NEW YORK (TheStreet) -- Fingerprint authentication has become the go-to technology for Apple (AAPL) and Samsung (SSNLF) devices. But there are a host of other biometrics -- from eyeball scans to voice and facial recognition -- that are competing to become the dominant security method in the financial-services industry.
“It’s premature to declare fingerprints the winner,” said Gil Mermelstein, a managing director with technology-focused consulting firm West Monroe Partners.

Security experts agree that biometrics will play a crucial role in replacing passwords in everything from brokerages to bank accounts. The question is which technology will prove to be the best.
“Fingerprints are the easiest method today, but all of these methods will grow as banks utilize multiple authentication techniques to achieve higher levels of security,” said John Gunn, a vice president at Vasco Data Security in Chicago.
Why not just crown fingerprints the winner? Experts acknowledge that swiping a finger is straightforward and easy to do. The downside: There just are many times when fingerprints will fail. Perspiration on a finger usually produces false readings. Ditto for when a finger is cold. The durability of fingerprint readers, too, is an unknown, experts said. No one is urging that fingerprints be ignored, just that other approaches warrant investigation.
Which will win? Most experts think there will be a combination of technologies.
"The next winners in biometrics will be multiple biometrics," predicted John Zurawski, vice president at Authentify, a Chicago-based authentication company.
Here's a look at some of the alternatives.
