Why is my credit card not working?*

Updated October 20, 2026

If your credit card isn't working, it could be for a few reasons: It hasn't been activated yet The wrong card details were entered for the transaction The transaction was blocked Here's how to fix it: 1. Make sure your card is activated and not temporarily frozen. 2. Next, check your Activity feed online or in the Novo app. If you see a declined transaction, select it to see exactly what happened. 3. If no declined transaction is showing, double-check that your card details and billing address were entered correctly online. If you try these steps and still need help, reach out to Support online or in the app.
