In this article

Cashless societies are taking over. The development and accessibility of electronic payment solutions have made international payment a part of everyday life. According to the 2023 Global Payments Report published by FIS, Hong Kong stood out with only 10% of the market spending in cash in 2022, marking one of the lowest in the Asia Pacific region. The use of electronic payment is projected to surge to 37% by 2026, poised to supplant credit cards as the most used electronic payment method in Hong Kong.

For cross-border businesses, the use of international payment solutions has become a prerequisite for success. Read on to fill the knowledge gap of cross-border payment solutions, and make the best choice for your global business.

Limitations of cross-border payment

In mainland China

Verification and spending limits: Major electronic payment solutions impose a daily spending cap of HK$20,000 and require verification in advance, making it difficult for users to make larger transactions.

Complicated reconciliation: Due to the spending limits, businesses cannot centralize all digital transactions or make B2B payments directly to suppliers using one single platform. Funds end up passing through multiple banks and financial institutions, making monthly reconciliation a headache.


Currency conversion eats up profits: Cross-border payments using overseas banks often involve triple conversion: your customers pay in their local currency, your overseas bank converts to their major currency, and again to your suppliers' preferred currency. The exchange fees and overseas transaction fees involved are paramount and will quickly erode your profits.

Lengthy verification and lower spending limits: Only a few cross-border electronic payment platforms support overseas banks, leading to stricter and more time-consuming verification processes and lower transaction limits. This will be an inevitable hurdle for cross-border business owners.
