How Do Crypto Cards Work?

April 17, 2026

Crypto cards have become one of the most practical ways to connect digital assets with everyday spending. They look and function like regular bank cards, but the balance behind them can be linked to a crypto wallet instead of a traditional account. For many users, this is the first time crypto moves from an investment they hold to money they actually use at checkout.

This article explains what a crypto card is, how it works in the background when you pay, which types exist, and what to check before choosing one.

What Is a Crypto Card

A crypto card is a payment card that lets you spend cryptocurrency at merchants that accept traditional card networks like Visa or Mastercard. The merchant still receives fiat currency, such as euros or dollars, while the card issuer handles the conversion from crypto in real time or draws from a pre-funded fiat balance linked to your crypto account.

Most crypto cards are issued as debit cards rather than credit cards. That means you spend funds you already hold on the platform, not borrowed money. The card itself is usually tied to an account at a crypto exchange or a licensed electronic money institution, which manages balances, conversions, and compliance.

How Crypto Cards Work

From the user's perspective, paying with a crypto card feels identical to paying with any other Mastercard or Visa. In the background, a few extra steps happen within seconds.

  1. You tap, insert, or enter the card details at a merchant. The terminal sends the payment request through the card network, the same way it does for any other card.
  2. The card issuer receives the request and checks your available balance. If the card is linked to a crypto wallet, the system calculates how much crypto needs to be converted to cover the amount in the local currency.
  3. The conversion is executed at the current exchange rate, usually with a small spread or conversion fee. In some models, users pre-top up a fiat balance, and crypto is only converted when they move funds into that balance.
  4. The merchant receives the payment in fiat and completes the transaction. Your account shows the spending, the conversion rate used, and any applicable fees.

This allows crypto card users to pay at ordinary stores, restaurants, or online services without the merchant needing any crypto setup. The network handles the fiat leg, and the issuer handles the crypto leg.

What You Can Pay for With a Crypto Card

A crypto card is most useful in everyday situations where transfers from an exchange to a bank would be too slow or too expensive. The clearest case is daily spending at shops, restaurants, and online stores, since the card removes the need to move funds manually before each purchase. 

The same applies to recurring subscriptions such as streaming services, cloud storage, and software tools, which rely on a stable payment method linked to a reliable balance. 

Travel and cross-border purchases are another frequent scenario, because paying with a crypto card avoids bank wires and the higher FX markups that often apply to international card use.

Many issuers also support ATM cash withdrawals, though availability, limits, and fees depend on the card network and the user's region.

Beyond regular payments, some users treat a crypto card as a treasury tool, keeping most of their funds in crypto or stablecoins and converting only the amounts they actually need at the moment of purchase.

How to Apply for a Tothemoon Card

The Tothemoon card is available to residents of the European Economic Area, and the application process runs entirely inside the Tothemoon account. The steps are straightforward:

  1. Create a Tothemoon account or log in to an existing one.
  2. Complete identity verification. 
  3. Open the card section in your dashboard and submit the card application. 
  4. Activate the card in the app, set your PIN, and start paying at any Mastercard-accepting merchant.

Benefits of Using a Tothemoon Card

The Tothemoon card is designed to make crypto spending feel as simple as using a regular bank card, while keeping the cost structure and limits competitive for daily use.

  • EUR Mastercard acceptance. Works at any merchant and online store that accepts Mastercard across the European Economic Area and internationally, with no separate crypto setup required on the merchant side.
  • Low 0.15% payment fee. One of the lower per-transaction rates among crypto cards, which keeps frequent spending affordable.
  • €100K daily spending limit. High enough for most personal use cases, travel, and larger one-off purchases without workarounds.
  • Flexible funding. Pay directly from a EUR balance or spend from crypto, with conversion handled by the platform at the point of top-up.

Fees and Limits to Consider

Crypto cards are convenient, but their cost structure can vary. Before choosing one, it is worth checking the following:

  • Payment fee. A percentage charged on each transaction, usually 0.1% to 2%. Lower fees matter more for users who spend frequently.
  • Conversion spread. The difference between the market price and the rate applied when crypto is converted to fiat.
  • ATM fees. Cash withdrawal fees and monthly free withdrawal allowances.
  • Foreign exchange fees. Applied when spending outside the card's base currency.
  • Issuance and maintenance fees. Some providers charge for the physical card or for premium tiers.
  • Spending and top-up limits. Daily, monthly, and per-transaction caps vary by provider and user verification level.

Conclusion

Crypto cards turn digital assets into spendable money without forcing users to leave the crypto ecosystem. They route payments through standard card networks while handling conversion behind the scenes, which makes them a practical bridge between long-term crypto holdings and everyday expenses. For users in supported regions, a well-structured crypto card can replace much of what a traditional debit card does, with the added flexibility of choosing when, and how much, to convert.
