Kindly see the reasons below  to find out how you can resolve the issue:   Transaction Limits There is a maximum transaction limit for credit/debit card purchases.    Card errors Card not showing If a new card you have added is not showing, close and reopen your Shopee App. Try troubleshooting if this doesn't work. Incomplete payment If your payment process was incomplete, check with your bank to see if the amount was deducted before making another payment attempt. Alternatively, you can contact Shopee Customer Service or Shopee Cares PH for clarification.   Card not accepted on Shopee Some overseas cards and cards issued by certain banks aren’t accepted on Shopee.
