Summarize with

Customers scan a QR code, get notified through LINE, and no personal data is required. Queue management just got simpler with GO CAYIN poster x Call Me Back.

Without a queue management system, a crowded waiting area often pushes customers to walk away before they are even served. Without visible number updates, customers stand around feeling uncertain, while staff are constantly interrupted with the same question, what number are we on now. For restaurants, clinics, government service counters, and banks, this is not just a comfort issue, it directly affects turnover and service efficiency.

With the integration with Call Me Back feature available in GO CAYIN poster, you can now connect Call Me Back's cloud based queue management system directly to your digital signage screen, showing live queue numbers alongside your content.

Customers simply scan a QR code on site to take a number and receive queue updates through LINE, with no personal information required. When it is their turn, a notification is sent automatically and the on screen display updates in real time, making the wait smoother and more transparent for everyone.

How It Works

Step 1: Activate your account with Call Me Back to receive a unique merchant code, one letter followed by four digits.
Step 2: Log into GO CAYIN poster and open the integration with Call Me Back field in the editor.
Step 3: Enter your merchant code to display live queue information on screen.
Step 4: Use poster's template library to design and update promotional content around the queue display anytime.

Café customer scans a QR code to join the queue instantly through LINE.
