Available upon request:

• Usage + Testing demo
• Repository for implementation of C Project: ARM11 emulator and assembler

Project Summary:
Designed to eliminate the need of paper receipts.
Our program enables merchants to take and manipulate orders from customers; after an order is paid, the receipt can be issued via email to the customer.

Usage

Notes: Email login as the sender currently only works for limited email accounts due to security reasons

1. Run make merchant
2. ./merchant without any arguments runs the program in interactive mode
   1. Login - merchant prompted for an ID
   • New ID: Prompt for registration with password (hashed and stored with ID in merchantID.txt)
   • Existing ID: Prompt for password which will be checked against stored hash
   2. Setting sender email
   • Merchant will be prompted for an email address and password from where receipts are sent to customers
   • Authentication currently only works for gmail accounts which allow access from less secure apps
   3. Menu loaded, merchant actions:
   • Each merchant has their own folder (id as folder name, stored in Merchants folder) which stores a record of receipts and the merchant's menu of items to sell (currently only supports addition by manually moving a menu text file into the folder)
   • After successful login, the menu will be loaded and the merchant can select actions to be carried out by inputting the action's corresponding number as follows :
     [0] Quit program
     [1] Take new order
     [2] Edit order
     [3] Cancel order
     [4] Pay order + Send receipt
