The six-week rebook is your revenue engine. A win-back notification protects it.

Hair salons operate on a rebook cadence that makes client retention both highly predictable and highly fragile. A client who rebooking every six weeks is worth between $600 and $2,000 per year depending on service mix. A client who doesn't rebook after a single appointment represents an acquisition cost with no return. The gap between these two outcomes is often not satisfaction — it is friction. The client meant to call. They just didn't get around to it.

Digital loyalty cards for hair salons address the rebook friction problem by creating a persistent communication channel that lives in Apple Wallet and Google Wallet. The loyalty card is added at the first visit via QR code at the reception desk. Every subsequent visit earns a stamp or reward credit. The push notification channel reaches the client at 28 days of absence — the exact window when a lapsed rebook is still recoverable before a new salon becomes a new habit.

Stamp cards work well for salons with a defined service cadence — cut and colour clients who visit every six to eight weeks on a predictable schedule. Reward cards work better for salons with a retail component, where product purchases between appointments should also earn toward service rewards. Membership cards suit salons offering recurring service packages — a monthly blow-dry club, a quarterly treatment membership — that create predictable revenue independent of appointment booking.

The Hardcards scanner app runs on any iOS or Android device at the reception desk — no dedicated hardware, no POS integration. Clients scan their wallet pass when they arrive. The visit is logged, the stamp is added, and a push notification confirms the reward progress. The entire interaction takes under three seconds and requires no action from the client beyond presenting their phone.
