You completed a payment inside the app.
The amount looked normal during checkout.
But when you checked the receipt or billing history, the currency was different.
Instead of KRW, it showed USD, EUR, or another foreign currency.
This often causes confusion and concern.
Why App Payments Sometimes Appear in Foreign Currency
- The app store processes payments through an overseas billing entity
- The service provider is registered outside your country
- Your payment was authorized in foreign currency first
- Currency conversion occurs after authorization
Many digital services operate global billing systems.
The transaction may not be processed domestically.
Authorization vs Settlement Currency
- Authorization currency = initial approval currency
- Settlement currency = final billed currency
You may see foreign currency at approval.
Later, your card statement converts it to local currency.
When the Final Charged Amount Changes
- Exchange rate fluctuations
- Card network conversion fees
- Issuer bank processing fees
This can make the billed amount slightly higher or lower.
How to Verify the Actual Charged Currency
- Check your card statement
- Review final settlement records
- Compare authorization vs posted transaction
Foreign currency display does not always mean foreign overcharge.
