Introduction to Token.io’s New Feature

Token.io, which positions itself as a leading Pay by Bank infrastructure provider, has launched a new capability called Account on File aimed at improving the usability—and therefore the commercial performance—of account-to-account (A2A) payments in online checkout.

The premise is straightforward: Pay by Bank has clear economic and operational appeal for merchants, including faster settlement and lower processing costs. But the method has often struggled with a familiar e-commerce problem: friction. Each additional screen, redirect, or selection step can increase abandonment, particularly in high-frequency scenarios such as everyday e-commerce purchases or account top-ups.

Token.io’s new feature is designed to address that gap by making Pay by Bank feel closer to the convenience consumers associate with stored card payments. Sam French, Token.io’s director of product, framed the issue in conversion terms: “For high-frequency transaction scenarios, every extra step costs you customers.”

The company says Account on File is delivered through Token.io’s latest API, allowing payment service providers (PSPs) and merchants to deploy it “at speed and scale with minimal effort”—a notable claim in a market where implementation complexity can slow adoption even when the value proposition is clear.

Reducing Pre-Authorization Checkout Friction
In many Pay by Bank checkouts, the “friction tax” shows up before the user ever authorizes the payment: selecting a bank, sometimes selecting an account, and navigating redirects/app-to-app handoffs. “Account on File” targets that specific pre-authorization friction by remembering the user’s prior bank/account choice—so the returning journey starts closer to “confirm” than “set up.”

Understanding the Account on File Functionality

Account on File is explicitly modeled on the “Card on File” pattern that consumers already understand: a payment method that can be used without repeating the same setup steps each time. In Token.io’s implementation, the feature securely remembers a consumer’s chosen bank and account(s) and then presents these by default for future Pay by Bank transactions.

In practical terms, that means the first Pay by Bank payment still looks like a typical open banking flow: the consumer selects Pay by Bank, chooses their bank, authenticates, and completes the payment. The difference comes on subsequent visits. Instead of forcing the user to re-select their bank and account, the checkout can pre-populate those choices.

Token.io says this can remove steps from a “typical Pay by Bank experience.” In checkout design, two steps can be the difference between a payment method that feels “worth it” and one that feels like a detour—especially on mobile, where redirects and repeated selection screens can be more punishing.

The company’s messaging also emphasizes that Account on File can make Pay by Bank “a one-tap experience for returning payers,” positioning it not merely as an incremental UX improvement but as a bid to make A2A payments competitive with the best-known convenience benchmark in online payments: stored cards.

Streamlined Pay by Bank Flow
First payment (new payer)
1) User selects Pay by Bank at checkout.
2) User chooses their bank.
3) User authenticates/authorizes in their bank environment.
4) Payment completes.
5) A tokenized reference to the chosen bank/account(s) is created so the choice can be recalled later.
Returning payment (same payer)
1) User selects Pay by Bank.
2) Checkout shows the previously selected bank/account(s) by default (no re-selection step).
3) User proceeds to authenticate/authorize.
4) Payment completes.
Checkpoint to watch: Account on File reduces selection steps, but the bank authorization step still needs to be smooth across devices for the “one-tap” feel to hold.

Benefits of Account on File for Merchants

Account on File is pitched as a conversion and efficiency feature, but its merchant value proposition sits on two layers: (1) improving the Pay by Bank user journey and (2) amplifying the underlying benefits merchants already associate with A2A payments.

Token.io argues that by reducing friction, merchants can expect fewer drop-offs and more completed payments, particularly among returning customers. That matters because repeat buyers are often where e-commerce profitability is made—yet they are also the segment least tolerant of slow or unfamiliar checkout flows.

Beyond conversion, Token.io links the feature to the broader A2A benefits merchants seek: faster settlement, lower processing costs, and improved cash flow. Those advantages exist without Account on File, but the feature is positioned as a way to unlock them at higher volume by making Pay by Bank easier to choose repeatedly.

In other words, the feature is not just about making Pay by Bank “nicer.” It is about making it habit-forming—a stored preference that can compete with the default behavior of reaching for a saved card.

