What happens when USDT or USDC is used for a card payment? Learn how stablecoin balances may be converted and processed when you make a purchase.

What Happens When You Spend USDT or USDC With a Card?

Can you spend USDT or USDC with a card?

Where supported, USDT or USDC may be used as the source of funds for a card payment.

Both are stablecoins designed to track the value of the US dollar.

However, the merchant does not necessarily receive USDT or USDC directly.

Depending on the card programme, the stablecoin may be converted into the currency required to settle the transaction.

What happens when you make a payment?

A typical transaction may involve several steps:

1. The card is used

The user makes a payment online or at a physical merchant.

2. The transaction amount is authorised

The card system checks whether sufficient eligible funds are available.

3. Stablecoins may be converted

An amount of USDT or USDC may be converted into the required payment currency.

The exchange rate or conversion method depends on the card provider.

4. The payment is processed

The transaction moves through the relevant card payment network.

5. The balance is updated

The corresponding amount is deducted from the user's available balance according to the provider's settlement process.

Does the merchant receive USDT or USDC?

Not necessarily.

With many card-based payment structures, the merchant receives payment through the traditional card network in its supported settlement currency.

The conversion from stablecoins happens separately as part of the card service.

Can the final amount differ from the purchase price?

Potentially.

The final amount deducted may be affected by factors such as:

  • currency conversion
  • foreign exchange rates
  • card or conversion fees
  • pre-authorisation amounts
  • final transaction settlement

The exact process depends on the provider and type of transaction.

Example

A user holds USDC and makes an overseas card purchase.

The purchase is priced in the merchant's local currency.

The relevant amount of USDC may be converted as part of the transaction, while the merchant receives payment through the card network.

Foreign exchange or other applicable fees may also affect the final amount.

In summary

When USDT or USDC is used with a supported card, the stablecoin may serve as the funding source while the actual merchant payment is processed through traditional card infrastructure.

The conversion rate, fees and settlement process depend on the card programme.

Quick Answers

Does the shop receive USDT when I pay with a stablecoin card?

Not necessarily. The merchant may receive payment in its usual settlement currency.

Is USDT automatically converted when I pay?

This depends on the card structure. Some programmes convert eligible stablecoins as part of the transaction.

Can USDC also be used?

Yes, where USDC is supported by the relevant card programme.
