Payment Issues
If your card transaction is not approved, first check your entered card information, usage environment, credit limit, or card suspension status. If the problem persists, contacting the customer service number on the back of your card is the most reliable solution.
Possible Causes
■ Incorrect card information
Input errors in card number, expiration date, security code, etc.
■ Credit limit exceeded
When the set credit limit has been reached.
■ Card temporarily suspended
When the card has been temporarily suspended by the card company due to suspected fraudulent use.
■ 3D Secure authentication not registered
When not registered for the personal authentication service for online transactions.
■ International or online payments not permitted
When international use or specific online payments are restricted by the card company.
■ Card or terminal malfunction
Possible malfunction of the card itself or payment terminal failure at physical stores.
Solutions
1
Re-verify and re-enter card information
Confirm that the card number, expiration date, and security code are entered correctly, and delete and re-enter the information if necessary.
2
Check usage environment
Try using a different internet connection, clear browser cache, or verify that the service supports your card brand.
3
Contact your card company
If the problem is not resolved after the above checks, or if the cause cannot be identified, call the inquiry number on the back of your card and explain the situation.
4
Try alternative payment methods
Temporarily trying alternative payment methods may allow you to complete the transaction.
About 3D Secure Authentication
3D Secure authentication is a service to strengthen security during online payments. The main causes and solutions when authentication fails are as follows:
● Incorrect authentication information
Please verify that there are no errors in the password or one-time passcode input.
● Contact your card issuer
If authentication fails, please call your card issuer and report that authentication is not working, along with the transaction amount and date/time. Some card companies may temporarily disable authentication to complete the payment.
● Corporate card restrictions
Some corporate cards may have restrictions on 3D Secure authentication. Please contact your card company to check the setup status and availability.
● Communication environment or device issues
Please use the latest version of your browser in a stable communication environment. In unstable communication environments, errors may occur due to session timeouts.
● Security blocking
Authentication may be blocked by the security settings of your network or device. Please try using a different device or connection.