Faster Checkout Experiences

Speed at checkout is rarely about raw seconds alone; it’s about perceived effort. Token.io’s claim that Account on File removes steps targets a common pain point in Pay by Bank flows: repeated bank selection and account selection.

By remembering the consumer’s previously chosen bank and account(s), the checkout can present those options immediately, reducing the number of screens and decisions required to complete a payment. Token.io translates that into tangible outcomes: fewer clicks, faster checkouts, and fewer drop-offs.

This is particularly relevant for high-frequency use cases, where the same customer may return often, and where the friction of repeating setup steps can quickly outweigh the perceived benefits of paying directly from a bank account.

Sam French’s framing is blunt but familiar to anyone who has optimized funnels: every extra step “costs you customers.” Account on File is designed to remove those steps without changing the underlying Pay by Bank rails, effectively compressing the journey for returning users into something closer to a “tap and confirm” experience.

Increased Conversion Rates

Token.io’s launch announcement is explicit about the commercial goal: increasing checkout conversion rates. The logic is consistent with standard funnel dynamics: fewer steps generally mean fewer opportunities for abandonment.

Account on File is positioned as a way to make Pay by Bank competitive with stored card experiences by making it feel “as effortless as using a stored card.” That matters because conversion is not only about trust and price; it’s also about familiarity. Consumers already understand what it means when a checkout “remembers” them.

Token.io also ties conversion improvements to a broader merchant incentive: if Pay by Bank becomes easier to complete, merchants can route more volume through A2A payments and capture the associated benefits—lower processing costs and faster settlement—more consistently.

The company’s messaging suggests a reinforcing loop: better UX drives higher Pay by Bank usage; higher usage increases the merchant’s realized savings and cash-flow gains; and those gains justify further investment in Pay by Bank as a primary method rather than a secondary option.

Security Measures in Tokenization

Token.io places tokenisation at the center of Account on File, positioning security as the enabling mechanism for convenience.

What changes operationally for PSPs and merchants

From an implementation perspective, the announcement frames Account on File as an API-delivered capability that lets PSPs and merchants reduce repeat-checkout friction without storing sensitive bank details themselves. Practically, the value is concentrated in returning-user flows: pre-populating the previously selected bank and account(s) removes selection steps, while tokenisation is the mechanism that allows “remembering” without exposing underlying account data. The core idea is familiar from card tokenisation: replace sensitive account details with a non-sensitive token that can be used to reference the user’s bank account(s) in future transactions without exposing the underlying data.

In Token.io’s description, this approach means merchants do not need to store consumers’ sensitive bank details directly. That matters for two reasons. First, it reduces the risk profile of storing high-value financial identifiers. Second, it supports the product promise that consumers “never sacrifice peace of mind for convenience.”

Token.io also leans on the broader trust framing of Pay by Bank: consumers pay “straight from their bank accounts,” with “bank-grade security and control.” While the company’s announcement does not enumerate every control in the flow, it emphasizes that Account on File is designed to preserve the security posture of Pay by Bank while reducing friction.

The strategic point is that tokenisation is not presented as an optional add-on; it is the mechanism that makes “remembering” a bank account acceptable in a regulated, security-sensitive environment. Without tokenisation, “Account on File” would risk sounding like “store my bank details,” which is precisely the kind of proposition many consumers and merchants would hesitate to adopt.

Tokenized Bank Selection Recall
What’s stored (to enable “remembering”)
– A tokenized reference that points to the user’s previously selected bank and account(s).
Where the value shows up
– In returning-user checkout: the bank/account choice can be pre-populated so the payer doesn’t repeat selection steps.
What’s not stored by the merchant (per Token.io’s positioning)
– The consumer’s sensitive underlying bank account details are not stored directly by the merchant; tokenization is used instead.
What still happens every time
– The payer still authorizes the payment in their bank environment (the “remembered” part is the selection, not the authorization).

Impact on Payment Service Providers (PSPs)

Token.io’s launch is aimed as much at PSPs as at merchants. In the company’s framing, Pay by Bank is becoming “table stakes” for PSPs—supported by Token.io’s own research indicating that 90% of PSPs offer or plan to offer Pay by Bank in the near term.

