eWallet System

This is repository contains web softwares for a eWallet system.

System aims to perform operations like a real e-wallet applications like PayTM, i.e, able to transfer funds from one user to another, deposit and withdraw funds from external banks, and track the movement of funds.

Here, I tried to spoof the external bank softwares, i.e, they mimicks like a bank software, but arent, they just play along to complete the flow of the application.
