BIN sponsorship gave fintechs, platforms and programme managers a faster way into card issuing. RS2’s latest whitepaper argues that speed is no longer enough.
The model, which enables companies to issue cards using the BIN and scheme membership of a regulated sponsor, became one of embedded finance’s most useful shortcuts. But recent failures in banking-as-a-service have changed the terms of the discussion. Sponsors, programme managers and technology providers are now under greater pressure to prove where customer funds sit, how ledgers reconcile and who holds responsibility when something goes wrong.
That is the central argument in RS2’s whitepaper Fintech Enablement 2.0: Scaling Payments Without Borders. The company says the next phase of BIN sponsorship will depend on operational control as much as access, bringing together licensing, processing, issuing, acquiring, settlement, reconciliation and reporting within a more tightly governed infrastructure model.
RS2, a cloud-native payments technology provider for issuing and acquiring, describes this as BIN Sponsorship 2.0: a move away from sponsorship as a licence wrapper and towards a full operating model for fintechs, banks, platforms and payment facilitators.
Governance becomes the test
The paper places a focus on the post-SVB and post-Synapse environment, where regulators have sharpened their focus on how sponsored programmes handle reconciliation, customer funds and third-party oversight.
RS2 argues that sponsor banks now need more than confidence in a fintech’s product or growth projections. They need direct visibility over programme-level balances, audit trails, dispute handling, compliance processes and operational dependencies.
The whitepaper sets out three controls it says should sit at the centre of the next sponsorship model: real-time reconciliation, operational segregation and audit-ready reporting.
That means sponsored programmes need clear ledgers, daily reconciliation, defined liability between sponsors and programme managers, wind-down procedures and escalation thresholds for regulators. For sponsor banks, the question becomes less “can this partner launch quickly?” and more “can this partner prove where customer money sits at any point?”
The paper also includes a readiness checklist for fintechs approaching sponsors. RS2 says programme managers should expect to provide 12 and 24-month volume forecasts, anti-money laundering and know your customer frameworks, technical integration plans, dispute handling processes, working capital plans and board-level compliance ownership.
The stack gets harder to split
RS2’s proposed model combines three areas that often sit with different providers: platform technology, processing and licensing.
Its BankWORKS platform covers issuing and acquiring, while RS2 SmartProcessing provides transaction processing, authorisation, clearing and settlement. Beyond by RS2 provides EMI licensing, BIN sponsorship and regulatory enablement.
The paper argues that splitting these functions across several vendors can create extra reconciliation work, duplicated controls and slower operational change. That becomes harder to manage as payment businesses expand across products, markets and customer types.
Radi El Haj, CEO at RS2, said BIN sponsorship is becoming part of a wider payments infrastructure model.
“BIN sponsorship is no longer simply a licence wrapper,” he said. “It is becoming an entry point into a unified payments ecosystem that combines market access, operational control and scalable processing infrastructure.”
The whitepaper identifies four groups likely to use this model: fintechs and digital banks, platforms and marketplaces, payment facilitators and independent software vendors, and banks.
For fintechs, sponsorship still offers a faster route to card products. For platforms and marketplaces, it can support payout cards, merchant acceptance and embedded financial services. For PayFacs and software providers, sponsored acquiring can give more control over merchant onboarding, pricing, settlement and data. For banks, the model offers a way to turn regulatory status into a commercial role in embedded finance.
From access to performance
The paper also tries to move the discussion away from market entry alone.
RS2 estimates that BIN sponsorship through an established sponsor can take eight to 16 weeks from contract execution to first live transaction. A full-stack provider, where sponsorship and processing sit together, can reduce that to six to 12 weeks. Direct scheme membership can take 12 to 24 months.
That time-to-market difference remains a major part of the appeal. But RS2 argues that the bigger commercial test comes after launch, when businesses need to improve approval rates, manage fraud, handle disputes, control settlement and use transaction data more effectively.
The whitepaper cites industry data suggesting that fintechs moving from fragmented multi-vendor infrastructure to unified processing platforms can improve authorisation rates by 1.5 to three percentage points. At $100 million in annual total payment volume and a 1.5% net interchange rate, a two-point improvement in authorisation rates would generate about $300,000 in additional annual net revenue.
It also estimates that multi-vendor integration across issuing, acquiring, sponsor and processor relationships can create 25% to 40% higher operational costs than a unified stack, mainly through reconciliation work, duplicated compliance functions and integration maintenance.
AI raises the infrastructure bar
The final section of the whitepaper links BIN Sponsorship 2.0 to AI and agentic payments.
RS2 argues that payment businesses will need cleaner, real-time transaction data if they want to use AI for fraud decisioning, approval-rate optimisation, routing, merchant performance intelligence, dispute handling and regulatory reporting.
The paper points to several possible use cases, including AI-driven routing based on issuer, time of day, card type and merchant category, as well as automated dispute handling where systems retrieve evidence, assess chargeback reason codes and escalate cases to human reviewers when needed.
Its broader point is that fragmented infrastructure limits what firms can do with AI. If issuing, acquiring, processing, reconciliation and reporting sit across separate systems, the data needed for decisioning becomes harder to use.
“The payments industry is entering a new infrastructure era,” El Haj said. “Businesses no longer want fragmented operating models where licensing, processing and operational control sit across multiple providers. They want infrastructure that allows them to launch quickly, scale internationally and embed payments seamlessly into digital products and platforms.”
RS2 concludes that sponsored access should be treated as the foundation rather than the final objective. In its view, the next phase of BIN sponsorship will depend on whether providers can combine access with governance, data, processing and operational control.