If Pay by Bank is no longer a differentiator by itself, then the competitive battle shifts to experience: who can make it easiest, fastest, and most reliable for merchants to deploy—and for consumers to use repeatedly.

Account on File is positioned as a differentiating layer PSPs can add on top of Pay by Bank rails. By enabling returning users to see their previously selected bank and account(s) pre-populated, PSPs can offer a Pay by Bank journey that competes more directly with stored card flows—without requiring merchants to build bespoke “remember me” logic around bank selection.

Token.io also emphasizes implementation practicality: the feature is intended to be rolled out “at speed and scale with minimal effort.” For PSPs, that matters because the cost of integrating and maintaining multiple payment experiences can be as decisive as the revenue upside.

In effect, Token.io is offering PSPs a packaged answer to a common merchant question: “Pay by Bank is cheaper, but will it convert?” Account on File is designed to let PSPs respond with a credible UX improvement rather than a promise.

PSP Momentum Toward Pay by Bank
Adoption pressure on PSPs (as framed by Token.io)
– Token.io research claim: ~90% of PSPs “offer or plan to offer Pay by Bank” in the near term.
Why that matters for product strategy
– If many PSPs can offer Pay by Bank, differentiation shifts to repeat-user UX (e.g., fewer steps) and rollout practicality (API availability, time-to-integrate).
Source context
– The “90%” figure is Token.io-reported research cited in launch coverage (Open Banking Expo / Token.io press messaging).

Consumer Experience with Account on File

For consumers, the promise is convenience without giving up control. Token.io says Account on File makes Pay by Bank “faster and more convenient” by showing returning users their previously selected bank and account(s) by default.

This pre-population does two things at once. It reduces time and effort, and it reduces cognitive load—users don’t have to remember which bank option they used last time or navigate a list again. The experience is meant to feel familiar: “as effortless as using a stored card.”

Token.io also frames the feature as improving confidence, not just speed. The company highlights “bank-grade security and control,” and stresses that tokenisation prevents merchants from storing sensitive account details directly. The consumer benefit is positioned as peace of mind: the system can “remember” the account without exposing it.

This matters because Pay by Bank adoption is not only a product design challenge; it is a trust challenge. Consumers may be comfortable paying from their bank account, but they are not necessarily comfortable with the idea of their bank details being stored by every merchant they buy from. Token.io’s approach attempts to separate those concerns: store a token, not the details.

The net effect is a Pay by Bank journey that aims to be both repeatable and reassuring—two qualities that stored card payments have historically dominated.

Faster Repeat Pay by Bank
What a returning payer typically experiences with Account on File
– Sees Pay by Bank as usual at checkout.
– Sees their previously selected bank (and, where relevant, account) already selected by default.
– Skips re-finding their bank in a long list.
– Proceeds to authorize in their bank app/web flow.
– Completes payment and returns to the merchant confirmation.
Quick expectation-setter
– “Remembered” = the selection is pre-filled; authorization still occurs each time.

Market Trends and Adoption Rates

Token.io’s launch lands in a market it describes as moving from experimentation to expectation. The company points to Pay by Bank becoming mainstream in the UK and Europe, and positions Account on File as a feature that addresses one of the remaining barriers to broader usage: repeat-payment friction.

Two adoption signals stand out in the company’s cited research and commentary:

• Token.io research indicating 90% of PSPs offer or plan to offer Pay by Bank in the near term.
• Separate industry survey results cited in related coverage suggesting 91% of respondents observed a significant increase in merchant demand for Pay by Bank in 2025, with expectations of continued growth.

Those numbers don’t prove universal adoption, but they do suggest a market where Pay by Bank is increasingly part of the default roadmap for PSPs and a growing priority for merchants.

In that context, Account on File reads as a competitive response to a predictable market shift. Once many providers can offer Pay by Bank, the differentiator becomes whether the experience can match the convenience of cards—especially for returning customers, where stored credentials have long been a conversion advantage.

Token.io’s own positioning reflects that: it is not pitching Account on File as a niche feature, but as a step toward making Pay by Bank “one-tap” for repeat users—an attempt to set a new baseline for what “good” looks like in A2A checkout.

