**How do biometric identity verification systems work?**
Biometric identity verification systems work by analyzing unique physical or behavioral traits of individuals to establish identity. These systems utilize technologies such as fingerprint scanning, facial recognition, and iris recognition to capture and evaluate biometric data. Upon enrollment, an individual's biometric data is converted into digital templates stored securely. During verification, the system compares live data against stored templates to authenticate identity. This method enhances security by providing a more reliable, hard-to-fake means of verifying users compared to traditional methods like passwords or PINs.
