Banx is a banking app that counts in euros, but also in CO2. Your personal CO2 dashboard calculates the impact of your purchases on the planet. That way, you can adjust whom you shop with and what you buy, while living a more sustainability-aware life.

With Banx Invest you can also invest in funds that promote ecological or social characteristics or which aim to achieve sustainable investing.

Banx is the result of the unique collaboration between Proximus and Belfius. Two 100% Belgian companies that have joined forces for a more sustainable Belgium. Because Banx is all about “slow banking”: in a world that keeps going faster, you can deliberately slow down and think about the impact your transactions are having. So
you can make personal choices that have a positive impact on our society and our planet. Minimum banking for
maximum impact. And you can carry it around in your pocket.

Digital payments are now oh so simple
Banx gives you everything you need to pay or be paid digitally – quickly and effortlessly. Wherever you are. At any time. Securely. If you have a question, our customer service can assist you quickly over the phone, or on social media and chat. Just shake your smartphone.

Do you enjoy a challenge, like we do? Then open an account in the Banx app in less than 5 minutes and take up the challenge of reducing your CO2 footprint. You also earn points in the Banx app that you can redeem for rewards: Like vouchers with one of our local and sustainable partners. Or maybe you’d like to support a nature project in Belgium? Your input, your reward. You decide.

But whatever you opt for, with Banx you’re opting for flexibility and transparency.

Gebruiksvriendelijk en duurzaam

Excellente UX van Belfius gecombineerd met duurzaam verhaal. Aanloggen en ondertekenen met Face-ID superhandig. Graag wel Itsme ondersteuning asap aub.

Connexion Belfius ne fonctionne pas

Impossible de me lier à mon compte Belfius. Erreurs avec itsme et ne fonctionne pas non plus avec le lecteur de carte. Connexion en Néerlandais, impossible de choisir le français. J’ai du faire la demande en tant que non-client Belfius.
