While biometric authentication has long been associated with high-security environments such as government facilities and border control, its adoption is expanding into new sectors
Biometric technologies continue to evolve as organizations look for stronger and more resilient ways to verify identity. For physical security professionals, this evolution is increasingly visible in the rise of multimodal systems that combine multiple biometric identifiers rather than relying on a single method.
While biometric authentication has long been associated with high-security environments such as government facilities and border control, its adoption is expanding into new sectors. Advances in artificial intelligence, improved sensor technology, and stronger spoof detection capabilities are helping drive broader deployment.
At the same time, industry experts note that the technologies delivering the most practical value today remain the established ones, particularly fingerprint and facial recognition.
According to Daniel Asraf, VP of Product Management and Innovation at HID, organizations are increasingly exploring multimodal systems where security requirements demand higher levels of assurance.
“Multimodal biometrics are gaining traction. Industry data shows that adoption is rising, reflecting wider acceptance of combining modalities for higher security and resilience against spoofing,” Asraf said.
Multimodal authentication moves beyond niche deployments
Traditionally, multimodal biometrics were deployed primarily in environments where the risk of identity fraud was particularly high. These included national ID programs, law enforcement databases, and border security systems where accuracy and reliability are critical.
However, the technology is gradually finding broader applications across commercial sectors.
“Research by DiMarket also projects strong growth into the next decade, driven by government ID programs, banking, border security, and criminal justice applications where accuracy and fraud resistance are critical,” Asraf said.
For physical security integrators, this trend signals growing demand for solutions that combine multiple authentication methods within a single system. Rather than relying on a single biometric identifier such as a fingerprint, multimodal platforms combine several modalities to reduce the risk of spoofing and improve accuracy.
Such architectures can also provide redundancy. If one biometric identifier fails to verify the user due to environmental conditions or capture issues, a second modality can still enable authentication.
High-security sectors lead adoption
Despite the expanding interest, multimodal biometrics are still most commonly deployed in sectors where identity security is mission critical.
Asraf noted that organizations are turning to multimodal authentication when the consequences of identity fraud are particularly severe.
“From HID’s perspective, multimodality is valuable for mission-critical use cases where security can’t be compromised,” he said.
Financial services provide a clear example. Banks in several markets are beginning to integrate multimodal biometric verification in customer authentication workflows.
“For example, in markets like Brazil, banks are moving beyond single-factor fingerprint checks at ATMs and adopting multimodal authentication that combines fingerprints with facial recognition,” Asraf said.
These deployments demonstrate how institutions are strengthening identity verification in environments where traditional single-factor biometric authentication may no longer provide sufficient protection.
“These deployments tend to emerge where the security stakes are highest, and organizations see clear value in strengthening authentication beyond a single modality,” Asraf added.
For integrators working in financial, government, and critical infrastructure sectors, this shift may create new opportunities to deploy integrated identity solutions that combine biometric verification with access control systems and identity management platforms.
Established modalities remain dominant
While emerging biometric technologies continue to generate interest, industry experts emphasize that the modalities delivering the most practical value today remain fingerprint and facial recognition.
According to Asraf, these technologies continue to provide the best balance between performance and user experience.
“Today, fingerprint and face remain the strongest modalities — combining accuracy, speed, scalability and user acceptance,” he said.
These characteristics are particularly important for physical security systems that must operate reliably in high-throughput environments such as corporate campuses, transportation hubs, and public facilities.
Biometric systems deployed in such settings must verify identities quickly while maintaining a low false acceptance rate. At the same time, the authentication process must remain convenient for users.
“They consistently provide high security while enabling the frictionless experiences customers expect,” Asraf said.
For security integrators, this balance between security and usability is often the determining factor in whether a biometric solution can be successfully deployed.
AI advancements strengthen core biometric technologies
Much of the recent progress in biometric performance is being driven by advancements in artificial intelligence and machine learning.
AI-based algorithms are improving the accuracy of biometric matching while enabling stronger defenses against spoofing attacks.
“As these mature modalities continue to advance, a growing gap has emerged between what works in practice and what is merely promising on paper,” Asraf said.
Improvements in image processing, sensor quality, and edge computing are also enhancing biometric performance.
Advances in edge processing allow biometric matching to occur directly on the device rather than requiring cloud connectivity. This reduces latency and strengthens privacy protection by keeping sensitive biometric data within the local system.
At the same time, improved spoof detection technologies are helping systems identify attempts to trick sensors with fake fingerprints or images.
“As these mature modalities continue to advance, a growing gap has emerged between what works in practice and what is merely promising on paper,” Asraf said.
For security professionals, these improvements mean that existing biometric technologies continue to become more capable without requiring entirely new modalities.
Emerging modalities face practical challenges
While research continues into new forms of biometric identification, many of these technologies remain difficult to deploy at scale. Iris recognition is a good example.
“Iris recognition, for example, offers strong technical performance but still suffers from poor usability and demanding capture conditions, which is why adoption remains limited,” Asraf said.
Capturing high-quality iris images often requires precise alignment and specialized sensors. In real-world environments where users may be moving quickly or lighting conditions vary, achieving consistent capture can be challenging.
“Similarly, gait, behavioral signatures, and other experimental modalities often attract attention, yet are inconsistent or too intrusive for broad deployment,” Asraf said.
These technologies may still play a role in niche applications, particularly where continuous authentication is required. However, their limitations make them less suitable for mainstream access control and identity verification systems.
Practical deployment considerations for integrators
For system integrators designing biometric-based access control or identity verification systems, the key challenge is balancing security, convenience, and scalability.
The modalities that succeed are those that meet these requirements simultaneously.
“From HID’s perspective, the modalities that succeed long-term are those that balance accuracy with convenience,” Asraf said.
If biometric authentication is too slow, complex, or intrusive, users may resist adoption. Conversely, systems that prioritize convenience without maintaining strong security controls may fail to meet organizational requirements.
This balance becomes even more critical in large-scale deployments where thousands of users interact with the system daily.
Biometric systems must maintain consistent performance across diverse environments, including indoor and outdoor installations, varying lighting conditions, and high user throughput.
For many organizations, combining multiple authentication methods may provide the most practical solution.
Multimodal biometric systems can enhance security while maintaining usability by enabling flexible authentication workflows. For example, users may authenticate with facial recognition during normal operations while using fingerprint verification as a secondary factor when additional assurance is required.
Outlook for biometric authentication
Looking ahead, biometric authentication is expected to remain a core component of identity security systems across many industries.
Growth will likely continue to be driven by sectors where identity verification plays a critical role, including government services, financial institutions, and border control.
At the same time, improvements in AI, edge processing, and sensor technology are likely to further enhance the performance of existing biometric modalities.
For physical security professionals, the key takeaway is that innovation in biometrics is not limited to entirely new technologies. Significant improvements are also occurring within established modalities that already have widespread adoption.
Until emerging biometric technologies can deliver the same combination of accuracy, usability, and scalability, fingerprint and facial recognition are expected to remain the dominant authentication methods.
“Until emerging technologies can meet that threshold reliably and at scale, fingerprint and face will remain the most trusted, deployable, and user-friendly options for secure identity,” Asraf said.
As multimodal systems continue to mature, integrators and security consultants will increasingly need to design identity solutions that combine biometric verification with broader access control and security platforms. In doing so, they will play a key role in helping organizations strengthen identity assurance while maintaining seamless user experiences.
