Payment Cards: Strong Customer Authentication

26 June 2025

    There are some new regulations regarding Strong Customer Authentication (SCA): https://www.fca.org.uk/consumers/strong-customer-authentication

    Banks in the UK have until September 2021 to implement this:

    Strong Customer Authentication (SCA) is a new European regulatory requirement to reduce fraud and make online payments more secure. To accept payments and meet SCA requirements, we need to build additional authentication into our checkout flow.

    SCA requires authentication to use at least two of the following three elements:

    • SOMETHING THE CUSTOMER KNOWS (e.g., password or PIN)
    • SOMETHING THE CUSTOMER HAS (e.g., phone or hardware token)
    • SOMETHING THE CUSTOMER IS (e.g., fingerprint or face recognition)

    Therefore please add your card again to our system which will trigger the SCA compliance.

    Login to www.netistrar.com

    Click Menu > My Dashboard > My Account

    Click Manage Payment Methods

    Click Add Payment Method

    Add the card again

    At that point Stripe will check the card again for SCA

    At the point you add your card to the dashboard, if the bank requires second authentication a pop up will appear redirecting you to your bank to preform 2FA with your bank (this is all handled by Stripe). If nothing pops up at this point then, you should be fine for future payments.
