Understanding SCA: More Than Just a “Bouncer”

The EU’s PSD2 mandates that merchants utilize SCA methods at checkout adding a layer of verification beyond just the customer’s card details.

This means relying on Two-Factor Authentication (2FA) where customers are asked to prove their identity using two out of three factors:

Knowledge: Something only the customer knows like a password or PIN.
Possession: Something the customer has like a physical token or a smartphone with a mobile app.
Inherence: Something the customer is like their fingerprint or facial recognition.

So instead of just entering their card details customers might be prompted to enter a one-time password (OTP) sent to their phone or use their fingerprint sensor to authenticate.

SCA Impact on WordPress Users: A Global Concern

Now you might think “I’m not in the EU so this doesn’t affect me.” But think again! If you’re selling online you’re likely to have customers from all over the globe including the EEA.

This means you need to be SCA-compliant to avoid customer frustration and potentially lost sales.

For example imagine a customer from Germany trying to buy a product on your WordPress store.

If your checkout system isn’t SCA-ready they might be blocked from completing the purchase.

You’ll be left scratching your head wondering why they’re abandoning their cart.

Navigating SCA Compliance with WordPress

The good news is there are ways to make your WordPress website SCA-compliant.

Here’s what you need to know:

1. Payment Gateways: Your First Line of Defense

The first step is to ensure your chosen payment gateway supports SCA.
