Carrefour Belgium takes BuyBye autonomous fridges to a hospital operating theatre as network heads for 12 sites

Carrefour Belgium is taking its BuyBye autonomous store format to places where a conventional shop could not open, and the latest sites show what that means in practice. On 20 October 2026, the retailer announced two new BuyBye units inside the hospital in Charleroi. One sits at the entrance to the operating theatre block.

What has changed

Carrefour Belgium said it had opened two BuyBye stores at the hospital and that three more units in Lyon, run in collaboration with Carrefour France, will open soon. The release places the Lyon units at the city's railway station and airport. Carrefour says this brings BuyBye to 12 locations. The wording is worth reading carefully: the Charleroi stores are open, but the release describes the Lyon units as upcoming, so the 12 figure includes sites that are not yet trading.

A store the size of a fridge

These are not shops in the usual sense. At the hospital reception, BuyBye is a module of four refrigerated doors for staff, patients and visitors. At the operating theatre entrance, it is a module of three refrigerated doors. Carrefour says it was designed for the 200 to 300 care staff and technicians who work permanently in that area, so they can eat quickly without breaking off their shifts. Both units are run by the franchise partner that already operates the hospital's Carrefour Express store.

The range is built around fresh, quick food: ready meals, salads, sandwiches, complete meal options and sweet and savoury snacks. Carrefour describes BuyBye as an AI-guided autonomous concept serving 24/7 needs, and says it keeps prices competitive for users.

Why it matters for retail leaders

The site list explains the strategy. Besides Charleroi and Lyon, Carrefour names its Belgian head office in Zaventem, the Carrefour Express in Yvoir, Ibis hotels at Paris-CDG airport and Brussels-Midi, NATO's SHAPE base in Mons, MontLégia hospital in Liège and Corda Campus in Hasselt. These are mostly captive sites with people present at all hours. Food service there is often thin, and staffing a counter overnight is hard to justify.

For a convenience operator, this is a way to add points of sale through existing franchise partners without adding shop floor labour. The cross-border Lyon deal also suggests the format is moving from a Belgian experiment towards something the wider group is testing.

What would prove it

Arnaud Lesne, Innovation Director at Carrefour Belgium, said in the release: "Avec ce cap des 12 BuyBye, nous démontrons la maturité et la pertinence de notre modèle." In English, he says reaching 12 sites shows the model is mature and relevant.

The release gives no revenue, sales per module, shrinkage or usage data, and does not explain what the AI does in the shopping journey. Site count alone does not show a format is mature. The test for other retailers will be whether Carrefour shares how these fridges perform against a staffed kiosk, and whether the Lyon units open and trade as planned.
