Carrefour Increases Mobile App Engagement 400% With Proximity & Beacons

Carrefour, the $20B+ multinational retailer, has been using mobile apps since 2012. The purpose of one of these apps was to make the shopper experience easier and more efficient by helping them find new stores and check prices on items with a mobile phone. It may not be the sexiest of apps, but definitely a useful one. After 2 years, Carrefour added proximity and context to their app with Bluetooth beacons and saw that the exact same application’s engagement went up 400%, virtually overnight!

Rethinking mobile marketing

Pixels Trade, a Swiss interactive agency, pitched Carrefour on the potential power of adding context to their existing mobile app, and Carrefour decided to give it a try.
Pixels Trade deployed about 50 beacons in one store in Tunisia and integrated the existing app with’s API. The goal was to enhance customer experience, boost engagement, and eventually, to increase sales. There were no key indicators or expectations. Either Carrefour and the agency treated it as an experiment. In October 2014 the project launched.
What actually happened surprised them both.

Measuring “the power of proximity” beacons enriched the app and Carrefour shopping experience with new features, including welcoming  a shopper  once he or she enters a store, suggesting products based on previous or current purchases, and displaying coupons.

There are many reasons why we’ve chosen What gives them an advantage over their competitors, is the possibility to replace a battery and get custom beacons at a reasonable price. In terms of security and reliability, is the best in class.

Finally, the proximity data gave Carrefour an invaluable sample of data on where their customers travel throughout the store and in what order, helping improve what the store offers and where to further increase the store’s profitability and opportunity to build customer loyalty. The success and numbers not only went beyond anything the retailer could’ve dreamed up, they showcased the difference between a proximity-enabled application and one without.
