As a major industry player with a large global footprint, Carrefour is always looking for new ways to improve customer service and streamline operations. Providing comprehensive and detailed information about the nature and origin of their products not only sets them apart from the competition, it also enables them to build trust and drive demand with their more than 100 million customers worldwide who are becoming more invested in knowing as much as possible about the quality and sourcing of their groceries.
By partnering with IBM, Carrefour is able to leverage blockchain to provide unprecedented transparency to consumers about their food’s journey. Shoppers can scan a QR code on the food label or packaging with their smartphones and access information permissioned for consumers such as date of harvest, location of cultivation, when it was packed, safety tests and certifications, and even tips on how to prepare it. Carrefour told Reuters in June 2019 that it had implemented this initiative with a growing number of products, including chicken, eggs, milk, oranges, pork, cheese and more.
Carrefour has seen sales boosted by the use of blockchain ledger technology to track meat, milk and fruit from farms to stores and will extend it to more products to increase shopper trust. Carrefour’s blockchain project manager Emmanuel Delema notes, “You are building a halo effect — ‘If I can trust Carrefour with this chicken, I can also trust Carrefour for their apples or cheese.’”
