What Is 3D Secure

3D secure, also known as 3DS, stands for 3-Domain Server. This is because each transaction authentication involves 3 parties. These three parties are; the acquirer domain, the issuer domain, and the interoperability domain.

The acquirer domain is the seller’s bank that will be accepting the card payment. On the other hand, the issuer domain is the organization that issued the credit card being used in the transaction. Then the interoperability domain is the payment system that links the acquirer domain to the issuer domain.

How 3DS Works

Let’s say you are an online seller who accepts card payments with 3DS enabled on your website. Now, here comes a customer with a 3DS enabled card. Below is what the payment procedure will be.

  1. The payment form will first prompt the buyer to enter their card information.
  2. The directory server is then contacted to verify that the card is registered for 3D Secure and sends back a message to confirm.
  3. The buyer is then redirected to a 3D secure page served by the card provider, e.g. the bank that issued the card.
  4. Next, the buyer has to enter a password, a one-time PIN, or a one-time authentication code. This will be sent to them via a confirmed mobile number or email address.
  5. If the authentification is successful, the buyer is redirected back to the seller’s website to confirm payment.
  6. Finally, the buyer will receive confirmation of a successful payment.

The main benefit of 3D Secure is that it shields both the seller and buyer from the ever-growing threat of fraud in online payments.