Challenges in Implementing Pay by Bank

Even with improved UX, Pay by Bank adoption faces structural and operational challenges. One is ecosystem reach: for Pay by Bank to feel ubiquitous, bank participation is critical. If consumers can’t reliably find their bank in a flow—or if experiences vary widely between institutions—then friction returns, regardless of how well the PSP has designed the checkout.

Another challenge is consumer understanding and trust. Token.io’s messaging leans heavily on security and control, but merchants and PSPs still need to communicate clearly what Pay by Bank is, what it isn’t, and why it’s safe. Confusion at checkout can look like friction, and friction can look like risk—both of which reduce conversion.

There is also the practical reality that Pay by Bank flows often involve redirects or app-to-app handoffs. Account on File reduces steps like bank and account selection, but it doesn’t eliminate the need for authentication and authorization in the banking environment. That means the “one-tap” aspiration depends on how smoothly the remaining steps execute across devices and banks.

Finally, implementation speed matters. Token.io says Account on File is available via its latest API and can be rolled out with minimal effort, but PSPs still need to integrate, test, and support the feature across merchant portfolios. In payments, “minimal effort” is relative—especially when multiple stakeholders (merchant, PSP, bank) shape the end-to-end experience.

Planning for Real-World Friction
Practical friction points to plan for (and how teams typically mitigate them)
– Bank coverage/consistency varies → Offer clear fallback paths (e.g., card) and monitor bank-level drop-off.
– Redirects/app-to-app handoffs can break on mobile → Test across devices/browsers and keep return-to-merchant handling robust.
– “One-tap” can be misunderstood → Set expectations in UI copy: selection is remembered; authorization still happens.
– Returning-user recognition isn’t universal (new device, cleared cookies, etc.) → Treat Account on File as an optimization, not the only happy path.
– Integration is “minimal” only after good QA → Plan for sandbox testing, edge cases, and support playbooks before scaling.

Conclusion: The Future of Pay by Bank with Token.io’s Account on File

Enhancing User Experience and Merchant Efficiency

Account on File is Token.io’s attempt to close a long-standing gap: Pay by Bank can be economically attractive, but it has not always been as convenient as stored cards for repeat purchases. By remembering a consumer’s chosen bank and account(s) and presenting them by default, Token.io is betting that fewer steps will translate into fewer drop-offs and higher conversion—particularly in high-frequency scenarios like e-commerce and top-ups.

For merchants, the upside is not only conversion. It is the ability to realize more of the underlying A2A benefits Token.io highlights—faster settlement, lower processing costs, and improved cash flow—by making Pay by Bank a method customers will choose again and again.

The Role of Tokenization in Secure Transactions

Tokenisation is the feature’s enabling technology and its trust anchor. By replacing sensitive account details with a non-sensitive token, Token.io aims to deliver “remembered” convenience without pushing merchants into the business of storing bank details. That separation—convenience on the surface, reduced exposure underneath—is central to making Account on File viable at scale.

Looking Ahead: The Evolution of Payment Methods

Token.io’s own research suggests Pay by Bank is quickly becoming standard for PSPs, and broader survey signals point to rising merchant demand. In a market where Pay by Bank is increasingly expected, differentiation shifts to execution: the smoothness of the flow, the repeatability of the experience, and the confidence it inspires.

Account on File is a clear statement about where that competition is heading. If Pay by Bank is to compete with cards not just on cost and settlement speed, but on habit and convenience, then “one-tap for returning payers” is the benchmark Token.io is trying to make real.

This perspective is informed by Martin Weidemann’s work building and scaling payment and fintech systems in regulated, multi-stakeholder environments across the Americas, where small reductions in checkout friction and clearer security boundaries often determine whether a payment method becomes repeat behavior.

This article reflects publicly available launch coverage and vendor statements available at the time of writing about Token.io’s “Account on File” feature and Pay by Bank adoption. Rollout specifics—such as bank coverage, user experience, and integration requirements—may differ by provider, merchant implementation, and the consumer’s device or bank journey. Any market statistics cited should be treated as directional rather than definitive, and details may evolve as new information emerges.
