The difference between a USD and HKD card is the currency used for your billing and settlement.
Previously, RedotPay offered both USD and HKD cards depending on your region, device, and other eligibility criteria. As of January 21, 2026, all new cards are issued as USD cards by default.
USD card: Uses USD (US Dollar) for all billing and settlement.
HKD card: Uses HKD (Hong Kong Dollar) for all billing and settlement.
How to check your default currency
You can check your card's default currency in the RedotPay app by following these steps:
Open the app and tap [Card].
2. Tap the eye icon or the card image to flip the card over.
Look at the top-right corner on the back of the card. The currency code shown there (for example, USD or HKD) is your card’s default currency.
