What is 3D Secure and why is this solution considered an important “shield” to help prevent fraud in transactions? Let’s find out in this article.

3D Secure is an indispensable security technology in today's digital age, helping businesses feel secure when making online payment transactions. So, what is 3D Secure?? Let's join SeABank to learn more about the operating mechanism, benefits, and importance of 3D Secure in the current booming online payment context.

What is 3D Secure?

3D Secure is a modern security technology that enhances the safety of cardholders when making online payments. This mechanism requires customers to verify their identity with an OTP (One Time Password) code - a one-time password sent by the banking system to their phone number via SMS during the transaction. The OTP code is usually only valid for 30 seconds to 2 minutes, ensuring that only the cardholder can complete the payment.

Benefits of 3D Secure in online payments

Currently, 3D Secure is considered a solid security shield, playing an important role in authenticating cardholders and protecting the safety of each transaction. Businesses can refer to some of the outstanding benefits of 3D Secure in online payments below to better understand the security value that this technology brings:

Enhanced authentication, ensuring cardholder accuracy

Instead of relying solely on card information, 3D Secure adds a layer of multi-factor authentication by sending a one-time password (OTP) to the cardholder’s phone number or email. This process ensures that each transaction can only be completed by the cardholder, eliminating the possibility of fraudsters exploiting stolen information.

Popular OTP forms that businesses can refer to today are:

  • SMS OTP: OTP code is sent via SMS, valid for a maximum of 5 minutes, and includes information for customers to identify the purpose of use.
  • Email OTP: OTP code is sent via email, valid for up to 5 minute,s and shows the purpose of use to the customer.
  • Voice OTP: OTP code is sent via voice call, valid for up to 3 minute,s and accompanied by a clear notification to the customer.
  • Soft OTP: OTP code is generated from the application installed on the mobile device (separate application or integrated Mobile Banking), valid for a maximum of 2 minutes.
  • Token OTP: OTP code generated from a specialized device, can be random or combined with a transaction code, valid for a maximum of 2 minutes.

Prevent fraud remotely, protect business assets

Even if the card data (card number, expiry date, CVV code) is accidentally exposed, 3D Secure is still the last barrier to prevent unauthorized transactions. Thanks to the OTP code requirement, all fraudulent payment activities are disabled, helping businesses protect assets from unwanted risks and losses.

Using 3D Secure will help prevent fraudulent transactions.

In addition, businesses also need to note some important points to use OTP codes safely:

  • Do not share OTP with anyone: Whether in the form of a call, text message, email, or social media - banks and financial institutions never ask you for an OTP.
  • Only enter OTP on official channels: Only enter OTP on the bank/business's official website or application; avoid clicking on strange links.
  • Check the notification content with OTP: Make sure the OTP is sent for the correct transaction you are making.
  • For devices receiving and using OTP codes: You should regularly change your password, set a strong password for your phone, and avoid using public wifi or strange devices to make transactions.

Minimize complaints, optimize business processes

For businesses, applying 3D Secure not only helps reduce complaints and chargeback requests but also ensures that all transactions are authenticated. This authentication mechanism helps banks and card accepting units clearly identify customers as the ones making the transactions, thereby limiting fraud, handling disputes quickly, and maintaining stable business operations.
