Ubiquitous computing provides access to information and computing resources for the users in the place where they are, anywhere and anytime. In Ubiquitous Computing, every applications uses Context awareness as the most important properties. In particular, for smart bank, context awareness attempts to bring the best services to the bank customers. Since bank is the place where most of the people have to access the service, Smart Bank aims to provide the best services it can to the bank customer. In this paper, we propose ISBS, an Interactive Smart Bank Simulator system which aims at scheduling and simulating the behavior of an intelligent banking activity. This system aims at understanding the needs of the customers and provides the best service to the customers using an interactive simulation system. In reality it is hard to implement those systems in real time bank systems. Hence a simulation bank environment is used with virtual sensors instead of physical devices. In this research, the smart bank is considered as an environment made up of independent and distributed devices interacting to support customer services. Therefore, by using ISBS, the developer can realize the relationship among virtual device, surrounded environment, its use and bank appliances. © 2012 IEEE.
