QR-code based E-wallet System using Android platform

Abstract

Currently, in order to make payment or purchase an item, the INTI community needs to pay with
physical cash. Since they use physical cash, it means they are required to carry their wallet/purses
around, and there is a chance that they may lose it, thus, money is lost/stolen. Furthermore, they
need to make frequent trips to Automated Teller Machines (ATM). The E-wallet can provide a
safer platform to make payments and purchase items, thus eliminating the need to carry cash
around. E-wallet system is a kind of electronic card which is utilized for exchanges made online
through a PC or a cell phone. Its utility is same as a credit card. An E-wallet should be connected
with the person's bank account to make payments. This paper aims to study about E-wallet system
and how it can be implemented into INTI community. The objectives of this project was to study
about the current methods of making payments in INTI while investigating how E-wallet system
can be used to enhance payment experience and safety for INTI community. After that, to design
and implement a mobile application which is QR-code based and lastly, to conduct testing for the
proposed system to ensure the accuracy. For this project, the author primarily used Android Studio
as the software to develop the system and Firebase Real-Time database to store and retrieve users’
information. The project has demonstrated the basic needs of an E-wallet System and showed that
it is possible to be implemented in INTI.
