NFR - Near Field Receipts

Inspiration

While attempting to brainstorm for a food planning app, we realized that we would need the receipts to track pantry data. We then realized that receipts were still a clunky, outdated problem, and our group proposed that we digitize them as a way to increase user convenience, and reduce the waste from receipts. Receipt waste sums up to 1.5 billion lbs of paper waste a year, which stems from 2 million trees, as well 1 billion gallons of water waste. We intended to reduce this by creating an easy method by which consumers could receive and store receipts of any kind.

What it does

The application allows for easy to use interface between the user and the business. Our theoretical concept would take the full receipt of a store and digital uploads it to a server that allows for the user to see their full receipt.

How we built it

Android Studio, Javascript, XML, Marvelapp.

Challenges we ran into

Understanding how to transmit data over android beam and through NFC tags. Additionally learning Android developer API and the NFC API

Accomplishments that we're proud of

Researching receipt paper waste and NFC tag uses. We have a working demo of a mock receipt to send through NFC

What we learned

Android Development, NFC interaction

What's next for NFR - Near Field Receipts

Using a register to transmit the data through its own NFC tag rather than having a phone emulate this process. Create a secure server to store receipt data for individual users.
