1. ATM Transfer
※ Please note that when using the ATM, select the "bill payment" option and enter the transfer account number provided in the email. After completing the transaction, the financial institution will charge a service fee (usually around 15 NTD). We will not charge any additional fees, so you can use it with confidence.
※ Completing the ordering process does not mean that the transaction is complete or the contract is established. If there are any errors in the transaction conditions, the product is out of stock, the service cannot be provided, or there are other valid reasons, the store reserves the right to cancel the transaction within two business days after your order. This confirmation process also applies when you choose other payment methods. If you leave the page after entering the Green World Technology payment page without obtaining the virtual account payment information, the system will update your order to "failed due to exceeding the payment deadline" after approximately one hour.
2. Credit Card Payment
(Full Payment/Installment Payment):
If you choose to pay by credit card during checkout, please make sure to fill in your details accurately for verification with the bank.
After the identity and information verification with Rakuten Market and the credit card center, if everything is in order, the store will proceed with the billing and shipping process.
If your credit card details do not match with the credit card center, the store will contact you to confirm the information again.
※ To ensure the security of online transactions, you agree that the company may verify the authenticity of the information with the issuing bank and cardholder. Please be reminded that if fraudulent use of someone else's credit card or other personal information is detected, the case will be referred to legal authorities.
※ To protect the rights of cardholders, if the information you provided does not match with the issuing institution, the store will proactively contact you to confirm the details and re-verify with the issuing institution. If you refuse to provide detailed information or if there is still incorrect information after confirmation, the store reserves the right to cancel the order.
※ The credit card authorization only confirms the validity of the card and the authorized transaction amount; it does not mean your payment has been completed. Once the store accepts your transaction, it will request payment from the issuing bank. Only when the store requests payment will the transaction appear on your credit card statement, and your payment process will be considered complete.
※ The company currently accepts only the following three types of credit cards: VISA, MasterCard, and JCB. Cards such as American Express are not accepted at this time.
※ If the transaction goes through a 3D verification process, it means that after submitting the order, you will be redirected to the issuing bank's 3D verification page. The page is typically valid for 10 minutes. If the customer does not enter the verification code within the time limit, the page will expire, and the order will be updated to "Payment time exceeded" one hour later. If the customer still wishes to proceed with the order, a new order must be placed.
After clicking the "Submit Order" button, the screen will automatically redirect to Greenworld's payment page. The customer must enter the correct credit card information and phone number on this page. After submitting, the customer will be redirected to the issuing bank's 3D verification page (if 3D verification is enabled) or the Greenworld verification page (if 3D verification is not enabled). The customer must enter the correct verification code to complete the payment process.
If the customer exits or closes the payment page during the process, for security reasons, the same page cannot be accessed again for payment. The customer will need to place a new order (payment deadline: please complete the payment process within 10 minutes after entering the Greenworld payment page).
*Payment Deadline: Please complete the payment process within 10 minutes after entering the Greenworld payment page.
After clicking the "Submit Order" button, the screen will automatically redirect to Greenworld's page. The customer must click the "Get ATM Account" button on the page to obtain a virtual account. Then, the customer should use an ATM, mobile banking app, or online banking to transfer or pay using the virtual account number. Please note that some physical ATMs only support the "Pay" function; for more details, refer to Greenworld's official website.
### Reminder! After the order is placed, payment must be completed within 3 days for the order to be successful. Otherwise, the system will automatically cancel the order.
For example, please make the payment before the final payment deadline of 23:59. If you miss the deadline, please do not proceed with the payment. ###
1. Why did my credit card payment fail?
If your credit card has not exceeded its limit, please return to the store and try making the purchase again.
Reminder! Please double-check that the credit card number, name, expiration date, and the last 3 digits on the back of the card are entered correctly. If you still receive an authorization failure notification, the issue may be due to an internal system error at the issuing bank. Please contact your credit card issuer for further assistance.
Common Error Codes: 10100248, 10100058
To ensure information security and prevent malicious attempts using incorrect information for testing, the error codes and messages cannot be fully detailed.
If you encounter error codes 10100248 or 10100058, it means the credit card used by the consumer was declined by the bank. The reason for the decline could be due to incorrect information, insufficient credit limit, or other reasons. For the specific cause, the consumer should contact their card issuer.
Q: What should be done if the consumer claims to have received a successful payment notification or confirms with the bank that the transaction was authorized, but the backend of ECPay shows an authorization failure?
A: This situation means ECPay did not successfully request authorization from the bank, indicating the payment attempt failed. Please follow these steps to verify:
Go to Vendor Management Backend > Credit Card > Transaction Details Query.
If the transaction is shown with a "gray background," it means the payment failed.
Q: What should I do if the consumer insists they received a notification and are sure they have been charged?
A: You can ask the consumer to check their "billing statement" from the bank for confirmation. If it shows a charge, kindly request the details and upload them via the "Customer Service Online Report" for further assistance from our team.
