How Does the QR Code Queue System Work? 

Incorporating a QR Code Queue System streamlines the queuing process, offering a convenient and efficient solution for businesses and customers alike. Here’s a step-by-step guide to how it operates.

  1. QR Code Scanning: Customers initiate the process by scanning a QR code prominently displayed at the venue. This QR code serves as the gateway to the virtual queue.
  2. Virtual Queue Assignment: The QR code queue system is integrated with sophisticated queue management software. This system assigns a unique digital ticket to each customer, indicating their precise position in the queue.
  3. Real-time Updates: Customers receive timely smartphone notifications, providing up-to-date information about their queue status. This eliminates the need for physical waiting and allows customers to maximize their waiting time.
  4. Approaching the Service Point: When it’s a customer’s turn, they receive a notification prompting them to approach the designated service point. This seamless process ensures a smooth and contactless transition.

By leveraging QR code queue systems, businesses can effectively manage customer flow, optimize service efficiency, and provide an enhanced experience for their patrons. This innovative solution reduces physical queues and aligns with the modern preference for convenient and tech-savvy interactions.

Benefits of Using a Queue Management System QR Code

Now that we know how a QR code queue system works let’s look at the advantages a business and customers can enjoy with its deployment.

1. Customers can opt for contactless check-ins

Queue management systems with QR codes allow customers to make an appointment or reserve their spot. 

Customers do not have to wait, and it minimizes the need for physical contact. This is particularly useful in hospitals for patients and hotels for guests to enjoy a hassle-free check-in process.

Customers are given a QR code to scan using a phone’s camera or a QR code scanning app. This QR code is often presented via email, text message, mobile application, or a banner outside your facility. 

Customers are directed to a web page or app after scanning the QR code, where they check in and enter personal information, such as their name, contact information, or reason for their visit. Customers receive a confirmation message upon completion of the check-in procedure.

2. Virtual Mobile Ticketing

Queue management systems can integrate QR codes to provide customers with an online ticketing process. You can provide your customers with a ticket number generated through the QMS on the phone instead of making them wait in lines to reserve a spot. This cost-effective solution saves you from investing in ticket machines and wasting paper.

3. Customers enjoy faster check-in times

Customers can quickly and easily scan QR codes, which reduces wait times and improves the efficiency of the queue management system.

On the contrary, physical queueing requires customers to manually fill in personal information on paper or wait in line to communicate that information at the counter.

4. Prevent overcrowding in waiting areas

Integrating QR code queueing into your system is a straightforward method to control crowd size. High-quality, high-contrast QR codes allow scanning from several meters away. 

Linked with QMS, customers enjoy virtual queueing, knowing precisely when it’s their turn. With a defined QR code text limit, this system guarantees an efficient customer experience.

5. QR codes are error-free and improve accuracy

QR codes eliminate the risk of errors that can occur with manual check-in processes, such as typos or incorrect data entry when filling forms with personal information.

6. A multipurpose solution that can be used in different settings

QR codes find applications in diverse settings, from clinics to retail stores. They efficiently guide customers to your company’s landing page, facilitating sign-ups for virtual queuing and introducing other Calls to Action (CTAs). 

Employing QR code queue systems enhances customer experience, ensuring seamless queuing. Additionally, integrated with people counting, these systems provide valuable insights for efficient crowd management.

7. Cost-effective solution by using staffing resources efficiently

Implementing a QR code in a queue management system is more cost-effective than hiring additional staff to manage queues manually. 

It also reduces the need for printing physical tickets and other materials, saving money on paper and ink. QR codes are inexpensive to produce and can be easily printed or displayed on digital screens, making them a cost-effective option for businesses of all sizes.

8. Enhanced customer experience

A contactless and streamlined queuing process with QR codes means less customer queuing anxiety. They do not have to worry about arriving hours early at the facility to reserve spots. 

This, in turn, helps to improve the overall customer experience and boosts satisfaction by providing a contactless and streamlined queuing process with your company.

9. Real-time updates with data

QR codes can be integrated with queue management software to provide real-time data on wait times, customer flow, and other metrics. Customers scan the QR code to find their position in the virtual queue, estimated wait time, and any delays. 

With QR codes, customers will know when it is their turn to be served, minimizing the need for physical waiting in busy places. This has made tracking service times and recording each customer’s projected service time easier for businesses.

How To Use Queue Management System QR Code At Your Business?

Choosing an ideal QMS is a challenge for which you must consider certain factors. We have simplified the process for your ease. Let’s follow the steps:

You first need to choose a QMS service provider that fits your real-time updates, notifications, and analytics requirements. It is critical to select a vendor with a centralized managed QMS system, globally known for its scalability. Choose a QMS that can integrate third-party apps to display QR codes and promote virtual mobile ticketing.

Once you have decided on a supplier, you should collaborate closely with them to customize the QMS to your unique needs. This procedure includes tailoring a roadmap of queuing, branding it to your company’s needs, and including the QR code in the design.

QMS is offered on two systems: a cloud-based system requiring little hardware and an on-premise system requiring a more thorough installation. The system generates a unique QR code for each customer or transaction, which the customer can scan to join the queue. Print the codes, or install screens with QR codes and post them in prominent places near the door, service counters, or waiting areas where customers can instantly scan them.

Train your employees on correctly using QR codes within the QMS so they can communicate and encourage consumers on the advantages of virtual queuing with QMS. Use your QMS’s analytics to track line length, wait times, and customer feedback. This data can assist you in optimizing the queue and improving the overall client experience.

Examples of Queue Management System QR Codes in Practice

If you have been wondering what it means for businesses to adopt a QMS with QR codes, the case point from a leading global fashion retailer, Zara, will speak of the system’s success.

The much-awaited opening of stores post-pandemic was met by Zara and its parent company, ​​Inditex, investing in measures to maintain social distancing. The company had to adopt techniques to minimize contact and regulate store occupancy for maximum safety of the staff and the customers.

To solve the significant wait times and complaints in stores, especially during peak hours, Zara partnered with Wavetec to implement the WhatsApp Queuing Solution. The two main features of this include a virtual queuing system and a mobile app. This QR code-integrated QMS offers visitors QR codes to scan, open WhatsApp, and chat instantly. Customers will receive a virtual ticket for their choice of service, after which they immediately join a queue to reserve a spot.

Powered by Spectra for alerts and analytics, Wavetec allows WhasApp’s QR code QMS to be integrated with other tools. Following this, the Zara store also installed digital signages and SMS notifications to keep clients updated on expected wait times and any changes to queue status. With this technology, it was able to offer priority waiting queues, entertain multiple customers simultaneously, and keep customer satisfaction high.

Case in Point!

Wavetec has successfully deployed and operated visitor management systems in retail stores like Nike and in public offices like the City Hall in Colmenar. The proof is in the consumer trust and confidence, especially in times when neither is in too high a supply.
