Inside the WHAMP build: turning WhatsApp into a loyalty programme

Inside the WHAMP build: turning WhatsApp into a loyalty programme WHAMP is our take on what a loyalty programme looks like when you stop asking customers to download anything. A shopper scans a QR sticker on the counter, a WhatsApp chat opens, they tap send — and the stamp lands in their card. No app store, no password reset email three weeks later, no abandoned icon on a home screen. The whole loop lives inside the messenger people are already using forty times a day.
