If you are unable to enter your credit card / debit card, please refer to the following possible reasons:
★The credit card / debit card details are in the wrong format:
1. Credit card number: once the card number is entered correctly, the system will automatically select the card type. Please check that it is correct.
2. Expiry date: the format is MM/YY. Please check the format before submitting.
3. Security code: usually located next to the signature strip on the back of the card (three digits).
4. Cardholder name: please enter the English name shown on the card (e.g. XIA XIAO-BIAN). If there is no English name on your card, please contact your card's customer service.
★The credit card / debit card or bank account has not been activated:
A new credit card / debit card or bank account must be activated or updated with the bank before it can be used.
Please check with your bank that your bank account details and credit card / debit card are valid.
★Network delay / congestion:
If the card-issuing bank's system is busy or the network is congested when you add your details, adding them may fail. Please simply try again later.
