Self Ordering Kiosk vs QR Code Ordering: Which Is Better for Restaurants?

Introduction

Inefficient vs. Quick and Convenient

Traditional ordering is often inefficient and error-prone, which has led to the rapid rise of self-ordering kiosks and QR code ordering. Whether restaurants opt for self-ordering kiosks or QR code ordering, both systems take advantage of the physiological trigger: “No Judgment” Zone. Modern customers prefer going out to grab a quick bite, but they prefer frictionless menu selection like the food delivery app they use at home.

Psychological Factor

The two systems: kiosk and QR code, in which one is interacting with the restaurant's machine, and one in which they use their own device, trigger a different psychological reaction. It's a fight between the internal desire to explore the physical world and deeply ingrained habits formed over the years through optimized apps, which is one of the reasons why guests may find both of them equally beneficial. Research by the Education University of Hong Kong concluded that 81.04 percent of young adults now prefer self-ordering mechanisms over traditional ordering methods.

For restaurants, it's a different question. They need to know where to invest their capital. To find out which one is better requires analyzing the two systems in various aspects, including operational efficiency, revenue impact, customer experience, ROI, and reliability. This article will cover all these aspects in detail.

Understanding the Systems Through Comparison

Self-ordering kiosks are dedicated hardware terminals with interactive screens where customers can browse, order, and pay independently. QR code systems allow customers to scan a barcode at their table with their smartphones, bringing up a digital menu to seamlessly order from their own devices.

1. Customer Experience

In this section, we will focus on the aspects that revolve around the customer experience. It includes comfort, privacy, and control over their order.

• Intuitive Interfaces: The large screens on Kiosks are highly intuitive. They are easy to understand, and you can switch between different languages to suit your most comfortable interface. People with allergies or low spice tolerance can define them early on to keep the menu clear of those options.
• Ultimate Convenience: Kiosks are superior in convenience. There is no need to carry a smartphone to the restaurants. Some people prefer leaving their screens behind to enjoy a meaningful conversation over dinner. Problems like a dead battery or no data plan do not exist when using a locally connected kiosk. They also have larger screens with accessibility features.
• The Case for QR Codes: QR codes are great for group ordering. Multiple people can order in the same cart at once. They create a hybrid preference among people who are comfortable with technology. Kiosks, on the other hand, are best for individual ordering.

2. Cost & Initial Investment

While customer convenience and comfort are the key factors for switching to digital technology, economic factors are equally important. The restaurant needs to survive in the rapidly shifting and dynamic restaurant market. To remain profitable, these digital technologies should make sense financially. Let's analyze initial investment and ROI in this section.

• Kiosk Investments: Kiosks are a larger initial investment. They require hardware and a network that requires expertise to set up. However, they provide rapid ROI. As there are limited cashiers, one or two are enough to take orders from clients who desire a human connection. They provide payroll savings, which contribute to their ROI.
• QR Code Economics: As there is no hardware investment required, they are an ideal choice for budget-conscious venues, for those restaurants aiming to switch to digital transactions and operations, fast QR codes are their fastest way in. Using codes doesn't save as much on labor, but they keep the monthly bills very low, usually just needing software updates.

3. Restaurant Size & Space Utilization

When choosing an ordering system, the scale of customer traffic is just as important as the size of the venue. Small restaurants generally rely on QR codes for a low-profile solution, while medium and large restaurants typically utilize self-service kiosks or a hybrid of both to manage higher volumes. For venues using kiosks, slim or wall-mounted designs save valuable space, allowing for more tables and increasing revenue per square foot.

4. Technical Requirements & Maintenance

There are technical details on how these technological devices share data, protect it, and ensure your software keeps running during rush hours. The whole system is designed with peak hours in mind. As restaurant owners, you will need to decide the number of customers during peak load, which includes online orders and dine-in requests. Here are some key features that these digital operating systems utilize:

• Peak Hours: Kiosks are hard-wired to the local network. It makes them more reliable than QR codes that rely on customers' signals and WiFi performance. During the peak period, connectivity drops can impact customer experience. Kiosks never see any hiccups.
• QR Failure Chances: As customers are ordering from their own device, there are multiple modes through which it can fail. A low battery, slow data plan, outdated phone, or bad local wifi can lead to a bottleneck.
• Security: Kiosks use AES security to protect payment information. They are also POS./KDS (Point of Sale / Kitchen Display System) devices that sync menus in real-time directly to the kitchen's available ingredients.
• Updates: The owners can push new updates or access the device remotely for maintenance. They may never require a technician to visit the store physically to perform a job.
• Compatibility: Kiosks are compatible with the restaurant's software. QR Codes rely on the customer's device. If it's an Android from 10 years ago, there can be compatibility issues.

