retail news in context, analysis with attitude

CNBC reports that Walmart has “published a slew of patent filings that could reshape the shopping experience as we know it. While there's no guarantee any of these ideas will actually be brought to life, they offer a glimpse into Walmart's vision for the future of retail.

Among the filings were for smart shopping carts, wearable tracking devices (that could track and improve employee productivity), in-store drone assistance, and Blockchain-powered delivery truck fleets.

The story notes that Walmart “has published 1,419 patents since 2009.”
