As the digital economy accelerates, payment technologies continue to evolve. Among the most powerful tools reshaping financial control and risk management are virtual cards and single-use cards. While both are designed to enhance security and streamline corporate spending, they serve different purposes.
This article explains their key differences, best use cases, and how platforms like Buvei optimize both types to meet modern business needs.
What Is a Virtual Card?
A virtual card is a digitally issued payment card that functions like a traditional credit or debit card. Issued by banks or fintech platforms, it comes with a 16-digit card number, expiration date, and CVV—just like a physical card—but exists only in digital form and is typically tied to a funding source or budget.
Virtual cards are reusable and can be configured with rules for:
-
Recurring subscription payments
-
Departmental or employee spending
-
Advertising budgets (e.g., Google, Meta)
-
B2B supplier payments
Platforms such as Buvei, Ramp, allow businesses to instantly generate multiple virtual cards with custom permissions—like spend limits, expiration dates, or merchant restrictions.
What Is a Single-Use Card?
A single-use card (also known as a disposable card) is a subtype of virtual card designed for one-time use. It becomes invalid immediately after its first transaction, making it ideal for minimizing fraud risks.
Common use cases include:
-
Payments to new or untrusted vendors
-
Online bookings (hotels, flights, etc.)
-
Payouts to temporary contractors or consultants
-
Trial-period subscriptions
Platforms like American Express Go, Divvy, and Emburse offer single-use cards to reduce unauthorized charges and increase transaction security.
