Choosing the Best Biometric Modality
The success of a biometric system often depends
on choosing the right biometric modality, but it
isnt easy. Careful research that includes
rigorous comparisons of modality strengths and
weaknesses is an important element to help select
the right hardware.

Factors to consider in the comparison

• Specifications
• Convenience
• Usability
• Acceptability
• Effectiveness
• Budget

1. Accuracy
Accuracy is one of the most important aspects to
assess when choosing a biometric modality. It is
based on several criteria including error rate,
False Acceptance Rate (FAR), identification rate,
False Rejection Rate (FRR) and additional
biometric system standards.

2. Anti-Spoofing Capabilities
As biometric recognition systems become more
widespread, strong anti-spoofing protection is a
must have capability for the right biometric
modality.

3. Acceptability
User acceptance is the linchpin of biometric
identification management deployment success.
Understanding which modalities are acceptable
versus those that may cause user acceptance
issues is important.

4. Cost Effectiveness
Depending on the underlying technology and
hardware characteristics, certain modalities may
be more cost effective than others. Its
important to recognize that an initial investment
in biometrics can and is quite often recouped in
a short amount of time to achieve fast return on
investment (ROI).

5. Hygiene
Contact dependent biometric hardware is an
important factor to consider before making an
investment. Many new deployments in industries
that pay close attention to infection control
prefer to use contactless biometric modalities
for hygienic reasons.
