Card Recommendation

Card Manager

Inspiration

Our inspiration for this project was to empower individuals, enabling them to make well-informed financial choices effortlessly. Our goal was to eliminate the need for extensive hours of sifting through intricate credit card terms and conditions, making financial decision-making accessible to everyone.

What it does

The application stores information about the various credit cards used by the client. When a client wishes to make a purchase, they can simply open the app. It will then utilize location data to automatically identify the type of store they are in and recommend the most suitable credit card for that specific transaction, optimizing their benefits and rewards.

How we built it

The framework of the mobile application is React Native. We used Python for information processing/retrieval to and from Google Places API as well as OpenAI API. We also used JavaScript for app functionality.

Challenges we ran into

We had an issue because when we retrieved users' location data, we could initially only map their location to an address that could have multiple stores in its area depending on the density of the stores (in plazas/malls, etc). We solved this problem by making the program get the closest store within a 100m radius of the retrieved address.

Accomplishments that we're proud of

Building a React-Native app with no prior experience with the framework. Working around hurdles within our techstack and maintaining the original project idea. Utilizing and learning how to use new API's (OpenAI, Google-Places).

What we learned

How to work efficiently in a team. By finding what needs to be done and delegating tasks among the group.

What's next for Blitz

Future additions for Blitz is to add a database of credit cards and their rewards so the user can search for what card they have and add it to their account. Index our own map data to make it more accurate for our use case. Track user spending to recommend new cards. Create a physical card that stores all the other credit card data to automatically choose the card for you. A Chrome extension for online checkout.
