In practice it is most often delivered through 3-D Secure 2, with a one-time code or a biometric confirmation in the banking app.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why It Matters<\/h2>\n\n\n\n<p>In the EEA, a payment that skips a required SCA step is simply declined by the customer&#8217;s bank, so a badly implemented flow costs real revenue. The regulation allows exemptions \u2014 for low-value payments or trusted payees, for example \u2014 and handling them well is what separates a smooth checkout from one that asks for a code every time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Dotcode Applies It<\/h2>\n\n\n\n<p>We implement SCA with step-up authentication and exemption logic from the start, so users are challenged when the risk or the regulation calls for it and not on every transaction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Strong Customer Authentication (SCA) is a PSD2 requirement that electronic payments and account access be verified with at least two of three independent factors: something the user knows, has, or is.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What Is SCA?
