Point a camera at it
One code per app, and each one works on both iPhone and Android — it sends the phone that scanned it to the right store on its own.
For customers
Book a salon
Offers near you, prices you can compare, and a slot held the moment you pick it.
For salon owners
Run your salon
Appointments, staff, leave, billing and payouts — free to use, on the phone in your pocket.
Printing these on a card for the counter works too — the codes point at this site rather than at a store, so they keep working even if a listing moves.
