27 Jul 2018 --- Brazilian dairy producer Languiru has achieved a six percent spike in milk sales thanks to a promotion pilot which allows consumers to scan QR codes via their smartphones to unlock coupons and prizes. Each milk carton, including chocolate milk (Chocolan), is printed with a unique QR code accessible by a SIG-developed app, enabling Languiru to reward customer loyalty and better understand the behavior of consumers. The SIG technology has proved popular, with more than 12,000 codes generated every hour.
