Challenge
Plastic loyalty cards stayed in kitchen drawers. Customers often came back later than planned for regular products, and over-the-counter attach rates were low because there was no timely, private reminder. The group needed a GDPR-friendly channel that was not another app.
Strategy
Customers received a Wallet Pass at the counter. The pass stored only loyalty points and a refill date the customer chose to save — not medical records. A push three days before the date, plus points for related OTC products, brought people back without printing another card.
