Tesco is developing a range of exciting new technologies and tech-enabled services: Tesco colleagues are equipped with badge computers that fit in the palm of the hand. Ceiling cameras—a.k.a. broccoli cams—keep an eye on the fresh produce section for timely resupply. Electronic shelf labels could replace price tags. And Tesco is experimenting with an "augmented reality" capability that lets customers view products in 3D on smartphones.
