Why digital identity is becoming Africa’s most critical tech infrastructure

This highlights that progress in expanding ID ownership is evident and important, yet having an ID is not the same as being able to use it, many people with IDs still face obstacles in leveraging them to access services, transact, or participate fully in the digital economy.

It is clear that identity systems have evolved. Older forms of identification were issued under earlier standards, using different data formats, enrolment methods, or verification rules. As governments and institutions modernise digital infrastructure, these older IDs are not always fully compatible with newer systems.

In practice, this can mean that a person who has been officially identified for decades may still fail digital verification. For example, during a recent verification process, a gentleman in his 50s, who had held a valid national ID for years, was unable to be authenticated because his legacy identity record did not align with the requirements of a newer digital system.

The issue was not fraud or lack of documentation, but a mismatch between old identity records and new infrastructure.

In such cases, exclusion is not caused by the absence of identity, but by how identity systems are upgraded, connected and maintained over time. Digital identity only works when systems are designed to accommodate transition, recognising that people, records and technologies do not all evolve at the same pace.

As identity systems are connected to payments, mobile services, healthcare and government platforms, they stop being stand-alone projects. They become shared infrastructure that needs to work for everyone.

When identity systems work well, services are easier to access and trust increases. When they do not, people are excluded, fraud increases and confidence in digital systems drops. These outcomes depend less on technology labels and more on the choices made when systems are built.

Also, in most identity systems, governments face what appears to be a difficult trade-off. Centralised databases enable fraud detection and de-duplication—but raise legitimate concerns about surveillance and data misuse.

Decentralised approaches protect privacy—but make it harder to prevent duplicate enrollments or detect fraud.

This is often presented as an either-or choice. But it does not have to be. Hybrid architectures offered by companies such as Identy.io can deliver both: on-device verification for daily authentication that keeps biometric templates on the citizen’s phone, with centralised checks activated only when de-duplication is truly needed—and only with explicit consent.

Decisions that seem technical often have real consequences. Some biometric systems do not work well for manual labourers, older people, or people with disabilities. Centralised systems can raise concerns about privacy and misuse of personal data.

Hardware-heavy systems can take years to roll out, delaying access to services for those who need them most. This is where system design becomes critical:

Africa has already shown how digital infrastructure can transform lives. Mobile technology changed how people save, pay, and communicate. Digital identity is now becoming the next foundation.

As identity becomes central to daily interactions, the stakes increase. Systems must be reliable, secure and fair. They must protect people while allowing governments and institutions to deliver services efficiently. Digital identity is no longer a back-office system. It is essential infrastructure.

Software-base capture-using smartphone cameras instead of specialized scanners can reduce deployment timelines from years to months.

These issues are not theoretical. They affect whether a farmer can receive support, whether a small business can access credit, or whether a citizen can safely prove their identity online.

At Identy.io, we see digital identity as public infrastructure that should serve people first. That means designing systems that recognize human diversity, protect individuals, and work in real-world conditions, not just in ideal settings.

What is Good Digital Identity?

From a policy perspective, three principles matter most: inclusion, trust, and adaptability. Inclusion means systems should not exclude people by default. No single method works for everyone, and identity systems need to reflect that reality.

Trust means protecting people from fraud, impersonation, and misuse.

As deepfakes and AI-generated content become more common, verifying that a real person is present becomes essential, not just to protect institutions but to protect individuals from harm.

Adaptability means governments should be able to improve and change systems over time. Digital identity should not lock countries into rigid structures that are hard to update as laws, technologies, and public expectations evolve.

Component-based architectures—where biometric authentication, identity platforms, and digital wallets can be mixed, replaced, or upgraded independently—give governments the flexibility to evolve without starting over. Avoiding vendor lock-in is not just a procurement concern; it is a matter of long-term sovereignty over critical national infrastructure.

“Digital identity should make people’s lives easier, not harder,” says Dr Olajide Olasiyan-Ola, Regional Head for West Africa at Identy.io. “If systems do not reflect real human conditions, they risk excluding the very people they are meant to support.”

Why This Matters Now

And like roads, power, or mobile networks, its value will be judged by whether it expands access, builds trust, and supports long-term development.
