The problem
Pepsi needed a Tết promotion buyers could join in seconds — no app install, no long form.
What we built
A Zalo Mini App with one-tap login, a cap-code scanner, a lucky wheel that paces prizes against a daily budget, and a prize wallet redeemable in store.
Anti-fraud locks used codes within milliseconds and flags devices with abnormal scan patterns.
Highlights
- One-tap loginPhone number via Zalo, no OTP needed.
- Budget-paced prizesWin rates adjust hour by hour.
- In-store redemptionSingle-use QR for every prize.
