Inspiration

The inspiration came from coming to Yale this weekend. Being outside of the US, many of our fellow hackers were warning each other of conversion rates, bank fees and tax when spending in another country.

What it does

GeoExchange takes your location using the Pitney Bowes API in order to find out what the tax is in the area, after selecting your bank, it calculates the bank fees, exchange rate as well as tax for a purchase you will be making.

How I built it

GeoExchange is build with react-native using both the Pitney Bowes API for location as well as Fixer.io for current exchange rates.

Challenges I ran into

Working with the Pitney Bowes API was challenging when trying to generate an authentication token.

Accomplishments that I'm proud of

I've never used react-native before and to see that I was able to build a functioning app in a weekend with technology I have never used makes me proud!

What I learned

I learned the basics of react-native and how to make API calls and work with JSON data.

What's next for GeoExchange

I will refine the app, ideally add the functionality of being able to use the camera to get the price of the product from the tag.
