Smart card-enabled solutions are a solid foundation for information and communications security in enterprises, government agencies and other organizations.  They secure access to PCs and applications, buildings and  rooms.  They unfold their potential for cutting costs primarily by bundling  various security functions (multifunctionability), increasing the level of  security (physical and logical protection) and simplifying authentication  processes (single sign-on, process optimization).  The return on investment  that can be expected from them is high: approximately USD 2.5 million a year at a company with 2,000 employees, according to calculations by Datamonitor.
