SCA and the Liability Shift

Published 29/09/2020

SCA and the Liability Shift

Traditionally, merchants were liable for e-Commerce chargebacks. However, with the new PSD2 SCA (Strong Customer Authentication) regulation, the liability for fraudulent chargebacks will now shift to the card issuer in the majority of cases. This liability shift to the issuer will most commonly occur when the payment has been successfully authenticated through 3D Secure protocols and the card involved is a Mastercard, Maestro, American Express, JCB, Visa, Diners Club International or UnionPay card.

If a merchant has initiated 3D Secure to process online payments, a large number of payments will be protected from fraud liability throughout Europe as long as the issuer has authorised the transaction. This will still apply even if the issuer is unable to support SCA.

However, some merchant banks also require additional confirmation on AVS/CV2 verification before they will consider a liability shift. This will inevitably be down to the agreement that the merchant has with their bank for liability shift cover.

Effective on 17 October 2021, VISA have announced that fraud liability protection for merchants submitting transactions using the older, Version 1 of 3D Secure will no longer apply. This means that all merchants will eventually need to upgrade to 3D Secure V2 in order to take advantage of the liability shift from 2021, so that they are not left vulnerable to chargebacks and the associated costs.

Benefits of the SCA Liability Shift for Merchants

The SCA liability shift can greatly benefit merchants by reducing chargebacks and the costs associated with fraud, shifting the liability to the card issuer in most cases. Unless 3D Secure authentication is performed, merchants are generally liable for fraudulent activity.

By upgrading to 3D Secure Version 2, merchants can reduce their liability towards fraudulent transactions, therefore reducing risk and increasing profitability. Furthermore, the technology upgrade encourages a more positive user experience for customers through frictionless challenges and improved risk-based decisions using cardholder data which in return can lead to the increase of cardholder confidence.

Switching to 3D Secure Version 2 can result in an estimated 5% to 10% of all authentications resulting in the cardholder being redirected to their issuer’s 3D Secure page to complete the two-factor authentication process. Due to this, most authentication requests will have an estimated authorisation rate of 90%, with the liability for unauthorised transactions passing to the card issuer.
