Abstract Customers want fast checkout systems. Retailers are always searching for ways to improve store checkout systems. This study compared the cashier checkout and the electronic selfcheck out systems. Data for this study were collected by observations of checkout processes at Wal-Mart Super Centers in the Jackson, Mississippi, area. Formulated research questions were statistically tested employing the independent samples t-tests and the chi square test for independence. Results of these analyses showed that consumers preferred the cashier
checkout system to the electronic self-checkout system, although shoppers also want to learn how to use the new self-checkout technology. Further studies were suggested on methods of introducing new Point of Sale technology to consumers, and ways to help managers compare costs of checkout systems.
Dedication This dissertation is dedicated in memory of my late parents Chief Phillip Opara-Nadi and Chief/Mrs. Helen A. Opara-Nadi.
