Virtual credit card processing is growing fast - digital-only cards are projected to expand by more than 300% over five years, outpacing traditional plastic. For anyone offering merchant services, understanding how it works is a chance to bring businesses a more secure, controllable way to pay and earn residuals doing it.
How it works
A virtual card is a digital-only card - a 16-digit number, expiry date and CVV issued by a provider such as Stripe or Brex. The buyer uses it to pay online or by phone, the processor routes the data to the acquiring bank, the issuing bank approves, and the merchant receives funds just like a normal card sale. Four players make it happen: the merchant, the virtual card provider or issuing bank, the payment processor, and the acquiring bank.
Two types of cards
- Single-use cards - created for one transaction, then they expire automatically. Great for fraud prevention and one-off vendor payments.
- Multi-use cards - reusable within set limits, used for recurring or ongoing spend (Brex, Ramp, Divvy, Amex virtual cards).
Why businesses switch
Virtual cards use tokenization and encryption, so a stolen number is useless. They can be generated instantly and automated for recurring payments, and they let a business set spending limits, restrictions and expiry dates for tighter control. Some providers even support Level 2 and Level 3 processing that can lower interchange fees.
Watch-outs
Not every merchant or POS accepts virtual cards without extra configuration, fees vary between providers, integration with accounting systems can take setup, and PCI DSS compliance still applies. Weigh those factors before recommending a processor like Stripe, Brex, Payoneer or Bill.com.
