The first six to eight digits of a payment card number can identify the BIN, short for Bank Identification Number. You’ll also see the broader term IIN. Those digits help identify the institution that issued the card and the program it belongs to, and they’re part of how a transaction is routed across networks like Visa and Mastercard.
A BIN belongs to a licensed issuer, usually a bank. BIN sponsorship made it easier for non-bank companies to launch card programs through those licensed issuers. It has become a common model for fintech card programs in markets such as the US and Europe, and it sits behind many of the expense, payroll, and spending cards startups now offer.
In the Philippines, the model is still emerging compared with more established fintech markets. Let’s uncover how BIN sponsorship works, what happened in markets that opened up to fintech card products, and what the current Philippine data suggests.
What is BIN sponsorship?
BIN sponsorship is an arrangement where a licensed issuer sponsors a card program using its BIN and its card network membership. Visa describes the BIN sponsor as “the issuing bank that owns the Bank Identification Number (BIN), which is necessary to access the Visa network”.
The sponsor keeps significant issuer and network obligations. The company running the program typically manages the customer-facing product and relationship, from the card design and app to onboarding and support. That company isn’t free of responsibility, though. Compliance duties are split by contract and by local regulation.
What the company avoids is becoming a bank itself or a direct member of the card network. Depending on the product and the market, it may still need other licenses or approvals.
How BIN sponsorship works
A card program generally involves a banking relationship, an issuer processor and, in most cases, a program manager. Here’s what each party does.
BIN sponsor (the issuing bank): Owns the BIN and holds the card network membership. It oversees compliance with applicable network rules and regulatory requirements, including AML and consumer-protection obligations, and often acts as the settlement agent.
Card network (Mastercard or Visa): Sets the scheme rules. A program has to meet the network’s approval, registration and certification requirements, typically through the sponsor and relevant network partners.
Issuer processor: Typically provides the technology for authorization, card lifecycle management, transaction processing and connectivity. This is often where a card issuing API sits.
Program manager: Runs the card program on the issuing bank’s behalf. Sometimes that’s the fintech itself, sometimes a separate company.
When a cardholder pays, the authorization request travels through the network to the issuer processor. The processor checks the account and the program’s rules, then sends back an approval or a decline. Settlement happens afterward and can involve several parties.
For most businesses, the main advantage is speed. Sponsorship can significantly reduce the time and infrastructure required to launch, although timelines vary by product, market, network and partner.
How fintech card programs grew in other markets
The United States is one of the largest and most established markets for fintech card programs. Corporate card companies like Ramp aren’t banks. Their cards are issued by partner banks, while Ramp provides the customer-facing product and software.
Brazil is a closer comparison to the Philippines: a large, mobile-first market. Brazil’s Law 12,865 of 2013 set rules for payment schemes and payment institutions, including payment accounts. By May 2018 the country had 377 fintechs, with about a quarter in payments and remittances. Nubank was founded in 2013 and launched its first no-annual-fee credit card in 2014, managed entirely through its app. By May 2024 it had more than 92 million customers in Brazil.
Mexico is a case of card products aimed at people outside the traditional system. In a 2021 piece, Lightspeed noted that fewer than 15% of Mexicans had access to a credit card and that 37% had a bank account as of 2019. Stori built a credit card for that group, and at the time more than a million people had started applications. In 2026 it launched a co-branded card with pharmacy chain Farmacias Similares.
Brazil and Mexico show how broader access to financial and payment infrastructure can create room for fintechs to target customers and use cases that traditional providers have historically underserved, from first-time credit users to digital-first businesses.
Where the Philippines stands today
Filipinos already pay digitally at scale. Digital payments made up 52.8% of retail payment volume in 2023, surpassing the BSP’s 50% target for the year.
Account ownership is growing, but mostly through e-money. In a March 2026 survey by Social Weather Stations for the BSP, 58% of adults had a formal financial account. 43% had an e-money account, while 21% had a bank account.
The regulatory side has shifted too. The BSP lifted its moratorium on new non-bank e-money issuer applications effective December 16, 2024. The pause had been in place since November 2021, and the BSP said reopening aims to “promote digital payments, enhance financial inclusion, and foster innovation”.
Strong digital payment use, e-money-led account growth and a reopened path for non-bank entrants create a more favorable setting for embedded financial products. That includes card programs built through licensed issuing partners. The sponsored-card model is still emerging in the Philippines compared with more established fintech markets.
Where Philippine businesses could use sponsored cards
BIN sponsorship isn’t only for fintechs. A business with customers, employees or partners to pay could run a card program too. These are some of the use cases that fit the Philippine market.
Expense cards for smaller companies. Plenty of SMEs still manage spending through cash advances and reimbursements. A platform could give them employee cards with spending limits, real-time tracking and receipts in one place.
Payroll and disbursements. Companies with field teams, riders or contract workers could pay them onto prepaid cards. Whether a worker without a bank account can hold one depends on the product and its KYC requirements.
Co-branded cards. Retailers, telcos and super apps could tie a card to a loyalty program, much like Stori’s pharmacy partnership in Mexico.
A shorter path for fintechs. Working with a sponsor can avoid the need to become a bank or direct scheme member, reducing some of the regulatory and infrastructure requirements involved in building an issuing operation.
The model could also support financial inclusion. Well-designed card programs can expand access to formal payment tools, particularly when they reach customers underserved by traditional financial institutions. With only 21% of adults reporting a bank account in the March 2026 survey, there is a substantial population outside traditional bank-account ownership.
What to look for in a BIN sponsor or card issuing partner
Not every partner fits every program. Before you sign, ask these questions.
1. Is the sponsor licensed and connected? Check that the bank is a principal member of Visa or Mastercard and is in good standing with the BSP.
2. Does it support your card type? Prepaid, debit, and credit programs carry different rules. Virtual and physical cards do too.
3. How strong is the compliance support? KYC, anti-money laundering checks, and transaction monitoring should be built in, not left for you to figure out.
4. How good is the technology? A clean card issuing API, real-time authorization, and flexible spending controls decide how good your product feels.
5. How fast can you launch? Ask for a realistic timeline from contract to first card, and what slows it down.
6. Can it grow with you? Look for room to add new card types, higher volumes, and other markets later.
Some providers bundle the sponsor relationship, issuer processing and program tools behind a single integration. That can simplify the build, so it’s worth asking each partner what they cover and what you’d need to source separately.
