Geocard

GeoCard is an AI-powered debit card that switches your Bunq account in real time based on location, time, and behavior no taps, no stress, just smart spending.

🌸 Inspiration

GeoCard was born out of a real-life frustration: I was constantly switching Bunq accounts manually and AutoSelect just didn’t get it right. I needed something smarter and understood where I was. So I built it. I wanted a card that could follow my location.

💡 What it does

GeoCard is an AI-powered debit card system that changes your linked Bunq account automatically based on your location, time, and behavior.
The live demo lets you walk around a pixel-art town as BudgetBabe, and watch your card respond in real time — no taps needed.

🛠️ How I built it

I built GeoCard solo — from designing the pixel avatars to building the decision engine. The app uses:

  • A custom location-aware AI layer
  • Live Bunq API integration
  • A frontend town demo with real-time feedback
  • Server-side account switching logic
  • Canva sprites and browser-based animation

🚧 Challenges we ran into

There were quite a few!
Working with the Bunq API was tough — documentation gaps, permissions, and getting card linking to behave correctly took time.
Setting up and tunneling a dev server (thank you lt) was also a headache at first.
And... there was a brief moment where BudgetBabe became self-aware and started setting up multiple bank accounts. One time she even jumpscared me. I debugged with three iced matcha lattes.

✨ Accomplishments that I am proud of

  • I designed all the pixel characters myself
  • My live demo works (I hope it still does 🤞)
  • I successfully connected to the Bunq API and saw real-time account switching
  • I built this entire project solo — from idea to implementation 💪

📚 What I learned

  • How to work with banking APIs securely
  • How to simulate geolocation for demos
  • The power of context-aware AI when combined with good UX

📱 What's next for GeoCard

Next up: mobile integration!
I want GeoCard to run on your actual phone, using live GPS data to auto-switch accounts while you move through real cities.
I'd also love to expand BudgetBabe's town into a full game economy — linking more behaviors to smart financial decisions.
