TongaMarket.com  uses DOKU & BANK OF THE SOUTH PACIFIC advanced online payment gateway system that incorporates 3D security measures along with multi-factor authentication (MFA) for verifying transactions. This system combines the use of a verification code sent through email or text message with 3D secure technology to ensure a high level of security for online payments. Here’s an outline of how such a system might work:

Concept: Enhanced 3D Secure Online Payment Gateway

Key Components:

1. 3D Secure Technology: This is a security protocol designed to be an additional layer of security for online credit and debit card transactions. It’s often referred to as “Verified by Visa,” “Mastercard SecureCode,” or “American Express SafeKey.”

2. Verification Code via Email or Text: As part of the authentication process, a unique verification code is sent to the customer’s registered email or mobile phone.

3. Integration with Bank’s App: In some instances, the verification might involve the bank’s app, where the user confirms the transaction.

Transaction Flow:

1. Initiation of Payment: The customer enters their card details on the merchant’s payment page.

2. 3D Secure Authentication: The payment gateway redirects to the 3D Secure interface, where the customer’s bank verifies the card details and assesses the risk level of the transaction.

3. Verification Code Sent: Depending on the risk assessment and the bank’s policy, a verification code is sent to the customer’s email or mobile phone, or the customer is prompted to authenticate the transaction in their bank’s app.

4. Customer Verification: The customer enters the received code or approves the transaction in the bank’s app. This step verifies that the actual cardholder is authorizing the transaction.

5. Transaction Completion: Once the verification is successful, the transaction is processed. If the verification fails, the transaction is declined to prevent potential fraud.

Advantages:

1. Enhanced Security: Combining 3D Secure technology with a verification code significantly reduces the risk of fraudulent transactions.

2. User Verification: Directly involving the customer in the authentication process helps in verifying the rightful owner of the card.

3. Compliance: Meets regulatory requirements for strong customer authentication, especially under regulations like the EU’s PSD2.

4. Customer Trust: Increases customer confidence in the security of online transactions.

Considerations:

• User Experience: Ensure that the added security steps do not overly complicate the transaction process, potentially leading to abandoned carts.

• Accessibility: Consider the accessibility of receiving verification codes for all customers, including those with limited access to mobile devices or email.

• Privacy and Data Security: Safeguard the customer’s personal information, including their phone numbers and email addresses.

By integrating 3D Secure technology with a multi-factor authentication system that utilizes verification codes sent to a customer’s email or phone, you can create a robust and secure online payment gateway. This approach addresses the growing concerns over online transaction security while maintaining a balance with user convenience.
