The landscape of digital identity is rapidly evolving, with biometrics becoming the cornerstone of trust in remote interactions. This shift is giving rise to a new category of infrastructure that is crucial for investors, enterprises, governments, and individuals alike.
Understanding what constitutes this infrastructure is essential. The National Institute of Standards and Technology (NIST) defines infrastructure as the basic physical and organizational structures needed for the operation of a society or enterprise. In the context of digital identity, this infrastructure enables a wide range of digital operations.
Building Trust Through Digital Identity Infrastructure
Digital identity is not a physical structure but a resource that generates trust, much like how oil generates energy. The infrastructure around digital identity is advancing rapidly, as seen at the Global Digital Collaboration Conference in Geneva. The conference highlighted the progress in digital identity wallets, which can support trust even between parties governed by different jurisdictions.
A collaboration between ISO, IEC, DIN, and the OpenWallet Foundation announced at the conference is making international standards for mobile driver’s licenses and digital ID wallets available for free. This initiative aims to encourage the adoption of standards that define mobile driver’s licenses and extend the mdoc format to other credentials.
National Digital Identity Initiatives
Countries around the world are making significant strides in digital identity infrastructure. In the United States, Login.gov will provide a single sign-on structure for all public services from the U.S. federal government starting in September 2028. This initiative sets a timeline for the transition and leaves space for private sector biometrics providers.
Australia is close to nationwide availability of mobile driver’s licenses, with a launch planned in the Northern Territory by the end of the year. The country has also advanced a privacy framework for digital ID, which is crucial for protecting digital identity as a portable resource.
Investments and Economic Growth
Investments in digital identity infrastructure can lead to dramatic economic growth. Countries that help others with identity infrastructure gain soft power, similar to those that assist with other kinds of infrastructure. For example, Cuba is receiving help from China and the UNDP for its digital government platform, Soberanía. India is backing Sri Lanka’s ambitious digital infrastructure upgrade, including its planned national digital ID.
These investments are not only about technology but also about creating a legal and organizational framework that supports the use of digital identity. The UK’s approach to digital ID, for instance, has raised concerns about the exclusivity of primary digital credentials in the government-issued digital wallet. This could create a two-tier system, according to the Age Verification Provider’s Association (AVPA).
The Role of Digital Public Infrastructure in Economic Development
Historically, economic development has focused on physical capital deepening, such as building factories and infrastructure. However, the ultimate velocity of economic convergence has often been throttled by transaction costs. In low-income economies, verifying citizen identity, establishing trust, executing payments, and enforcing contracts have carried exorbitant friction.
Digital Public Infrastructure (DPI) is a radical architectural inversion that treats digital identity, fast interoperable payments, and data exchange as open public utilities. By collapsing the unit economics of verification, coordination, and settlement to near zero, DPI radically lowers the cost of development. This enables emerging economies to achieve financial deepening and social protection coverage in a fraction of the time it took advanced industrial nations.
The Identity Layer: Slashing Verification Costs
The foundational substrate of modern DPI is universal digital identity, exemplified by India’s Aadhaar, the Philippines’ PhilSys, and Singapore’s Singpass. Traditional paper-based onboarding costs banks and financial institutions between $15 and $20 per customer, requiring up to ten business days to complete.
Open e-KYC APIs collapse this verification cost to just $0.12 per user, while compressing authentication time from ten days to under ten seconds. This 99% cost reduction fundamentally alters the boundaries of viable markets. Financial institutions and fintechs can now profitably service low-income households with micro-savings, micro-insurance, and small-ticket clean energy asset financing.
The Fast Payment Layer: Eliminating Cash Friction
The second pillar of DPI is open, instant, and interoperable payment rails, such as UPI in India, Pix in Brazil, and PromptPay in Thailand. Historically, payment networks in developing economies have been dominated by fragmented, proprietary card networks that extracted high merchant discount fees and restricted cross-network interoperability.
DPI payment systems operate as public utility rails: open-access, zero-fee, and instantly interoperable across any bank or fintech app via simple QR codes or phone numbers. In Brazil, Pix surged to over 42 billion annual transactions within three years of launch, adopted by over 80% of the adult population. In India, UPI processes over 140 billion transactions annually.
Fiscal Efficiency and Direct Benefit Transfers
For sovereign governments, the fiscal dividend of DPI is immediate and transformative. Distributing welfare subsidies, agrarian fertilizer vouchers, and emergency disaster relief through physical cash or paper coupons has historically suffered from catastrophic leakage and bureaucratic extortion.
Fusing digital identity with bank-account-linked fast payments enables Direct Benefit Transfers (DBT) directly into citizen accounts with zero human intermediaries. In India, the “JAM Trinity” (Jan Dhan bank accounts, Aadhaar digital identity, and Mobile connectivity) eliminated over 40 million ghost accounts, saving the central government over $33 billion in cumulative fiscal leakage.
