Whether you’re travelling abroad, on an overseas business trip, or shopping on international websites, all you really need is one card to complete overseas payments. However, confusing fee structures and exchange rate calculations often make foreign currency spending feel expensive and unpredictable.
Want to spend more wisely and save on overseas transaction fees? This guide breaks down how overseas card payments work, compares different fee structures and promotions, and helps you manage costs with confidence.
These are card payments made at physical merchants overseas, such as dining at a restaurant in Tokyo or shopping in London. At checkout, you may be given a choice to settle the transaction in local currency or HKD via Dynamic Currency Conversion (DCC).
Transactions made with overseas online merchants, even if you are physically in Hong Kong, are classified as overseas spending. Examples include subscribing to international streaming platforms or shopping on US-based Amazon. These transactions usually incur foreign transaction fees.
Understand Foreign Currency Fees and Exchange Rates
Overseas transaction fees usually consist of two components:
You should also watch out for DCC (Dynamic Currency Conversion). If you choose to pay in HKD overseas, the exchange rate is set by the merchant and is often significantly worse than paying directly in the local currency.
Check Pre-Authorisation and Refund Policies
Hotels and car rental companies often place a pre-authorisation hold on your card to reserve a certain amount.
If a refund is required, processing time, exchange rates and whether transaction fees are refundable vary by bank and card issuer.
Ensure Security and Regional Compatibility
Make sure your card supports:
This ensures your overseas payments go through smoothly and securely.
JCB Overseas Transaction Fees
JCB fees vary by issuing bank. Some banks waive transaction fees for spending in Japan.
For businesses, Wonder Card (JCB) offers a clear fee structure:
Visa Overseas Transaction Fees
Visa cards are widely used in Hong Kong. The standard overseas transaction fee is typically 1.95%.
Mastercard Overseas Transaction Fees
Similar to Visa, Mastercard’s standard overseas transaction fee is also generally 1.95%, making it an industry benchmark.
UnionPay Overseas Transaction Fees
UnionPay cards often waive foreign transaction fees, which is a major advantage.However, some Hong Kong-issued UnionPay cards still charge around 1%–1.2%, so it’s best to confirm with the issuing bank before use.
Most Hong Kong credit cards charge a total overseas transaction fee of around 1.95%.
If a card offers overseas rewards or cashback above 1.95%, it can fully offset the fee—or even generate net savings.
Common Types of Overseas Spending Benefits
Many SME owners or employees initially use personal credit cards to cover company expenses—such as flights, hotels, overseas suppliers or online advertising.
While convenient, this approach creates long-term issues:
Although personal credit cards can be used, they are far from ideal. Businesses benefit more from dedicated corporate payment solutions with backend controls, spending limits and multi-currency support.
For companies, cost control and expense visibility matter more than personal rewards.
Wonder Card is a business card solution designed specifically for overseas corporate spending.
