The introduction of biometric multimodal fusion has helped lead to greater accuracy in biometric authentication, but its adoption rate is still overall fairly low, reports ZDNet Asia.

Biometric authentication today is relying on more methods to determine a person’s identity. Rather than just using fingerprints, identities can be determined through face, iris, vein and body odor. Combining several metrics has led to greater accuracy in verification.

Some reasons for this include the fact that different biometric measures such as voice recognition are still not seeing good adoption rates, even though the technology is mature. Other products, like fingerprint readers, also have slow adoption in the mainstream market due to perceptions that they don’t work well.
