Marks and Spencer Case Study on SCA Implementation

This case study details the collaboration between Marks and Spencer (M&S) and Accertify in response to the Strong Customer Authentication (SCA) regulations introduced on March 14, 2022. The document outlines how M&S implemented a solution that provides a frictionless customer journey for 99.98% of its customers while achieving a 55% reduction in fraud rates. The partnership aimed to address the challenges posed by SCA regulations, which require card issuers to decline non-compliant transactions, potentially leading to increased cart abandonment. The case study explains the migration of M&S's fraud prevention measures to a pre-authentication environment, utilizing Accertify’s SCA optimization solution to enhance the customer experience without compromising fraud management. The implementation phase included a silent mode trial, demonstrating the effectiveness of exemption management in providing a seamless payment experience. The results indicate significant improvements in chargeback fraud rates and overall fraud management efficiency.
