris, which is then converted into a digital template for comparison. Because each person's iris patterns are distinct, this technique is highly accurate and secure. Iris scanning is commonly used for security purposes, such as in smartphones, airports, and government facilities. It offers a quick and non-invasive way to verify identity, making it a popular choice for access control and authentication systems.
