Walk-in business is genuinely good for a nail salon — it's revenue that didn't need marketing spend to show up. The problem isn't the walk-in itself, it's the interruption: someone walks in mid-appointment, and now a technician who's elbow-deep in a gel application has to stop, wipe their hands, walk to the front, figure out what the walk-in wants, explain the wait, and get back to the client they were already with — who's now sitting there watching this happen.
Multiply that by however many walk-ins come through in a day, and it's a real tax on focus and service quality, even though the walk-ins themselves are welcome business.
What a kiosk actually removes from that sequence
A self-service check-in kiosk doesn't eliminate the interruption of a new person arriving — someone still walks through the door. What it eliminates is the part where a technician has to personally stop and manage that arrival. The walk-in taps through a service selection and technician preference (or "any available") on a tablet at the front, and they're added to a live waitlist automatically. No one has to leave a client's chair to make that happen.
Booked clients benefit from this too
It's not just a walk-in tool. A client who already has an appointment can check themselves in the same way — enter their name or phone number, confirm arrival — instead of needing someone at the front desk to notice they've arrived and update anything manually. For a solo technician working without a dedicated receptionist, this matters just as much as it does for a full team.
The part that actually protects the wait experience
A waitlist only works if it's visible and accurate. When someone checks in — whether walk-in or booked — Certxa's kiosk prints a ticket at the front desk and updates the live waitlist instantly, so there's no ambiguity about who's next. That visibility is what keeps a walk-in from feeling ignored while they wait, without anyone needing to personally manage the queue in their head.
A quieter benefit: it becomes a review moment too
Once a service wraps up, the same system that handled check-in can trigger a review request at exactly the right moment — right after a good experience, while it's fresh. That's a separate piece (covered here), but it's worth knowing the kiosk isn't just a queue tool — it's also the first touchpoint in a chain that ends with a Google review, if it's set up to be.
What it takes to set up
It runs on any iPad or Android tablet — no proprietary hardware, no special mounting. Open Certxa in kiosk mode, lock the screen to the check-in flow, and place it wherever makes sense at the front. For salons that don't currently have a dedicated front-desk person, this is often the single change that does the most to reduce mid-service interruptions.
