Payment Transaction System Using QR Codes

Abstract

The purpose of this project is to create a payment transaction system that generates QR codes on a mobile application and website with a specific amount of money decided by the receiver and can be adjusted by the payer. Nowadays people do not carry cash around with them, but they do carry their phones. This project is mainly directed to two different groups of users. The first group is people without a steady income source who live based on donations and might not have a phone to access other methods of payment. The second group is people with jobs where a big portion of what they make is based on tips, such as waiters, doormen, or valet attendants. Our group, Team 18080, proceeded to create the app, starting with prototyping and research, and then actual coding, leading to a fully functioning app on iOS, Android, and on all web browsers. The app interface was created with React Native with an Azure Database securely storing all information. Payments are processed with the Stripe Payment Processor. The website was created with HTML, CSS, and JavaScript.
