When I was shopping last week, I noticed a significant difference between the checkout times of Walgreens and Safeway. Both were quick to scan and bag my items, but Walgreens processed my chip-based credit card in seconds, while Safeway took around 10 seconds. This highlights the importance of operational efficiency in retail stores, as proven by a study on 37 US retailers that found those focusing on operational improvements were most successful. Kroger's implementation of hi-tech solutions reduced customer wait times from four minutes to 26 seconds, contributing to its revenue growth. High-speed transactions are necessary for many businesses, including retail, financial, e-commerce, entertainment, transportation, and travel, with Redis customers using the Redise Platform to power these transactions. The Redis team has published a technical white paper on managing high-speed transactions in Redis.
