# QR code check-in

QR code check-in lets a customer scan a printed code with their phone camera to join a waitlist, with no app to install and no paper to sign.

Also called: scan to join, QR waitlist, scan-to-check-in

A QR code is a square that holds a web address. When a customer points their camera at it, the phone opens that page. For a walk-in shop, the page is a join form, and the result is a place in line created from the customer own phone.

The practical effect is that the line moves out of the lobby. A customer can scan at the window, step outside or sit in the car, and watch their place update. Your waiting area stays calm, and a crowded Saturday does not force people to stand.

Placement is what makes it work. Put the code on the door, the window and the counter, large enough to scan from a short distance, with a few words that explain it. A code printed small on a back wall gets ignored.

## How NextUp Walk-in handles it

Customers scan the location QR code, enter a first and last name, choose services and a team member, and join the line. No app is needed. The QR code can be printed from the setup guide, and the TV shows one when the line is empty.

## Questions

Do customers need an app to scan a QR code?

No. Modern phone cameras read QR codes directly and open the web page, so the customer does not install anything.
