QR codes for salons and barbers
For a salon the booking code is the one that matters, and it belongs in the window where it can be scanned when you are closed. Rebooking codes on the mirror and on receipts capture the customer while they are still in the chair.
The window code works after hours
A salon's window is scanned at 1–2 m from the pavement — 10–20 cm of code — and its highest value is when you are shut. Someone walking past at 8 pm who can book on the spot is a booking you would otherwise lose.
Say so on the decal: "Closed? Book online" outperforms a bare code substantially.
Mount it inside the glass facing out so street reflections sit in a different focal plane, and use matt vinyl.
At the mirror
A rebooking code at each station, scanned while the client is waiting for colour to develop. Point at your booking system with the stylist preselected if your system supports it.
On the receipt
Google review code on the receipt or the card wallet. This is the strongest moment — the client has just seen the result.
Do not offer a discount for a review. Incentivised reviews violate Google's policies and risk both removal and a penalty on the listing.
Price list
If prices change often, a code pointing at a hosted price list saves reprinting the window card each time. Use a stable URL you update in place.
