As e-commerce sweeps the globe, retail stores and other businesses are looking to technology to help them compete in the digital age. A supermarket in Tokyo's neighboring Chiba Prefecture has introduced smart shopping carts that allow shoppers to ring up items as they shop. This system not only increases efficiency by letting shoppers avoid checkout lines, a built-in AI system analyzes their shopping behavior and makes suggestions to improve their shopping experience. Retail isn't the only field where technology is changing how business is done. A Tokyo-based IT venture has come up with a fun and unique way to carry out meetings for sales, marketing and customer service-based businesses -- by using a digital avatar. The system also uses AI to analyze client responses in order to improve overall customer service.
