Introduction to PSD2 and Strong Customer Authentication (SCA)

The Second Payment Services Directive (PSD2) is a revision and a replacement of the first Payment Services Directive, regulating all payment services across the European Economic Area (EEA).

PSD2 introduces Strong Customer Authentication (SCA), which will apply to customer-initiated online card payments where the bank of the card holder and the payment provider of the business are both located in the EEA. The requirements also apply to UK organisations on departure from the EU.

SCA ascertains a customer's identity and relies on the presence of two factors for authentication of a transaction. The most commonly used mechanism for card payments is 3DSecure. Customers know 3DSecure under the name of “Verified by Visa” or “Mastercard Identity Check”. As soon as SCA is mandatory, transactions that are not authenticated might be declined.

The impact of PSD2

All online businesses accepting credit card payments will need to ensure their checkouts can perform SCA challenges so that card-issuing banks can process payments. If the required level of authentication is not provided, transactions will be declined.

For many consumers, SCA will be a new experience. As an example, card-issuing banks who use authentication services offered through Visa or MasterCard will display a challenge screen similar to the one below when customers place orders using their credit card.

If you have an online business, it will be important for you to help educate your customers about SCA and what they should do when they see a SCA challenge to avoid increased cart abandonment.

Timing

The directive will become mandatory on 14 September 2019. To make sure you are prepared well ahead of the deadline, we recommend that you complete these changes by 30 June 2019.

Custom Integrations

Ecommerce Solutions

Do you have a custom integration with Amazon Pay?
You will need to update your Amazon Pay solution by applying code changes as described in the Amazon Pay SCA Upgrade Integration Guide. We have also updated our Software Development Kits (SDKs) to support your developers with these changes.

Have you integrated Amazon Pay with your off-the-shelf ecommerce solution?
We are working with our ecommerce solution and plug-in partners to update these ready-made integration options. Once the update is available, you will need to upgrade your integration by installing the latest plug-in. If you are running a hosted, all-in-one e-commerce solution with Amazon Pay pre-installed, your provider will take care of all necessary changes and you will be automatically updated.
