Concept
BIN (Bank Identification Number) — the first digits of a card number; issued by payment schemes (Visa, Mastercard) only to their principal members — banks or licensed issuers. BIN sponsorship is access to someone else's BIN: a licensed scheme participant issues cards "on their paper," while a fintech builds a product on top of them without being a Visa or Mastercard member itself.
This is how neobanks and embedded financial products launch debit, prepaid, and credit cards. Card issuance is always a regulated activity (e-money issuance or bank account), so the BIN sponsor both holds the license and is responsible to the scheme.
🍓 Visa/Mastercard membership and responsibility to the scheme remain with the BIN sponsor. The fintech rents access, but the rules of the game — PCI-DSS, monitoring, collateral — are dictated by the sponsor and the scheme.
How It Works
The chain typically looks like this: principal member (bank or issuer — holds scheme membership and BIN) → program manager (runs the program, onboarding, part of compliance) → issuer-processor (technical transaction processing, authorization, ledger) → sponsored issuer, i.e., the fintech with the product, brand, and customer. The fintech can take some roles in-house if it has the license and scale.
Roles and Providers
- Principal member — bank or licensed issuer with Visa/Mastercard membership and its own BINs.
- Program manager — program operator; sometimes the sponsor itself, sometimes a separate company.
- Issuer-processor — technical core of issuance. Notable names: Marqeta, Galileo, Lithic, Highnote, i2c, Thredd.
- Sponsored issuer / fintech — owner of the product and customer experience.
What You Need to Launch
- Legal entity and license. Registered company and, depending on jurisdiction and product, an e-money issuer license (neobank) or neobank (PI) license — or operating under the sponsor's license.
- Compliance infrastructure. KYC/AML, transaction monitoring, dispute handling and chargeback processing.
- Infrastructure. Program manager + issuer-processor combination (or these functions in-house).
- Timeline. Around 3–6 months to launch through an established sponsor and processor.
- Cost. Setup fee, transaction fees, revenue share (portion of interchange), and collateral that the sponsor holds against settlement risk.
⚙️ The sponsor conducts due diligence and continuously supervises the sponsored partner — their license is at stake. Therefore, fintechs face capital, policy, and control requirements comparable to bank onboarding.
Compliance
PCI-DSS for card data processing; scheme rules (branding, limits, disclosures); AML and sanctions screening; settlement cycles and collateral; dispute management and fraud. Violation of scheme rules primarily impacts the sponsor — hence the strict requirements for partners.
Applicable Regulation
Visa and Mastercard card schemes operate under private membership rules, with the licensing regime of the specific market underneath. In the EU and UK, this is the e-money issuance and payment services regime — see agents and passporting in payments; in the US, card issuance goes through a sponsor bank — see BaaS and sponsor banks and the overview of US sponsor banks. The general framework for embedded financial services is in embedded finance (McKinsey: embedded finance and BaaS).
Q/A
Can you issue cards without your own license? Yes, through a BIN sponsor. But the regulated infrastructure (e-money issuance or account) and responsibility remain with the sponsor, while part of the requirements fall on the fintech.
What's the difference between program manager and issuer-processor? Program manager is responsible for the program and compliance, issuer-processor — for technical transaction processing. Sometimes these are different companies, sometimes the functions are combined.
When should you become a principal member yourself? When volumes and margins justify the membership fee, collateral, and your own compliance — typically with large card portfolios.
