The Coupon Flow
Coupon Backend Flow

Inspiration

Our inspiration behind Coufon is to come up with a simple solution on how to create a digital twin on coupons made by the manufacturers and retailers to a branded marketing coupons that consumers readily understand. The concept of digital twins is the reasoning behind the development of Coufon. A digital twin is like a mirror representation of an online marketing campaign, translated into the real-life world.

What it does

We are innovating coupon marketing using branded links in social media, blog articles, offline sales campaigns, and promotions. We want to incorporate the new idea of short, brand-identifiable coupon links that people will understand and memorize (i.e. mystore.available.today)
To convert serialized coupons that are stored in Hedera HTS to become human-readable.

How We Built It

We break down our infrastructure from a monolithic model to microservices model. Each team member was given a task with individual responsibility. We have someone responsible for overall system architecture, a back-end developer, a user-interface designer, and a creative designer.
