Biometrics are considered more effective in terms of security because they are unique to every individual. This uniqueness arises from biological characteristics such as fingerprints, facial recognition, iris patterns, and voice recognition, which are inherently specific to each person. The fact that these traits are not easily replicated makes biometric systems a robust method of identity verification and authentication.

The effectiveness stems from the difficulty with which someone can impersonate another person based on these unique biological traits, thereby reducing the likelihood of unauthorized access. This uniqueness not only enhances security but also contributes to the convenience of identity checks, as users do not have to remember complex passwords or carry physical tokens.

By relying on distinct physical attributes, biometric systems offer a higher security level than traditional methods, making them a favored choice in various applications, from personal devices to border security and financial transactions.
