Retailer Carrefour uses blockchain technology to enhance sales

Retailer Carrefour has achieved sales growth by the use of blockchain ledger technology to track meat, milk and fruit from farms to stores, Reuters reported.

Carrefour has launched blockchain information for 20 items including chicken, eggs, raw milk, oranges, pork and cheese, and will add 100 more this year with a focus on areas where consumers want reassurance, like baby and organic products.

“You are building a halo effect – ‘If I can trust Carrefour with this chicken, I can also trust Carrefour for their apples or cheese,’” Emmanuel Delerm, Carrefour’s blockchain project manager, told Reuters at a conference.

Carrefour is among several leading companies tapping into the growing use of blockchain to track where products come from, as consumers increasingly look to ensure that products meet standards on ethics and general safety.

Carrefour has worked on the blockchain system together with IBM, which is collaborating with a number of retailers, logistics firms and growers on systems to track and secure their global supply chains.

Customers can scan a QR barcode on a pomelo grapefruit with their phone and find out the date of harvest, location of cultivation, the owner of the plot, when it was packed, how long it took to transport to Europe and tips on how to prepare it.

“The pomelo sold faster than the year before due to blockchain,” Delerm said. “We had a positive impact on the chicken versus the non-blockchain chicken.”

The initiative has proved most popular so far in China – where it is already common for shoppers to scan QR codes, followed by Italy and France, with some people spending as long as 90 seconds reading the provenance information.

There are still challenges to overcome, such tracking fruit and vegetables sold loose that come from different farms, and resistance from farmers to sharing too much information, he added.

Carrefour wants to add non-food lines in future like clothing, as well as more information, such as how much the farmer gets out of the shelf price. It is also experimenting with ways to identify products that do not rely on a QR code.

While Carrefour is focusing the project on its own brands, it has also worked with Nestle on giving consumers access to blockchain data for its Mousline potato puree, allowing them to see it is only made from French potatoes.
