Smart Supermarket: the Retail Revolution Is Already Here

What is a smart supermarket?

A smart supermarket is a store model that uses advanced technology to automate, optimise and personalise the shopping experience. Unlike a traditional supermarket, in these spaces there are no tills, no cashiers and no queues: you walk in, you shop, you leave. All of it through the integration of systems such as:

• Scanning and paying with your phone
• IoT sensors and smart cameras
• Artificial intelligence
• Automatic inventory management
• Real-time analysis of customer behaviour

These shops are the natural evolution of retail and are radically changing how everyday products get bought. Solutions such as Scan and Buy are opening up the 24/7 self-service model, combining inventory control, automatic payments and real-time data analysis.

Benefits of smart supermarkets

Benefit	Direct impact on the customer
Fast shopping	No queues, no waiting
24/7 opening	Always open, including public holidays
Better security	Fewer losses thanks to AI and sensors
Personalised offers	Through data analysis
Operational sustainability	Resource savings and optimisation

According to a McKinsey report on the future of retail, automation is no longer optional: it is central to cutting costs and improving the customer experience.

The key technology behind a smart supermarket

• Scan-and-pay app: the customer scans products with their phone and pays from the app.
• QR access door: only authorised people get in.
• Continuous AI monitoring: movement is recorded to prevent losses.
• Predictive analysis: shows which products need restocking and which will be in demand.
• Autonomous opening and closing: the supermarket runs without staff on site.

From computer vision to invisible payments, MIT Technology Review notes that smart supermarkets are bringing together several cutting-edge technologies at once.

24/7 supermarkets: is the model viable?

Yes, and it already is in many countries. From residential neighbourhoods to petrol stations, universities, hospitals and gated communities. The unstaffed supermarket concept is gaining ground because it:

• Cuts operating costs by up to 60 %
• Increases profit margin per square metre
• Allows growth through a franchisable model

What about Spain and Latin America?

Although the phenomenon started in countries such as the United States and South Korea, Spain and Latin America are seeing rapid growth in the autonomous supermarket model. Urban and tourist areas —the Costa del Sol, Madrid or Mexico City— are ideal, given their footfall and their convenience culture.

Scan and Buy: opening up smart supermarkets

One of the companies driving this change is Scan and Buy, a technology solution that lets any business set up its own 24/7 smart supermarket without a large upfront investment.

With Scan and Buy you can:

• Run your own store open 24/7, fully self-managed
• Personalise the app with your brand and your products
• Get detailed reports on sales, margins and stock rotation
• Offer users a smooth, secure experience

The model is also scalable and adapts to different formats: from small 15 m² shops to larger spaces, or integrations inside hotels, campuses and gated communities.