5. Hygiene

Post-COVID-19, the working dynamics of the health sector and hospitality industry have been heavily impacted. Most people still prefer owning their own smartphones as they feel cleaner or more private. In fact, as per research by the Education University of Hong Kong in 2022, 45% young adults in Hong Kong prefer QR codes over kiosks specifically for this reason.

Most people avoid getting into awkward interactions with others. Kiosks and QR codes equally help people with social anxiety issues and provide a clear and written pick up instruction. They do not want somebody calling out their name out loud.

6. Operational Speed, Throughput & Revenue Impact

The key to a successful system is its impact on the operational speed of a restaurant. It should directly solve the problems that can result in speed and flow issues. Here are some ways digital transactions improve performance:

• Parallel Ordering: Kiosks can work together in parallel, handling multiple customers at different stations. This provides a highly accelerated ordering pace at the front of the house compared to QR codes, where diners may take longer to scan, browse, and finalize their group's orders at the table.
• Accurate Order to Kitchen: Kiosks are directly connected to the kitchen prompter, instantly registering exact inputs. Both kiosks and QR codes excel in this area by sending precise, digital order tickets straight to the preparation line, ensuring flawless accuracy.
• QR Code Reliance on Internet: Using QR codes is great for convenience. You don't have to get up from your seat. However, it depends on the internet. Slow internet or disruption of the internet can cause the system to crash or glitch.
• Complex Orders: Requests for extra toppings, no onions, or allergy alerts are easily managed digitally. Both kiosks and QR code systems capture these personalized modifications perfectly and deliver the exact requirements straight to the kitchen.
• Pre-Ordering: As per research done by Yi Ting (2022), in Hong Kong, younger people prefer QR codes for their pre-arrival ordering feature. It helps them with zero waiting or standing in line.
• Kiosk Ease of Use: As per UTAR's empirical study on self-service kiosks, people give kiosks 4.27 out of 5. They are fast improving operational flow. They follow a psychological theory called the extended TAM model.

7. Maximizing Revenue: Upselling and Engagement

Using digital tools in restaurants allows customers to freely explore options and encourages them to spend more. Specifically, Kiosks with their high-resolution screen give bright images and combo prompts to engage customers. The menu looks much better with interactive objects rather than plain text on a standard menu. Appetizing animations lead to more impulse purchases.

In comparison to a tired employee who might forget something, the machine works tirelessly 24/7. They are always suggesting and improving order margins through upgrades and limited-time deals.  As per a UTAR study, kiosks are fun to interact with. The colorful pictures increase the perceived enjoyment. It concluded R2=0.661, which means 66.1% people adopt kiosks for their factors like enjoyment.

Comparing Core Features

Scenario-Based Recommendations

We avoid presenting one as strictly better than the other. Selecting either of the digital technologies depends on its application. Kiosks and QR code systems depend on the restaurant's functional style, customer age, and the habits of the guests. Based on various circumstances, here are our recommendations:

• Kiosks: Require hardware investment and maintenance, but they are highly suitable for high traffic and diverse customers. They lead in handling the number of customers served at a particular time, and impulse upsells. This makes them widely successful in regions like Europe, the US, and some developing countries.
• QR Codes: They rely purely on smartphones, offering a low cost and flexible option to restaurants aiming to modernize their traditional table service. They are suitable for smaller venues or budget-limited cases and are highly common in East Asia and Southeast Asia.
• The Hybrid Model: Using a hybrid model is often the best solution and the most effective strategy, especially for medium to large restaurants during peak hours. It provides customers with ultimate freedom. They can switch between the two technologies based on mood and environment.
