Client object for use in a self-service terminal

A client object for use in a self-service terminal, such as an automated teller machine (ATM), is described. Also described is a system comprising a self service terminal and a service provider server (24), such as a CRM system, operable to communicate or provide services in a format that is incompatible with the client terminal. Between the client terminal (10) and the CRM server (24) is an intermediate processor (22), such as a web server, having an adapter or interface (20) that allows communication between the terminal (10) and the CRM server (24). The interface (20) is configured to pass to the terminal (10) a limited amount of information in a specific protocol. In particular, the interface (20) passes text, such as a word-based advertisement, to the terminal (10), which then assumes sole responsibility for the presentation of that text on a client terminal screen.
