Since introducing self-checkout systems in 2018, Carrefour has achieved a balanced usage rate of 50% between traditional and self-scanning checkouts.

Carrefour has expanded its self-checkout areas to approximately 120 stores, including franchises, while Delhaize reports that self-scanning now accounts for 60% of its transactions.

In response to significant losses, such as Jumbo's reported 100 million euros due to shoplifting last year, supermarkets are implementing new security measures, including AI to detect suspicious behavior.

Despite the theft concerns, many supermarkets, including Lidl, Cora, and Colruyt, are continuing to expand self-scanning technology in their stores.

However, the rise of self-scanning has been accompanied by an increase in theft, known in retail as 'démarque inconnue', as noted by Carrefour spokesperson Siryn Stambouli.

Jumbo is testing confrontation monitors at self-checkouts to deter potential thieves by allowing customers to see themselves scanning their items.

Delhaize also assesses unscanned products to determine if they were forgotten or stolen, occasionally redirecting customers back to traditional checkouts.

To combat theft, Carrefour has launched awareness campaigns for both employees and customers to educate them on proper self-scanning procedures.

Frequent offenders identified through loyalty cards may face increased scrutiny and potential bans from using self-scanning services.

In cases of discrepancies during random checkout controls, Carrefour employees may correct the transaction, but significant theft could involve police intervention.

While some franchises have discontinued self-scanning due to theft concerns, this remains a rare occurrence.
