Reviews and ratings for biometrics at credit unions continue to show overwhelmingly positive results whether used to authenticate members at branches or on mobile devices, or employees logging in to workstations.

In the past 30 years, biometrics moved from mostly fingerprinting to many other methods that measure or analyze an individual's voice, speech, face, iris, retina, hand geometry, facial thermography, keystroke dynamics, gait, body odor, veins, foot and palm prints, handwriting (or signature) and even tongue.

Fiserv's Verifast, Palm Authentication technology integrates Fujitsu palm-vein biometrics to improve operational efficiency. In addition, credit unions employing the technology also seek to consolidate and restructure employee identification, allowing them to focus more on member engagement.
