Countries applying biometrics

Biometrics refers to the automated recognition of individuals based on their biological and behavioral characteristics, not to be confused with statistical biometrics; which is used to analyse data in the biological sciences. Biometrics for the purposes of identification may involve DNA matching, facial recognition, fingerprints, retina and iris scanning, voice analysis, handwriting, gait, and even body odor.

There are multiple countries applying biometrics for multiple reasons, from voting to ePassports.

However, this list is only partial. Multiple other countries in Africa and Asia, including China (Mainland China), collect fingerprints and other biometrics from foreign visitors.
