Strong Customer Authentication Decision Tree


Issued 06/2019



  • *If your terminal or ecommerce solution is provided by us, we’ll ensure your transactions are SCA compliant and flagged correctly.

    If you own or rent your terminal from another source or use a third party provider for your ecommerce service, further information on PSD2, SCA, the transaction types and what’s required to be SCA compliant are in our PSD2 and Strong Customer Authentication Technical Implementation Guide.

    The same guide also explains which transactions can be exempted from SCA and how you should correctly flag them.
