Sonarax and Stimshop Win Worldline e-Payments Challenge in Their Category Offering Ultrasonic Cashless Payments and Personalization for Retailers

Sonorax’s joint victory with Stimshop highlights how in-store authentication and cashless payments bring the digital experience to the real world of retail

FRANKFURT, Germany & HAIFA, Israel--()--Sonarax (, the ultrasonic connectivity software technology company, announces that it has won the challenges of “In-store ultrasound mobile payment” and “In-store ultrasound biometric authentication,” at Worldline’s e-Payments Challenge, alongside Stimshop ( The two sound-wave pioneers presented their in-store, ultrasound cashless payment solution, which offers Marketpay, a subsidiary of Carrefour, the opportunity to implement the technology in its supermarkets globally. The companies’ award-winning solution is set to pave the future of user experience in retail, addressing solutions for mobile payments, ID & authentication, and IoT pairing, extending the digital experience into the real world.

The ultrasonic technology optimizes user experience for both cashier and self-checkout payments using ultrasonic waves. Sonarax and Stimshop’s suggested solution would offer consumers in supermarkets the ability to automatically connect their smartphones with the cash register upon approach -- no internet required. While waiting in line, the technology would provide coupons for special offers and loyalty points for long waits. The self-checkout experience would enable a hands-free experience -- all interactions are executed on the kiosk POS. Altogether, the payment method presents a frictionless, uniform, and secure user experience.

All processing is done locally on-device without exposing the user to a third-party provider. The same protocol works on all mobile phones, too, and consumes minimal battery life.

“We are immensely proud of meeting Worldline’s challenges and knowing we can offer MarketPay and other Carrefour subsidiaries the best customer experience in their stores,” says Sonarax CEO Benny Saban. “The goal here is to extend the seamlessness of the digital world into the real world, all while ensuring security and privacy. Ultrasonic waves are the way, and Sonarax is proud to be spearheading the initiative.
