How do cryptocurrency cards work? A comprehensive guide for new users

Introduction: From Idea to Implementation

Satoshi Nakamoto invented Bitcoin not only as an investment tool but as a global digital payment system that individuals can use in their daily lives. Today, this idea has evolved into digital currency cards, one of the most practical ways to convert your digital assets into real goods and services. Instead of holding your cryptocurrencies in a digital wallet, you can now spend them directly when shopping at stores, restaurants, and service providers that accept these cards.

What Are Digital Currency Cards?

A digital currency card is a payment tool that links your account on a cryptocurrency exchange platform or your digital wallet to a global payment system. It operates similarly to traditional debit cards, but instead of spending local fiat currency, you spend the digital assets stored in your account.

When you use the card for a purchase, the merchant does not receive the digital currency directly. Instead, the service platform converts the amount of digital currency into the accepted local currency at the moment of the transaction, then transfers this amount to the merchant. This instant conversion means the merchant receives their money in the accepted international currency (dollars or euros, for example), while you lose an equivalent amount of your digital assets.

Giant companies like Visa and Mastercard issue digital currency cards in collaboration with specialized platforms, ensuring these cards are accepted at millions of point-of-sale locations worldwide.

How It Works: A Practical Example

Suppose you have $500 worth of BNB in your card wallet. You go to a restaurant and want to pay a $100 bill. When you insert the card and approve the transaction:

1. The card service sells $100 worth of your BNB at the current exchange rate
2. Converts the amount into the local currency and credits your card account
3. Immediately transfers the amount to the restaurant
4. You are left with $400 worth of BNB in your wallet

All of this happens within seconds. You can also use these cards at ATMs to withdraw local fiat currency directly.

Main Differences Between Card Types

Prepaid Digital Currency Card

You need to deposit digital assets into it before spending (like a debit card). You cannot spend more than you have. Features include no debt and full control over spending.

Digital Currency Credit Card

Provides a credit limit similar to traditional credit cards. You pay the bill later in the accepted local currency while earning rewards or points from your digital currencies on your purchases.

Regular Debit Card vs. Digital Currency Card

The main difference is the source of funds. A debit card contains an accepted local currency, while a digital currency card contains digital assets that are converted at each purchase.

Key Benefits of Using Digital Currency Cards

1. Ease of Daily Use

Without a card, you would need to manually convert your digital currencies into local fiat and transfer the amount to your bank account — a process that can take days. The card shortens this to seconds.

2. Retaining Your Digital Assets

You don’t need to convert all your currencies in advance. The card converts only the necessary amount at the time of purchase, allowing your remaining assets to continue earning market profits.

3. Rewards and Cashback

Most cards offer cashback or special discounts on subscriptions and well-known services. This is similar to rewards programs in traditional credit cards.

4. Security and Protection

Deposited funds are subject to strict security standards and protection from licensed platforms.

Risks to Be Aware Of

Price Volatility

If you add Bitcoin or Ethereum to your card, their value in the accepted local currency may fluctuate continuously. You might find that your actual balance differs from what you expect due to exchange rate volatility.

Tax Implications

In many countries, spending cryptocurrencies is considered a taxable event — whether you buy a coffee or a car. If you realize profits or losses on your currencies before spending them, you will need to account for the resulting tax obligations.

Avoiding Tax Complexities

A simple solution is to use stablecoins (Stablecoins) like USDT or USDC. Their prices remain stable and fixed, simplifying tax calculations.

How to Get a Digital Currency Card

Basic Requirements

You must be a customer of a known trading platform or payment service that offers digital currency cards. You will need to complete procedures such as:

• Identity verification (KYC)
• Anti-money laundering verification (AML)
• For credit cards: credit inquiry

Application Steps

1. Log into your platform account
2. Find the section for cards or payments
3. Choose the appropriate card type
4. Fill in the required verification information
5. Select the name format on the card
6. Agree to the terms and conditions
7. Submit your application

Most platforms provide virtual cards immediately after approval, which you can use for online shopping before receiving the physical card.

Supported Countries and Regions

Most digital currency card services primarily operate in European countries, including: European Union countries, Norway, Iceland, and Liechtenstein. The service is gradually expanding to other regions. Check the platform’s official website to confirm availability in your country.

Practical Tips Before Subscribing

Compare Available Options

Each card has different features:

• Cashback rates vary
• Administrative and transaction fees differ
• Additional benefits vary

Calculate Hidden Costs

Check for conversion and exchange fees; there may be fees from intermediaries or banks.

Keep Tax Records

Document all purchases for tax purposes. Keep a record of exchange rates and transaction dates.

Summary

Digital currency cards represent an important step toward integrating digital assets into daily life. They offer a quick and easy way to convert your assets into goods and services without complex, days-long conversion processes. However, be cautious of potential risks, especially price volatility and tax obligations. Use stablecoins when possible to avoid complications, and always ensure you understand the card’s terms before subscribing.
