50 Biometric Innovations

Sherlock Holmes used fingerprints to help ID his suspects and fingerprints were just about the only widely accepted biometrics of the 19th and most of the 20th centuries.

In the 21st century, biometric technologies designed to uniquely identify and serve people are being developed and put to use at an ever increasing pace. Facial recognition became more commonly adopted in the 1990’s. More recently,a number of other technologies have gained varying degrees of acceptance: Hand geometry, vascular, iris, retina, voice, dental, DNA, signature, and gait all play a role. Some examples are featured in this grouping of Trend Hunter finds.
