Card issuing
Card issuing is the process by which a financial institution or licensed payment company creates and distributes payment cards (credit, debit, or prepaid), allowing cardholders to make purchases and authenticate payments through card network infrastructure.
Card issuing involves multiple participants: the card network (Visa, Mastercard) that sets rules and clears transactions; the issuing bank or licensed EMI that holds the card program and bears financial risk; the processor that authorizes and settles transactions in real time; and the program manager or fintech that designs the product experience and manages cardholder relationships.
Modern API-driven card issuing has disaggregated these layers, allowing non-bank businesses to launch card programs without owning a banking license, by partnering with a licensed issuer and using APIs to control program logic. A fintech building an expense management product can now issue Visa or Mastercard branded virtual or physical cards, define custom spend controls, and receive real-time transaction webhooks, all through API calls rather than legacy bank integrations.
Card issuing programs generate revenue through interchange fees (a percentage of each transaction paid by the merchant's bank to the issuer), while also serving as a strategic product layer that drives user engagement and platform lock-in.
Card issuing transforms payment infrastructure into a revenue-generating product. Interchange income creates a new revenue stream for platforms embedding card products. For corporate use cases, issued cards replace manual expense processes with programmable, auditable spend control.
- Obtaining BIN sponsorship and network licenses requires regulated bank relationships
- Card fraud and chargeback management require real-time decisioning infrastructure
- Compliance requirements vary across card program types and geographies
- Physical card production and logistics add operational complexity
- Spend control logic must be maintained and updated as program needs evolve
A spend management platform issues virtual Visa cards to 500 enterprise clients with per-card spend limits, merchant category restrictions, and real-time transaction notifications. Using API-driven card issuing through Nium, the platform launches in 4 markets within 6 weeks without acquiring a banking license, generating interchange revenue that covers 30% of its infrastructure costs.

Answers you didn't know you needed.
What is the difference between card issuing and card acquiring?
Card issuing creates cards for cardholders to spend with. Card acquiring enables merchants to accept card payments. They sit on opposite sides of a transaction: the issuer's bank authorizes the payment, the acquirer's bank receives it on the merchant's behalf.
Do I need a banking license to issue cards?
Not directly. Through BIN sponsorship, a licensed bank or EMI (like Nium) sponsors a card program, allowing a non-bank entity to offer cards under the licensed institution's regulatory umbrella.
What is interchange revenue in card issuing?
Interchange is a fee paid by the merchant's bank to the card issuer on each transaction, typically 0.2–2% of the transaction value depending on card type and market. For businesses running card programs, interchange income can be a significant revenue stream.
What is the difference between virtual and physical cards?
Virtual cards exist only as card credentials used for online or contactless payments. Physical cards are issued as plastic for in-person transactions. Both can be issued programmatically through Nium's API.
