CheckOut aims to make shopping a tech experience

First, there were mom-and-pop stores and boutiques. Then came malls and, with them, big retail chains. After that, we got the online experience -- where with just a click we can access thousands of products, order them, try them on and send them back if they don't suit us. Americans do over 90 percent of their shopping in physical stores, and the launch of physical stores by online companies, including Amazon and Warby Partner, is one of the latest trends in retail, according to New York data company CB Insights. So startups worldwide are also striving to bring new technologies to stores, to help improve the buying experience and sales.
