How Crypto Virtual Cards Work
A crypto virtual card works by linking a digital card to your crypto balance and converting that crypto to fiat at the moment you pay. You top up with USDT, a virtual card (number, expiry, CVV) is generated, and when you spend, the provider instantly converts the needed USDT to fiat and settles with the merchant over the Visa network. The merchant receives ordinary currency; you spend from your stablecoin balance. The whole loop happens in seconds.
The end-to-end flow
Here is exactly what happens from funding to checkout.
- 1. Top up — you send USDT to your card balance.
- 2. Issue — a virtual Visa is generated in the app.
- 3. Pay — you check out online or via Apple/Google Pay.
- 4. Convert — USDT is converted to fiat at the point of sale.
- 5. Settle — Visa settles fiat with the merchant.
What happens behind the scenes
The merchant never touches crypto. The card issuer handles the USDT-to-fiat conversion and uses the regulated Visa network to complete the payment exactly like any debit card.
Because USDT is dollar-pegged, the converted amount is predictable, and there is no foreign-transaction markup.
Where fees come in
Crypto cards make money transparently, not through hidden FX.
- A small top-up fee when you load USDT.
- On-chain network fees (paid to the blockchain).
- No FX markup on Kripicard.
