The United Arab Emirates has recorded a new milestone in account-to-account payments with the launch of the country’s first one-tap Pay by Bank UAE service. Financial infrastructure provider Lean Technologies and licensed fintech platform Ziina confirmed the deployment on 29 June 2026, positioning it as a shift from single-use instant transfers toward recurring, low-friction payment experiences.
The development sits within the UAE’s live Open Finance regulatory framework, which governs how licensed entities can access and act on customer-permissioned financial data. According to the companies, the service allows Ziina users to link a bank account once and subsequently fund their digital wallets without re-entering credentials or being redirected to external banking portals.
The rollout is relevant to a broad set of stakeholders, including retail consumers, merchants processing digital payments, and financial institutions evaluating how open banking infrastructure translates into everyday transaction volume across the Middle East and North Africa (MENA) region.
What Is Pay by Bank and How Does It Differ From Card Payments
Pay by Bank refers to a payment method that moves funds directly between a consumer’s bank account and a merchant or platform, bypassing card networks such as Visa or Mastercard. Industry data suggests this account-to-account (A2A) model can reduce transaction costs for merchants, since it avoids interchange fees typically associated with card-based processing.
Unlike card payments, which rely on a card number, expiry date, and security code, Pay by Bank transactions authenticate the user directly through their banking credentials or a linked account token. In the UAE, this is enabled through Open Finance regulations that permit licensed third parties, with customer consent, to initiate payments from a linked bank account.
How the Lean-Ziina One-Tap Mechanism Works
The service is built on Lean’s “Deposits” product. Reports indicate the mechanism operates in two stages: an initial account-linking step, in which a Ziina user securely connects a bank account through Lean’s infrastructure, followed by subsequent top-ups that can be executed with a single tap, without repeated authentication or redirect steps.
Underlying Infrastructure
Lean Technologies, founded in 2019, functions as a financial infrastructure provider across the MENA region. The company indicated it has supported over 400 companies, processed more than $5 billion in cumulative transaction volume, linked upward of 2 million bank accounts, and completed more than 3 million account verifications.
Consumer-Facing Layer
Ziina, founded in 2020, is licensed and regulated by the Central Bank of the UAE. The platform reported serving more than 260,000 active businesses and consumers, with a product range that includes peer-to-peer transfers, QR and mobile point-of-sale payments, a multi-asset card compatible with Apple Pay and Google Pay, and a membership tier offering reduced foreign currency fees.
Key Factors Driving Adoption of Pay by Bank Services
Several factors are shaping the transition from one-off A2A payments to recurring, embedded experiences. Financial analysts note that consumer expectations for frictionless digital experiences, shaped by mainstream consumer technology applications, are increasingly extended to financial services. Omar Hamada, VP of sales at Lean, stated that the UAE’s Pay by Bank infrastructure had previously supported only single instant payments, and that the Ziina deployment demonstrates capacity for recurring, low-effort transactions.
Regulatory readiness is a second factor. The UAE’s Open Finance framework, already active, provides the legal and technical basis for licensed entities to build recurring payment products without requiring new regulatory approval for each use case.
Cost, Impact, and Implications for Merchants and Consumers
For platforms such as Ziina, reducing friction at the wallet top-up stage is directly tied to user retention and transaction frequency, since funding the wallet is, according to Talal Toukan, co-founder and head of engineering at Ziina, one of the most common in-app actions. For merchants more broadly, A2A infrastructure of this kind can lower processing costs compared with card-based rails, though the extent of savings will vary by transaction size and merchant category.
For consumers, the primary implication is a reduction in repeated authentication steps. This design also concentrates payment authorization within the linked banking relationship, meaning the security of the one-tap experience is dependent on the integrity of the initial account-linking process.
Risks and Limitations
The service currently applies to wallet top-ups within Ziina’s ecosystem rather than serving as a general-purpose recurring payment standard across all UAE merchants. Broader adoption of one-tap Pay by Bank models will depend on similar integrations by other licensed platforms.
As with any account-linking infrastructure, the model concentrates risk at the point of initial authentication; a compromised linking session could expose recurring transaction capability. Reports do not specify additional fraud-prevention measures beyond the standard authentication protocols governed by Central Bank of the UAE licensing requirements. Regulatory frameworks for Open Finance also remain relatively early-stage compared with more established open banking regimes elsewhere, meaning standards and consumer protections may continue to evolve.
Outlook for Open Finance and A2A Payments in the UAE
Industry participants describe the Lean-Ziina deployment as an early example of a broader shift in the region’s payment infrastructure, from single-instance transactions toward embedded, recurring A2A experiences. Whether this model scales across other UAE fintech platforms will depend on continued regulatory clarity under the Open Finance framework and on further infrastructure investment by providers such as Lean. The companies have not disclosed specific expansion timelines beyond the current Ziina integration.
Conclusion
The launch of a one-tap Pay by Bank service by Lean Technologies and Ziina marks a technical and operational step forward for account-to-account payments in the UAE, moving the market from single instant transactions toward recurring, low-friction payment experiences. The development is grounded in the UAE’s active Open Finance framework and reflects broader regional efforts to modernize digital payment infrastructure. Its longer-term impact on merchant costs and consumer adoption across the wider MENA fintech sector remains to be established.
