What other unique parts apart from finger print?

Apart from fingerprints, other unique biometric identifiers include iris patterns, which are distinct for each individual and remain stable over time, and facial recognition features, which analyze various facial structures and measurements. Voice recognition is another unique trait, as each person's vocal characteristics, such as pitch and tone, are distinctive. Additionally, DNA profiling provides a highly accurate method of identification, as no two individuals (except identical twins) share the same genetic makeup.
