You paid in euros, zlotys or baht, yet the history shows a single currency. This article explains where that number comes from, when the rate is set, and how to avoid a worse one.

A card is tied to a base currency, and every operation is recorded in it. If you pay for a coffee in a foreign currency, the history still shows the amount converted into the base currency. This keeps the record consistent: your balance is held in one currency, so each spend has to be expressed in it. The amount on the receipt and the amount in the history can therefore differ, and that is expected.
The conversion is done by the card network, not by the shop and not by you. It happens at the time of the transaction, so the rate applied is the one in force at that moment. This is why you cannot know the exact base-currency amount in advance from a price tag alone. It also means the figure in your history is the result of that single conversion, not something recalculated later.
DCC stands for dynamic currency conversion. It is the offer, at a terminal or on a checkout page abroad, to pay in your home currency instead of the local one. It looks convenient because you see a familiar number. But accepting it changes which rate applies to the payment, and usually for the worse. The price you agreed to at the till may then not be the cheapest way to pay.
The difference is in who sets the conversion and how visible the result is. The table below sets the two choices side by side. When in doubt, the local currency is generally the safer pick, because it leaves the conversion to the card network.
| Choice | Who converts | Rate outcome | When to use |
|---|---|---|---|
| Pay in local currency | Card network, at the time of the transaction | Network rate applies | Default choice abroad |
| Accept home-currency pricing (DCC) | Set through the DCC offer | A different rate applies, usually worse | Only if you have checked the rate |
| Check afterwards in history | Already done | Shows the converted amount | To confirm what was deducted |
Open the transaction history and find the operation. Each one is listed, so you can compare the amount with your receipt and see what was actually deducted. Keep in mind that the history shows the converted figure, so a foreign-currency price will not match it digit for digit. If the amount looks higher than you expected, check first whether you accepted a home-currency offer at the terminal.
Nexus Pay is a crypto wallet with a Visa card, opened inside Telegram, and it is not a bank. Purchases on the card cost 0%, and moving money from the wallet balance to the card costs 0.1%: 1000 USDT becomes $999.00 on the card. Those fees are separate from the rate at which the card network converts a foreign payment, so read them as different lines. The card spends only the available balance, and you can freeze it in one tap if something in the history looks wrong.
In Telegram, in a minute, with no paperwork.
