Biometrics is changing the way that business leaders and agency executives think about security. In the digital age, tech engineers and IT managers are devising all kinds of new ways to implement biometrics into their daily routine.

Meanwhile, a number of different news outlets have reported that biometrics is gradually finding its way to smartphones as well. And as the "bring your own device" strategy, or BYOD, becomes a more central part of business models, this development could become a major facet of biometrics.

Face and voice recognition on the way
USAA, a financial services company based in San Antonio, has begun using facial and vocal recognition technology for its member base through a mobile app, according to American Banker. However, each form of recognition has its place in relation to specific settings.

"If I'm at a Spurs game, and I take out my mobile phone and try to use voice recognition, it's not going to work because I have 100 people around me screaming and yelling at the same time," Rick Swenson, fraud operational excellence and strategic initiatives executive with USAA, told the news outlet. "What will work at a Spurs game is my face."

Mobile biometrics on the rise
Acuity Market Intelligence recently noted that by 2020, smartphones will feature embedded biometric sensors as a standard, NFC World reported. This emergence would lead to a $33.3 billion per year market for biometrics.

"Biometrics are a natural fit for the smart mobile devices we hold onto nearly every waking hour," Maxine Most, the principal of Acuity Market Intelligence, told the news outlet. "The explosion in the use of smart devices over the past five years along with anticipated growth over the next five, especially in developing economies where sub $100 smartphones have begun to alter the mobile landscape, will bring biometrics into the daily lives of half the global population."

Biometrics ensure secure business operations
Biometrics is undoubtedly becoming more advanced as the technology spreads throughout the business world. But what makes it so useful?

With advanced security systems, biometric technology mandates the use of unique physical characteristics such as facial features, voice patterns and fingerprints to ensure access control for only a limited number of people. It's been shown to be one of the best ways to keep hackers at bay. And in an era of growing trepidation about cyberattacks, this technology is of the utmost importance. Meanwhile, dual-access systems are an even more advanced level of biometric security that call for two distinct IDs used simultaneously.
