The Future of Self-Order Kiosks: AI, Biometrics, and the New Era of Dining

Customer expectations have shifted over the years, especially in how we define personalization and convenience. You could say it’s partly a byproduct of the pandemic: Before, diners might’ve bristled at the idea of having robots and tech in restaurants, worrying it would remove the ‘human touch’—but now? That skepticism’s fading fast.

Kiosks and robotics are everywhere—in big chains, small diners, you name it.

In fact, experts say 2025 is the year we’ll see kiosks explode—in all shapes and forms—at our favorite spots. And with AI, biometrics, and contactless tech getting better every day, these tools are gonna shape customer experience even more. 

So let’s break down the tech behind this shift and see what’s next for kiosks.

Why Self-Order Kiosks Are Reshaping the Restaurant Industry

Self-order kiosks are no longer just a novelty for restaurants, big and small—they’re becoming a must-have for tackling big operational headaches:

1.  Labor Crunch Fix
   Kiosks allow customers to order solo, easing pressure on staff already stretched thin by labor shortages. Workers can then focus on creating genuinely delicious food or improving the customer experience by shifting their focus to problem-solving and catering to customized service.
   
2.  Bigger Orders Due to Upselling
   People tend to spend more when they tap a screen. Take McDonald’s—kiosk users drop $1 extra per order, bumping checks by 30%. Why? Because the recommendations feel natural and less forced compared to the usual staff push.
   
3. Improved Customer Experience
   Guests can customize at their own pace (gluten-free bun, extra sauce, hold the onions) with the help of kiosks, however, it can still be limited by coding constraints. Thankfully, however, most systems now handle complex requests better than ever.
   
4. Same Experience for  Every Location
   Whether it’s a highway stop or a downtown spot, kiosks serve the same menu, promos, and vibe. This uniformity ensures brand consistency and reliable service across all locations.

AI-Powered Kiosks That Actually Get the Customer

As mentioned, one big hesitation with adding too much tech is that it feels like it strips away the human interaction that’s core to service. Think about how a waiter immediately knows what the regulars order, or how a server recommends something new based on what the customer is craving. But here’s the thing: even the best waiter can only remember so much, and AI can expand on this even further.

Today’s AI models (at least as of writing!) can analyze past orders, time-of-day patterns, and even local weather to suggest hyper-relevant add-ons or meal combos. This means personalization isn’t just for regulars anymore—it can work for every guest, boosting repeat visits by up to 15-25% and hiking average order values by 20%. And the kicker? No awkward upselling from staff—just smart, subtle nudges.

Quick pilot tip: Start small. Test AI recommendations with a limited menu section (like desserts or seasonal specials) before rolling it out everywhere.

Biometric Payments: Faster, Smarter, Friction-Free

One of the most interesting restaurant campaigns in recent memory is KFC’s “Smile-to-Pay” campaign with Alipay in China. Customers had to log their orders and smile at a facial recognition device to process payments. At the time, it was a viral marketing stunt that boosted KFC and Alibaba’s local brand presence. But years later, we’re looking back at it as a trial run for the future—after all, it slashed checkout times by 30% and pulled in new customers thanks to the viral hype.

But let’s get practical: biometric payments (face, fingerprint, or iris scans) aren’t just about looking futuristic. When integrated into kiosks, they give restaurants a real operational edge:

• Cut card fees → no middlemen taking a cut.
• Speed up transactions → shorter lines mean happier customers.
• Boost loyalty → log customer data to personalize offers.
• Verify age → scanning for alcohol sales beats guessing a customer’s birthday.

Privacy note: Biometrics are powerful, but they’re sensitive. Regional laws like Singapore’s PDPA or the UAE’s GDPR-inspired rules mean that these factors  need to be considered first before incorporating them fully into kiosks:

1. Asking for clear consent
2. Data encryption
3. Delete data when done (don’t hoard face scans after a customer stops visiting).
4. Be transparent (explain how data’s used—no sneaky upsells based on their order history).

3D Kiosks: Turning Ordering into a Show

As much as we’d love kiosks to speed up service and wow customers with personalized recommendations, they’re also a golden chance for brands to double down on their brand experience. Take Subway Dubai’s 3D anamorphic screens, for example.

Customers can watch their sandwich come to life in 3D as they build it—like a mini culinary show right at their fingertips. This isn’t just a gimmick; it’s a core part of Subway’s Fresh Forward 2.0 concept, which is all about blending guest experience and convenience into one seamless, modern upgrade.

Voice Ordering: Real Conversations, Just Digitized

There’s no better way to address concerns about diminishing human interaction when incorporating technology than through actual conversation. This issue can be effectively resolved if self-order kiosks utilize advanced speech recognition, allowing AI to accurately process customer customizations. 

For restaurants, this can increase throughput, improve accessibility for visually impaired guests, and lessen the workload on the staff. This doesn’t necessarily mean it’s diminishing the quality of service. On the contrary, when tasks like taking orders and upselling are handed over to the kiosks, it can help staff focus more on improving their service by handling what humans do best: personalized care, solving unique requests, or just keeping the vibe welcoming.

Kiosks aren’t replacing hospitality. They’re reshaping it. And as they evolve—with AI, biometrics, 3D visuals, and voice—they’re becoming not just tools, but touchpoints. When done right, kiosks free up staff to focus on moments that actually require the human touch—resolving unique requests, interacting with guests, managing energy on the floor.
