Smart grocery stores are reshaping the way people shop at a pace few could have predicted. By the end of the year, more than 18 million shoppers in the United States will use grocery apps each month, reflecting nearly 50 percent growth compared with last year. What began as a trend in large metropolitan areas has quickly expanded to suburban supermarkets and beyond.
The surge in digital innovation has transformed both the customer journey and store operations. Research shows that 87 percent of grocery executives expect marketing to evolve into hyper-personalized experiences, while 71 percent believe technology will help them capture a greater share of their customers’ daily lives. In practice, these shifts are already visible. Kroger’s Scan, Bag, Go system is now active in 400 stores, and smart carts equipped with touchscreens can guide shoppers and calculate bills in real time.
This article examines how smart technology is redefining grocery shopping, why frictionless checkout is becoming a standard expectation, and how behind-the-scenes systems are streamlining store operations. Readers will gain insight into why some retailers are thriving while others struggle, and what lessons can be drawn from the most innovative players in the market.
Smart technology is reshaping the grocery experience

The battle for retail supremacy has reached store aisles, where state-of-the-art technology changes how we shop and pay for groceries.
Digital shelf displays and up-to-the-minute pricing
Paper price tags are disappearing faster than ever. Walmart leads this change with plans to roll out digital shelf labels (DSLs) across 2,300 stores by 2026. Store teams now update prices in minutes instead of spending two full days on the task.
These displays bring remarkable adaptability to pricing. Some European grocery chains adjust their prices up to 100 times each day to stay competitive. Staff members use “Stock to Light” and “Pick to Light” features to find items that need restocking or products for online orders quickly.
Shoppers respond well to this technology. About 80% say they’re more likely to buy products when they can scan information codes on digital displays.
Smart carts and in-aisle product guidance
Smart shopping carts mark another innovation in grocery tech. Nearly half of surveyed grocers plan to assess them within the next year.
Smart carts pack powerful features with their built-in sensors and cameras:
- They identify products automatically without scanning
- Produce weighing happens right in the cart
- Built-in maps guide shoppers through stores
- They recommend matching products and show current deals
The best part? Customers can pay right at their cart and skip the checkout lines completely.
Mobile apps for tailored shopping
Grocery apps have become must-have shopping tools. AnyList stands out with its impressive 4.9-out-of-5-star rating. Shoppers create and share lists that update instantly when family members make changes. Many apps connect directly to retailers like Walmart and Kroger, letting customers order groceries without switching platforms.
Smart grocery apps help plan meals and create shopping lists automatically. Target Circle shows exactly where items sit on store shelves. This saves time and eliminates random searching through large stores.
Frictionless checkout is becoming the new standard

Checkout has evolved into the final frontier of grocery breakthroughs. Retailers are rushing to eliminate the most frustrating part of shopping—waiting in line. The global self-checkout market is growing faster and will reach $13.98 billion by 2030 with a 16.2% annual growth rate.
Scan-and-go mobile tools
Walmart, Sam’s Club, and ShopRite now accept new ideas with scan-and-go technology. Shoppers can scan products with their smartphones while they shop. The system creates a virtual cart with live totals that has discounts and loyalty rewards. Customers can pay through the app or at a designated area and skip traditional checkout lines completely.
Computer vision and Just Walk Out systems
Amazon’s Just Walk Out technology stands out as the most advanced solution. It combines AI, cameras, and sensors to track customers’ selections and returns to shelves. The process is simple – enter the store, take what you want, and leave. Your account gets charged automatically. Lumen Field’s results prove the success – an 85% increase in transactions and a 112% boost in sales after implementing this technology.
Online ordering systems built for grocery stores
Grocery stores now provide dedicated solutions that connect digital shopping with in-store operations. An online ordering system for grocery, such as the one offered by Wave Grocery, allows customers to create virtual carts from home and choose either pickup or delivery.
Beyond convenience, these platforms bring a range of benefits to both shoppers and store owners:
- Direct ordering from the store’s own platform instead of relying on third-party marketplaces
- Access to detailed product information and nutritional data
- Integrated loyalty programs with personalized discounts
- Options to communicate with in-store shoppers about substitutions
Self-checkout kiosks vs. mobile-first models
Self-checkout kiosks are common now but they have drawbacks. They need much hardware investment and valuable floor space. They often create bottlenecks during busy times. So many smart grocery stores now change toward mobile-first checkout models that use customers’ devices. This eliminates fixed checkout points and reduces congestion—especially during peak shopping hours.
On top of that, mobile checkout solutions update inventory live and deliver tailored promotions to each shopper. This creates a win-win situation for customers and retailers alike.
Behind-the-scenes tech is driving efficiency

