The UK grocery sector is on the brink of a technological leap forward as Morrisons partners with Instacart to launch AI-powered Caper Carts, also known as smart shopping trolleys. This innovation represents more than just a high-tech gimmick — it signals a structural shift in how supermarkets plan to blend artificial intelligence, retail automation, and customer experience personalization into everyday shopping.
What Are AI-Powered Smart Shopping Trolleys?
Instacart’s Caper Carts are intelligent shopping trolleys fitted with computer vision cameras, weight sensors, barcode scanners, and touchscreens. Unlike standard self-checkout, these carts recognize products as shoppers place them inside, calculate accurate totals in real time, apply loyalty discounts, and even allow instant payment on the cart.
This technology removes the need for traditional checkout lines, making shopping faster, more convenient, and data-driven. Customers benefit from:
- Live basket totals for smarter budget management.
- On-screen personalized coupons and product suggestions.
- Integrated store maps that guide them to products efficiently.
- Contactless payment options, enabling a walk-out shopping experience.
The Business Case: Why Retailers Want Smart Trolleys
Morrisons isn’t simply chasing a trend. AI-powered trolleys unlock new value in three ways:
- Checkout-free efficiency – shorter queues and smoother store flow.
- Retail media revenue – in-cart screens create a fresh advertising channel for FMCG brands.
- Data-driven operations – real-time insights into customer behaviour, inventory gaps, and aisle traffic patterns.
- Customer loyalty – personalized discounts and digital shopping lists strengthen engagement.

A Look Back: The Journey of Smart Cart Technology
- 2016–2019: Startups like Caper, Trigo, and AiFi pioneered smart cart and checkout-free concepts.
- 2020–2021 (Pandemic Shift): COVID-19 amplified the need for contactless checkout. Instacart acquired Caper AI in 2021, signalling its commitment to in-store innovation.
- 2022–2025: U.S. grocery chains including Kroger and Fairway tested large fleets of smart carts. Retailers began integrating retail media opportunities directly into the cart interface.
- 2026 and beyond: The Morrisons pilot will mark the first UK deployment of Instacart’s Caper Carts, positioning the UK as a major testing ground for AI-driven retail automation.
Costs and Economics of Smart Carts
While customers don’t pay to use smart trolleys, the investment for retailers is substantial. Industry estimates suggest:
- Hardware cost per cart: between US$5,000–$10,000 (approx. £3,700–£7,400 in the UK, €4,250–€8,500 in Europe, A$7,500–A$15,000 in Australia, ₹4.4–₹8.8 lakh in India).
- Full-store rollout: often hundreds of thousands of dollars once integration, staff training, software, and maintenance are included.
Despite high upfront costs, the return on investment comes from reduced staffing needs, increased basket sizes, and ad revenue from on-screen promotions.

Risks, Regulations, and Customer Concerns
With every innovation comes scrutiny. Key challenges include:
- Data privacy and GDPR compliance – smart trolleys use cameras and sensors, requiring strict safeguards to avoid personal data misuse.
- Loss prevention – ensuring accuracy in item recognition and preventing misuse or fraud.
- Labour impacts – automation may reduce cashier roles but create new tech-support positions.
- Adoption barriers – some shoppers may resist AI-driven experiences due to privacy or usability concerns.
The UK’s Information Commissioner’s Office (ICO) will likely review such deployments under GDPR rules, making Morrisons’ rollout a case study for balancing innovation with compliance.
Competitor Landscape: Who Else Is Innovating?
- Instacart / Caper Carts: Hardware-first, cart-based checkout with strong retail media integration.
- Trigo: Computer-vision ceiling cameras enabling just walk out store formats.
- AiFi: AI-powered autonomous stores, often used in travel hubs and small-format retail.
- Grabango (Exited 2024): Once a competitor, now a cautionary tale of the challenges in scaling AI checkout solutions.

What This Means for UK Shoppers and the Future of Retail
For Morrisons customers, this pilot will mean faster, more seamless shopping trips with personalised discounts at their fingertips. For the UK grocery sector, it’s a litmus test of how British consumers accept AI-driven trolleys compared to traditional self-checkout or scan-and-go apps.
If successful, expect rivals such as Tesco, Sainsbury’s, and Asda to accelerate their own smart cart or checkout-free experiments. The bigger picture? AI-powered trolleys could become as common as self-checkouts are today.
