    paper ClubDia - Digitization of the coupon and benefits system

    ClubDia — Loyalty Program Digitalization

    UX / UI Design · Web & App · 2023

    01 — Context & Problem

    ClubDia is a loyalty program from a major supermarket chain. The entire coupon and benefits system existed only in physical format: printed cards, paper coupons, and manual codes at checkout.
    The challenge: bring the full experience to the digital environment — web and app — without losing clarity for the user and reducing friction at the moment of purchase.

    100% physical process before this project3 channels to unify: web, app & in-store
    4 key features to designUsers with digital loyalty cards

    02 — Research & Discovery

    We combined interviews with frequent users, usage data from the physical system, and stakeholder feedback to identify the biggest pain points.
    Key findings:

    • Users didn’t know which coupons they had available until they reached checkout
    • The redemption process was confusing and depended on the cashier
    • The physical card was frequently lost or forgotten
    • Data showed a low usage rate of available coupons

    03 — Definition & Strategy

    From the research we defined 4 clear design goals:

    1. Visibility — All coupons available in one place
    2. Frictionless redemption — Automatic application, no manual code needed
    3. Digital card — A functional replacement for the physical card
    4. Multichannel clarity — Step-by-step instructions per channel: web, in-store, app

    04 — Final UI
