In recent years, technology has become increasingly important to the evolution of bank retail delivery systems and the development of new electronic retail products. The ability to deliver new advanced technology products reliably has become a central theme in the marketing strategies of a growing number of banks. Most institutions see introducing new products and services such as PC (personal computer) banking as a necessary step for retaining highly valued customers, and for positioning themselves strategically for the future. As this trend continues, the nature and magnitude of risks posed by technology will continue to change, and these changes will pose significant challenges for banks and banking supervisors.
