Background
An airport campaign has a hard time window: travellers claim coupons within a few days and redemption happens at the counter, where a queue cannot wait. Claiming has to be fast, redemption faster, and the merchant-side flow simple enough to need no training.
What we did
- Built an Alipay mini-program to run the coupon claiming flow
- Gave merchants an in-program redemption entry that works by scanning, with no extra hardware
- Added campaign configuration and coupon stock management, adjustable during the campaign
- Kept each coupon in a single state between claim and redemption so it cannot be redeemed twice
