# How do crypto cards work abroad?

> A crypto card runs on a regular card network and sells your stablecoins at checkout, so the shop gets local currency; fees and protections vary.

A crypto card is a payment card, usually debit or prepaid, that runs on a regular card network and is linked to a crypto account instead of a bank account. When you tap it at a restaurant in Lisbon or Bangkok, the card provider sells enough of your USDC or USDT to cover the bill and pays the shop in local currency, so the merchant never touches crypto. It works anywhere the card network is accepted, but every conversion along the way can carry a fee.

## What happens when you pay

1. **You load the card account** by moving stablecoins into the provider's app or exchange account.
2. **You pay as usual.** The shop's terminal sees an ordinary card payment in its own currency.
3. **The provider converts.** It sells your stablecoins for dollars or for the local currency, at its own rate, and settles with the card network.
4. **You see two records:** a card transaction in the app and a sale of crypto in your account history.

Because the merchant is paid in money, not crypto, a crypto card is often the easiest way to spend stablecoins on a trip. Direct stablecoin acceptance is still rare; see [Can you pay with USDT or USDC while traveling?](https://inyourtravel.com/can-you-pay-with-usdt-or-usdc-while-traveling/)

## Your stablecoins sit with the card company

A crypto card works only because the provider holds your coins. That makes it a custodial wallet, which NIST describes this way: custody of tokens "can be delegated to institutional third-party custodians who hold and safeguard private keys on behalf of users" [source](https://nvlpubs.nist.gov/nistpubs/ir/2021/NIST.IR.8301.pdf). Ethereum.org puts the trade-off simply: "you're trusting that exchange with custody over your funds" [source](https://ethereum.org/wallets/).

In practice:

- **Your relationship is with the card company, not with the stablecoin issuer.** Circle's USDC terms say that holders without a Circle Mint account "are not customers of Circle" [source](https://www.circle.com/legal/usdc-terms).
- **There is no deposit insurance on the coins.** Circle's license disclosures state that virtual currency balances "are not subject to Federal Deposit Insurance Corporation or Securities Investor Protection Corporation protections" [source](https://www.circle.com/legal/licenses).
- **The provider can freeze or close your account** under its own terms, and an issuer freeze hits the provider's addresses too. More on this in [Can USDT and USDC be frozen?](https://inyourtravel.com/can-usdt-and-usdc-be-frozen/)

## What to check before you travel with one

- **Where the card works.** Crypto cards are often limited by your state or country of residence, and some don't work in every country you might visit.
- **The full fee picture:** fees for loading crypto, for each purchase, for foreign currency, and for ATM withdrawals, plus the rate the provider uses when it sells your coins.
- **Which network you deposit on.** When you top up, choose the network the provider lists for USDT or USDC; Tether asks integrators to make it "explicitly clear (both publicly and within their platform) which protocols they support" [source](https://tether.to/en/supported-protocols/).
- **A backup.** Carry a regular card with no foreign transaction fee in case the crypto card is declined or frozen. Our guide to [the best card to use internationally](https://inyourtravel.com/what-is-the-best-card-to-use-internationally/) covers the basics.
- **Taxes.** Each purchase sells crypto. Whether that creates something you need to report depends on your situation; ask a tax professional.

## Watch out for fake "card support"

Scammers pose as support staff for crypto services. The FBI warns that the caller "conveys urgency and may claim there is a problem with the victim's account", then asks for login details or sends a link [source](https://www.ic3.gov/PSA/2024/PSA240801). The FBI's advice: "Do not go to any websites or click on links the caller sends you. Navigate to the official cryptocurrency exchange website separately" [source](https://www.ic3.gov/PSA/2024/PSA240801).

If you top up the card from your own wallet, the deposit itself is a blockchain transfer and can't be reversed, so check the deposit address first in [Stablecoin scanner ACHIVX](https://stablescan.achivx.com/).

## FAQ

**Does the shop know I'm paying with crypto?**
No. The merchant sees a normal card payment in its currency; the conversion happens inside the card provider.

**Can I dispute a crypto card purchase?**
Card purchases may be disputed under the card provider's rules, which differ from one provider to another. Transfers you make to load the card are blockchain transfers and can't be reversed.

**Is money on a crypto card insured like a bank deposit?**
Stablecoin balances are not FDIC-insured; Circle's disclosures exclude FDIC and SIPC protection for virtual currency [source](https://www.circle.com/legal/licenses). Check the provider's own disclosures for what, if anything, is protected.

**Do I need a separate card for USDT and USDC?**
Usually not. Many providers accept both, but each lists which tokens and networks it supports for deposits.
