In today’s business landscape, a bank card is more than just a payment tool. For entrepreneurs, fintech companies, and online platforms, it’s a full-fledged financial instrument: from paying freelancers to launching loyalty programs and automating expenses.
To choose the right product, you need to understand the main types of bank cards, their differences, and which business cases they fit best. In this guide, we’ll go through six key categories — prepaid, debit, credit, single-use, reloadable, and corporate — with real B2B use cases.
1. Prepaid Cards
What they are:
A card with a preloaded balance. Non-reloadable prepaid cards can’t be topped up after issuance, while reloadable prepaid cards can be refilled multiple times.
Advantages:
- Not linked to a personal bank account.
- Ideal for short-term usage and controlled budgets.
- Often issued instantly, including as virtual cards via API.
Use cases:

- Payment integration testing: A startup issues prepaid cards to its team for testing overseas SaaS and subscription payments before going live.
- Budget control: A marketing agency gives prepaid cards to staff for ad campaigns with fixed limits, preventing overspending.
2. Debit Cards
What they are:
A card directly linked to a company or user bank account. Transactions are limited to the available balance.
Advantages:
- Direct access to account funds.
- Works for online and offline payments, ATM withdrawals.
- Can offer cashback and rewards.
Use cases:
- Primary payment tool: A fintech wallet uses the WantToPay API to issue virtual debit cards linked to the client’s in-app balance, enabling global spending.

- Marketplace payouts: Sellers receive marketplace earnings on debit cards they can immediately use for ads, supplies, and shipping.
- Instant loan disbursement: A microfinance service issues cards to borrowers right after loan approval.
3. Credit Cards
What they are:
A card with a credit limit provided by a bank or payment operator.
Advantages:
- Spend beyond the available balance with later repayment.
- Interest-free grace period.
- Useful for smoothing cash flow gaps.
Use cases:
- Stock purchases: An online store uses a white-label credit card program to offer partners and customers cards for urgent inventory purchases.

- Project-based funding: A construction company issues temporary credit cards to site managers for materials, closing the limit automatically after the project.
- Partner bookings: A travel agency issues credit cards to agents for hotel and ticket bookings, speeding up client service.
4. Single-use Cards
What they are:
Virtual or physical cards valid for a single transaction or short period.
Advantages:
- Maximum fraud protection.
- Not suitable for subscriptions or recurring charges.
- Often issued instantly via API.
Use cases:
- Secure API payments: A SaaS company uses single-use cards for paying overseas APIs and licenses, ensuring each transaction has unique card details.
- One-time payouts: A service marketplace sends contractor payments to single-use virtual cards valid until funds are spent.
- Testing & verification: A fintech product uses single-use cards to safely test payment gateways in different countries.

5. Reloadable Cards
What they are:
Prepaid cards that can be topped up multiple times.
Advantages:
- Flexible balance management.
- Ideal for recurring payments.
- Works without requiring the end user to have a bank account.

6. Corporate Cards
What they are:
Cards issued to legal entities for business expenses.
Advantages:

Use cases:

- Is spend control required? (limits, MCC restrictions, reporting)
- Which format fits best — virtual or physical?
