Biometric systems are commonly used for identity verification in payment systems, using physical traits like fingerprints, face scans, or eye recognition.
Despite their convenience, concerns about the security of biometric systems exist, as once biometric data is compromised, it cannot be changed like a password.
Biometric data is often stored in external servers or the cloud, making it susceptible to hacking and unauthorized access, with no option to reset the compromised data.
There are instances of biometric systems being tricked by fake fingerprints or face masks, highlighting potential vulnerabilities in these systems that could lead to unauthorized access and misuse.
