Every payment starts with a question: who is actually asking for this money to move? For most of the industry’s history, and human history, for that matter, a human was behind the wheel. A real person answered the authorisation question by typing a password, tapping a card, or showing an ID. That is changing now. Software agents are starting to shop, subscribe, and pay on people’s behalf, and the old ways of proving “it’s really me” don’t work for a machine.
This is why digital identity is becoming one of the most important pieces of payments infrastructure, already a hybrid of in-person and agentic payment tools. Digital identity firmly sits behind digital wallets and account-to-account transfers. It is the backbone of know-your-customer (KYC) checks. Besides that, digital ID is the one missing piece that agentic commerce (AI agents transacting on a user’s behalf) needs in order to work safely. Payments companies that still treat digital identity as a compliance checkbox, rather than infrastructure to invest in, risk falling behind as this shift accelerates.
What Is Digital Identity in a Payments Context?
Digital identity is a verified, reusable way of proving who someone (or something) is online. In payments, it usually combines three things: a verified attribute, such as a legal name or date of birth; a credential that carries that attribute, such as a government-issued digital ID or a bank-verified profile; and a method for sharing it securely, such as an app, a token, or a cryptographic signature.
The goal is to replace repeated, manual identity checks, i.e. typing details into every new app, mailing a copy of a passport, with a single verified identity that can be reused and selectively shared. Instead of proving who you are from scratch every time, you prove it once and let trusted parties check it when needed.
How Digital Identity Powers Wallets and A2A Payments
Digital wallets depend on digital identity to work. Before a wallet can hold a card, a bank account, or a stablecoin balance, the provider has to confirm who owns it. That verification step is what allows the wallet to be trusted by merchants, banks, and payment networks later on.
The same is true for account-to-account (A2A) payments, where money moves directly between bank accounts instead of through card rails. A2A payments rely on strong identity checks at both ends of the transaction, since there is no card network sitting in between to catch fraud. For more on how these transfers work and how popular they are, see PaySpace Magazine’s A2A payments statistics.
Digital Identity, KYC, and Fraud Prevention
Know-your-customer rules require banks, payment providers, and crypto platforms to confirm a customer’s identity before opening an account or processing certain transactions. Traditionally, this has meant separate, manual checks at every provider a customer signs up with.
Digital identity makes this faster and cheaper by letting a customer reuse a verified identity across providers, instead of resubmitting documents each time. It also strengthens fraud prevention, since a verified, hard-to-fake identity is more difficult for criminals to impersonate than a password or a static document photo.
The New Driver: Agentic Commerce
The newest pressure on digital identity comes from agentic commerce — AI agents that search, choose, and pay on a person’s behalf. Existing checkout security, like one-time passcodes or CAPTCHA puzzles, assumes a human is present at the point of payment. An AI agent cannot receive a text message or solve a picture puzzle, so merchants and payment networks need a different way to confirm two things. First, that a real person authorized the purchase, and second that the agent acting on their behalf is who it claims to be.
Standards bodies are actively working on this problem. In April 2026, the FIDO Alliance, an industry body known for authentication standards such as passkeys, announced it would form a dedicated working group to develop interoperable standards for how AI agents authenticate and transact, building on early frameworks contributed by major payments and technology companies. This kind of coordinated standards work is what will determine whether agentic commerce becomes trustworthy at scale, in PaySpace Magazine Global team’s opinion, since multiple individual corporate standards would just create another fragmented payment landscape.
Standards and Frameworks to Watch
Several frameworks are shaping how digital identity will work in payments over the next few years:
- Verifiable credentials. A W3C-backed format for digital credentials that can be cryptographically checked without contacting the original issuer every time, making reusable identity practical.
- eIDAS2 and the EU Digital Identity Wallet. Under the European Union’s revised eIDAS2 regulation, every EU member state must offer citizens, residents, and businesses a European Digital Identity Wallet by the end of 2026. From December 2027, regulated sectors including banks, e-money institutions, and payment service providers will be required to accept the wallet as a way to verify identity
- Agent authentication standards. Emerging frameworks from card networks and technology companies aim to let merchants verify that an AI agent is authorized before completing a transaction, an area the FIDO Alliance is now working to standardize across the industry.
Risks: Privacy, Interoperability, and Regulation
Wider use of digital identity in payments brings real risks alongside the benefits. Privacy is the most immediate concern: a reusable identity, if mishandled, could let providers track a person’s activity across services more easily than before. Well-designed systems address this through data minimization, sharing only the specific attribute needed (such as “is over 18”) rather than a full identity record.
Interoperability is another challenge. If wallets, credentials, and standards don’t work across borders and providers, digital identity risks becoming another fragmented system rather than a universal one. And because this is a regulated space, requirements will keep evolving. Thus, payments providers building on today’s standards need to plan for change, not treat any single framework as final.
What This Means for Payments Providers
Wallet-based identity and agentic commerce are still early in the bud, but the standards being set now by bodies like FIDO Alliance and regulators like the European Commission will shape how identity works across the industry for years. Providers that build flexible, standards-aligned identity infrastructure today will be better positioned to support both new wallet regulations and AI agent transactions as they mature. Providers that wait until identity requirements are mandatory will be integrating under pressure, with less room to shape how it’s done.
FAQ
Is digital identity the same as KYC? No. KYC is a regulatory requirement to verify a customer’s identity. Digital identity is the reusable, verified credential that can make KYC checks faster and less repetitive across providers.
Why does agentic commerce need a new identity system? Because existing checks, like one-time passcodes, assume a human is present at checkout. AI agents need a different way to prove they are authorized to act on a person’s behalf.
What is the EU Digital Identity Wallet? It’s a government-backed digital wallet that every EU member state must offer citizens and businesses by the end of 2026 under the eIDAS2 regulation, letting people store and share verified identity credentials.
Will digital identity replace passwords and cards? Not immediately. It’s more likely to sit alongside existing methods at first, gradually reducing how often people need to re-verify themselves manually.