Complex technology powers the smooth customer experience you see in modern grocery stores. Data-driven systems quietly streamline retail processes through the operational backbone of smart grocery stores.
AI-powered inventory and demand forecasting
Predictive analytics and artificial intelligence have become essential tools for inventory management. These systems analyze historical sales data to predict demand changes and reduce waste. This method cuts out-of-stock incidents by 20-30% compared to traditional manual approaches. McKinsey’s research shows robots detect out-of-stock situations 14 times better than human scans.
These AI forecasting systems deliver remarkable results:
- Fresh product waste drops by up to 30%
- Forecast accuracy improves for 90% of SKUs
- Inventory costs decrease by about 10%
The core team can now focus on helping customers instead of repetitive tasks like scanning shelves and updating prices.
Dark stores and robotic fulfillment
Dark stores have created a radical alteration in grocery operations. These retail spaces serve online orders exclusively and stay closed to the public. You won’t find checkout counters or sales floors here – just streamlined picking systems.
Amazon leads this trend by testing mini-warehouses next to Whole Foods locations. Their robots collect items for customer pickup. Finally has also created robotic “store fulfillment centers” that help existing grocery stores adapt to omnichannel retail.
The numbers make sense: dark store picking costs £12 per grocery order, substantially lower than traditional stores’ £18-£20 cost.
Grocery technology in supply chain optimization
IoT sensors now reshape maintenance and monitoring throughout the supply chain. Smart systems can predict when equipment might fail, which cuts downtime and maintenance expenses. Grocers use sensors in coolers and freezers to spot maintenance needs before operations stop. This technology boosts team productivity by 1.5% across store networks.
The North American food robotics market hit $842.94 million in 2023. Experts project this will reach nearly $1.94 billion by 2032. These investments show how technology reshapes grocery operations and creates unprecedented efficiency from warehouse to checkout.
Why some stores are falling behind
Modern technology keeps moving forward, yet many grocery retailers remain stuck in outdated operational models. As a result, the divide between innovative and traditional stores grows larger each day. Several factors explain why some retailers struggle to keep pace:
- Failure to adapt to changing consumer behavior: Grocery prices have risen nearly 30 percent since 2019, and shoppers are more focused on saving money than staying loyal to brands. Research shows that 57 percent of customers are willing to switch stores for better deals. Retailers that still aim at the “average” customer overlook the diversity of household types and evolving shopping priorities.
- Overreliance on legacy systems: Many grocers still depend on outdated custom technology that is expensive to maintain and slow to update. Without reliable internet infrastructure or modern platforms, updates can take four times longer and cost ten times more than they should, preventing stores from creating new solutions.
- Lack of investment in digital infrastructure: Profit margins in grocery average just one to three percent, leaving little room for innovation. Limited technical resources and a shortage of AI expertise stop many retailers from implementing essential digital tools.
- Ignoring sustainability and local sourcing trends: Sustainability now drives more purchase decisions, with 95 percent of consumers aiming to live more sustainably. Yet 26 percent report difficulty finding sustainable products online.
Looking Ahead at the Grocery Landscape
The grocery industry is entering a period where innovation decides success. Stores that embrace smart technology are not just improving the customer experience, they are also strengthening operations behind the scenes. Shoppers now expect convenience, personalization, and sustainability, and the retailers who deliver on these expectations will stand out in a crowded market.
The lesson is clear: adapting to change is no longer optional. Those who invest in digital tools, streamline operations, and connect with consumer values will thrive. Those who resist risk being left behind as the next generation of smart grocery stores sets new standards for efficiency, service, and loyalty.
