- A crypto card turns your crypto into regular money at the moment you pay, so the shop only ever receives fiat.
- Most cards are issued by a licensed financial partner, even when an exchange or wallet puts its brand on the front.
- Before applying, check availability in your country, the fee schedule, custody model and how conversion is priced.
A crypto card is a payment card that lets you spend cryptocurrency or stablecoins anywhere a normal card is accepted. It looks and works like any other debit or prepaid card: you tap, insert or type the number online. The difference is what happens behind the scenes in the second or two after you pay.
What happens at the moment of payment
When you tap the card, the merchant’s terminal sends an authorisation request through a card network such as Visa or Mastercard, just as it would for any card. The request reaches the card provider, which checks your balance and approves or declines the payment.
If your balance is held in crypto, the provider sells the amount needed at that moment and converts it into the currency of the purchase. This is the off-ramp step: crypto becomes regular money. Some cards do this conversion when you top up instead, so you are spending a fiat balance by the time you pay.
Either way, the merchant receives ordinary fiat money. The shop never touches crypto, does not need to accept it and usually has no idea where the funds came from.
The main types of crypto card
Crypto cards fall into a few broad models. The label on the card matters less than how your money is held.
- Exchange cards. Linked to an account on a crypto exchange, such as Crypto.com or Bybit. The exchange holds your crypto and converts it when you spend. This is a custodial model.
- Self-custody cards. Linked to a wallet you control, such as Gnosis Pay or MetaMask Card. Funds stay in your wallet until a payment pulls them, usually in stablecoins.
- Prepaid top-up cards. You load a balance in advance, often converting crypto to fiat at that point, then spend the balance like a prepaid card.
- Crypto-backed credit. Less common. You borrow against crypto you deposit as collateral rather than spending it directly.

Who actually issues the card
The brand on the card is often not the company that legally issues it. A crypto exchange or wallet app usually partners with a licensed e-money institution, bank or card programme manager. That partner holds the relevant licence, connects to the card network and is responsible for the fiat side of the transaction.
This matters for two reasons. First, the partner’s licence and location shape which protections apply to your balance. Second, if the partnership ends, the card can be withdrawn in some regions even if the app keeps running. The issuer’s name is normally printed in the small print of the terms or on the back of the card.
What to check before applying
- Availability. Cards are licensed region by region. Confirm yours is supported on our availability page.
- Fee schedule. Look for top-up, conversion, foreign exchange, ATM and inactivity fees, not just the headline offer.
- Conversion pricing. Find out whether the provider adds a spread when it sells your crypto.
- Custody model. Decide whether you are comfortable with a company holding your funds.
- Rewards conditions. Many reward rates depend on holding or locking a token. Read the conditions before treating them as free money.
- Verification. Expect an identity check before the card is issued.

Frequently asked questions
Does the shop know I am paying with crypto?
No. The merchant is paid in its usual currency through the card network, exactly as with any other debit or prepaid card. The conversion happens on the card provider’s side.
Is a crypto card the same as a bank card?
Not quite. Many crypto cards are prepaid or e-money products rather than bank accounts, which can mean different protections. Read the terms to see which entity holds your money and under what licence.
Can I use a crypto card anywhere?
Generally you can use it wherever its card network is accepted, both in shops and online. Some merchant categories or countries may be restricted by the issuer, so check the terms.
