Can you compare touchless versus touch kiosks and outline the pros and cons for each?

 Self-service kiosks are used in many public and semi-public environments to handle tasks such as payments, check-ins, ticketing, and account management. As these systems have evolved, two broad interaction models have emerged: traditional touch-based kiosks and touchless kiosks that rely on alternative input methods. Each approach is shaped by different technical, environmental, and user experience considerations. Comparing them helps clarify where each model may be more appropriate.

Touch kiosks are built around direct physical interaction with a screen or keypad. Touchless kiosks, by contrast, aim to reduce or eliminate physical contact, often using technologies such as proximity sensors, gesture recognition, mobile device integration, or voice commands. While both serve similar functional purposes, their strengths and limitations differ in practical ways.

Touch kiosks

Touch kiosks rely on users physically pressing icons, buttons, or keys on a screen or control surface. This model has been widely adopted over the past two decades and is familiar to many users.

One advantage of touch kiosks is their intuitive nature. For users accustomed to smartphones, tablets, or ATMs, touching a screen to make selections requires little explanation. Visual feedback is immediate, and interfaces can be designed to guide users step by step through a process. This familiarity can reduce errors and shorten transaction times, especially in environments with repeat users.

Touch kiosks also tend to be less complex from a technical standpoint. Touchscreens are a mature technology with well-established manufacturing standards and support ecosystems. Maintenance, while necessary, is generally predictable. Replacement parts and repair procedures are widely available, which can simplify long-term operation.

However, touch kiosks have drawbacks. Physical contact means surfaces can accumulate dirt, moisture, and wear. In high-traffic locations, screens may require frequent cleaning to remain usable and hygienic. Over time, repeated tapping can degrade responsiveness, leading to calibration issues or reduced accuracy.

Accessibility can also be a mixed issue. While touch interfaces can be designed with large buttons and clear layouts, they may still pose challenges for users with limited dexterity, mobility impairments, or certain visual conditions. Gloves, wet hands, or environmental factors such as direct sunlight can further reduce usability.

Touchless kiosks

Touchless kiosks aim to address some of these limitations by removing the need for direct physical contact. Interaction methods vary and may include hand gestures detected by cameras, motion sensors that register hover-based input, voice recognition, or the use of personal mobile devices to control the kiosk remotely.

One commonly cited benefit of touchless kiosks is reduced surface contact. In shared environments, this can lower the need for constant cleaning and may help maintain consistent operation over time. Components such as screens may experience less physical wear, potentially extending their service life.

Touchless systems can also support flexible interaction patterns. For example, users may be able to complete transactions from a short distance or use their own devices to input information. In some settings, this can streamline workflows or allow multiple users to interact with a system in different ways.

At the same time, touchless kiosks introduce new challenges. Gesture-based systems require clear instructions and sufficient space for accurate detection. Users unfamiliar with these interactions may hesitate or make unintended inputs, especially if feedback is delayed or unclear. Voice-controlled systems can struggle in noisy environments, while camera-based solutions raise privacy considerations that must be managed carefully.

Technical complexity is another factor. Touchless kiosks often rely on multiple sensors and software layers, increasing the potential for calibration issues or compatibility problems. Maintenance may require more specialized expertise compared to traditional touchscreens. Environmental conditions such as lighting, background movement, or network reliability can also affect performance.

For a broader discussion of how different kiosk interaction models are applied in shared-service environments, including operational considerations, readers may find this detailed explanation useful.

Comparative considerations

When comparing touch and touchless kiosks, context plays a significant role. Touch kiosks may be better suited to environments where speed, familiarity, and straightforward maintenance are priorities. Locations with stable lighting, controlled access, and regular cleaning schedules often align well with touch-based systems.

Touchless kiosks may be more appropriate where minimizing physical contact is a design goal or where users benefit from interacting at a distance. They can also complement touch systems rather than fully replace them, offering multiple input options within a single installation.

Cost considerations differ as well. Touch kiosks generally have lower upfront costs due to standardized components. Touchless kiosks may require higher initial investment but could offset some costs through reduced physical wear or expanded functionality, depending on usage patterns.

User expectations should also be considered. Some users prefer the certainty of physically pressing a button, while others may appreciate hands-free interaction. Clear signage, consistent feedback, and fallback options can help accommodate a wider range of preferences regardless of the chosen model.

Overall, neither approach is inherently superior in all situations. Touch and touchless kiosks represent different responses to usability, hygiene, maintenance, and technological trends. Evaluating their pros and cons in relation to specific operational needs, user demographics, and environmental conditions is essential when deciding which interaction model to deploy.

How many machines do you need for a profitable laundromat?

 Running a laundromat isn’t just about filling a room with washers and dryers—it’s about balancing capacity, customer demand, and profitability. The number of machines you need depends on location, demographics, and your business model, but there are industry benchmarks that can help you plan smartly. How many machines does a profitable laundromat usually need? Most profitable laundromats operate with 40–100 machines in total , typically split between washers and dryers. A rough rule is to have one dryer for every washer (or slightly more dryers) , since drying cycles often take longer. Small laundromats (20–30 machines) work in suburban or low-density areas with steady but modest demand. Medium laundromats (40–60 machines) strike the balance, common in busy neighbourhoods or near apartments. Large laundromats (70–100+ machines) cater to high-traffic urban locations, often doubling as community hubs. A common profitability benchmark is aiming for at least 3–5 turns...

Cutting Costs in the Wash: Energy-Saving Tips for Laundromat Owners

 Why are your energy bills rising faster than your customer base? For laundromat owners, this isn’t just frustrating—it’s a direct hit to already tight margins. And here’s the kicker: a huge chunk of those rising costs? They’re baked into your washers and dryers. But the good news? You can slash those bills without cutting service. Let’s unpack some energy-saving moves that actually work—and how smarter laundromat management plays a hidden role in all of it. How much energy do laundromats really use? Short answer? A lot. An average laundromat in Australia chews through 1,000–2,000 kWh of electricity daily , primarily from washers, dryers, and hot water systems. That’s roughly the same as 50–70 homes. And with electricity prices seeing double-digit jumps in recent years, you’re not imagining things—it’s costing you more to keep the lights (and dryers) on. And let’s not forget water heating— about 15–20% of your energy bill is just from heating water. That’s where things star...

What happens if a machine only takes cards?

 Some businesses proudly hang a “card only” sign. No coins, no notes, no exceptions. For customers, that can feel either like modern convenience or like being shut out entirely. For laundromats especially, the question looms: what actually happens if a machine only takes cards? The short answer: it streamlines payments, reduces theft, and matches how most Aussies already pay. But it can also alienate segments of the community who still rely on cash. The balance between efficiency and accessibility is what makes this debate so interesting. Why are laundromats going cashless? Australia is one of the fastest adopters of cashless payments. More than 80% of everyday transactions are now made with a card or digital wallet, according to the RBA. For a laundromat owner, switching to card-only payments means: Less time spent collecting, counting, and banking coins Reduced theft risk (no bulky coin hoppers to target) Faster transactions and fewer machine jams Cleaner faciliti...
