The document discusses the upcoming requirements for strong customer authentication (SCA) in online payments according to PSD2 regulations taking effect in September 2019. It notes that current authentication methods do not meet needs for simple and secure digital payments. The new SCA rules will require two-factor authentication for most online transactions. Exemptions are provided for small transactions, whitelisting of trusted beneficiaries, and risk-based authentication. The document recommends merchants implement EMV 3-D Secure and Identity Check to help users authenticate transactions in a compliant and convenient manner ahead of the 2019 deadline.
