ReVo is a web-based coupon sharing and redemption platform designed to reduce the wastage of unused promotional coupons.
With the growth of online payments and digital transactions, users frequently receive promotional coupons and discount codes. However, a coupon may not always be useful to the person who receives it and may eventually expire unused.
ReVo addresses this problem by providing a platform where users can share unused coupons, discover relevant coupons, redeem available offers, and earn reward points for contributing coupons to the platform.
ReVo provides a simple platform for exchanging useful coupons between users.
Users can browse available coupons by category, find offers that are relevant to them, and redeem them. Users can also contribute their own unused coupons to the platform.
To encourage coupon sharing, ReVo includes a points-based reward system. Users earn points when they share coupons, and these points can be used to purchase items through the platform's shop.
- A user receives a coupon that they do not need.
- The user shares the coupon through ReVo.
- The coupon becomes available for other users to discover.
- Another user finds a useful coupon.
- The user redeems the coupon.
- The contributor earns reward points.
- The earned points can be used in the ReVo shop.
This approach helps reduce the number of useful coupons that expire without being used.
Promotional coupons have become increasingly common with the growth of online payments and digital transactions.
However, users may receive coupons that:
- Are not relevant to their needs.
- Cannot be used by the recipient.
- Remain unused until their expiry date.
- Could have been useful to another person.
Existing coupon platforms can also be complicated to navigate or may not provide sufficient incentives for users to contribute coupons.
ReVo aims to provide a simple and user-friendly platform for sharing and redeeming coupons, while introducing a reward mechanism that encourages users to contribute unused coupons.
The main objectives of ReVo are to:
- Reduce the wastage of unused coupons.
- Provide a convenient platform for sharing coupons.
- Help users discover coupons according to their interests.
- Allow users to redeem available coupons.
- Organise coupons into easily accessible categories.
- Encourage coupon sharing through a points-based reward system.
- Allow users to use earned points in the platform's shop.
- Provide administrators with tools to manage coupons and users.
- Provide notifications for newly available coupons.
Customers can:
- Register for an account.
- Log in to their account.
- Browse available coupons.
- Search for relevant coupons.
- Explore coupons by category.
- Share unused coupons.
- Redeem available coupons.
- View previous activities.
- Earn points by sharing coupons.
- Use earned points in the shop.
- Enable notifications for new coupon arrivals.
Users can add coupons by providing information such as:
- Brand
- Category
- Expiry date
- Promotional code
Coupons are organised into categories to make it easier for users to find relevant offers.
The platform also tracks coupon availability. When a coupon is redeemed, its available quantity is reduced.
ReVo includes a points-based reward system.
Users earn points by sharing coupons with the platform.
The accumulated points can then be used to purchase items through the ReVo shop.
This reward mechanism encourages users to contribute coupons instead of allowing unwanted coupons to expire.
Administrators have a separate dashboard through which they can:
- Manage coupons.
- Create and manage coupon information.
- Notify users about new coupon arrivals.
- Access customer information.
- Manage database information.
User passwords are stored in hashed form rather than as plain-text password strings.
ReVo supports separate customer and administrator access.
Customers can register and log in through the customer interface.
Users can explore available coupons without logging in. Authentication is required for actions such as sharing and redeeming coupons.

The administrator experience includes:
- Access the administrator login.
- Open the administrator dashboard.
- Create and manage coupons.
- Manage coupon information.
- Access customer information.
- Manage relevant database information.
- Notify users about new coupon arrivals.
The process for sharing a coupon is:
- The customer logs into their account.
- The customer opens the Add Coupons section.
- The customer enters the brand information.
- The customer selects a coupon category.
- The customer provides the expiry date.
- The customer enters the promotional code.
- The coupon is submitted to the platform.
- The coupon becomes available to other users.
- The contributor receives reward points.
The redemption process works as follows:
- The customer explores the available categories.
- The customer selects a relevant coupon.
- The customer checks the available coupon information.
- The customer redeems the coupon.
- The available coupon quantity is updated.
Users can earn points by contributing coupons to ReVo.
The points can then be used through the shop.
Share coupons → Earn points → Accumulate points → Use points in the shop
The reward system provides an additional incentive for users to share coupons that they do not need.
ReVo was developed as a full-stack web application using the following technologies.
- HTML5: Structure and content of web pages.
- CSS3: Styling and visual presentation.
- JavaScript: Client-side functionality and interactivity.
- Bootstrap: Responsive user interface development.
- jQuery: DOM manipulation, events and AJAX functionality.
- PHP: Server-side application development and processing.
- MySQL: Relational database management and persistent data storage.
- Visual Studio Code
MySQL is used as the relational database management system for the application.
The database supports information associated with areas such as:
- Users
- Coupons
- Coupon categories
- Coupon availability
- Promotional codes
- Expiry information
- User activities
- Reward points
- Shop-related information
The system incorporates basic security considerations including:
- Separate customer and administrator access.
- Authentication for coupon sharing and redemption.
- Password storage in hashed form.
- Database-backed user management.
For a production deployment, additional security measures could include:
- Comprehensive input validation.
- Secure session management.
- Stronger authorisation controls.
- Protection against common web vulnerabilities.
- Secure database configuration.
- Improved access control.
The project was evaluated from three primary feasibility perspectives.
The technologies required for the proposed system are available and provide the capabilities required to develop a database-backed web application.
The selected technologies support the frontend, server-side functionality and database requirements of the system.
The proposed system is designed around commonly available web technologies and infrastructure, making the concept economically feasible for development.
The system focuses on providing a simple interface that allows users to browse, share and redeem coupons while giving administrators dedicated management functionality.
The ReVo concept provides several potential benefits:
- Reduces wastage of unused coupons.
- Helps users discover relevant discounts.
- Encourages users to share unused coupons.
- Provides direct value through discounts.
