Banking operations have undergone a paradigm shift as a result of technology. Customers increasingly bank with banks rather than branches. Therefore, bankers must be familiar with both hardware and software applications. To this purpose, the book "Information Technology & Digital Banking" describes not only the different components of Emerging Technologies and Digital Banking, but also leads readers through numerous areas of IT Security and Applications. The textbook for the CAIIB optional course "Information Technology & Digital Banking" is this book. The book's content has been divided into the following four modules: Introduction to Information Technology, Module A Systems and Design in Module B Module C: Digital Banking and Banking Technology Applications Information System Security, Controls, and Audit, Module D.
