PARIS, (BUSINESS WIRE), Nov. 12, 2002–SchlumbergerSema, a business segment of Schlumberger Limited (NYSE: SLB), demonstrated .NET Card, an innovative smart card platform technology that brings smart card security to new market segments for multimedia, Wireless Fidelity (Wi-Fi), digital rights management solutions, next-generation mobile messaging and home entertainment applications. The SchlumbergerSema .NET Card technology enables easy integration with all types of multimedia applications, and complements the company’s existing portfolio of smart card platforms that will serve as the core technology for multimedia network services through various connected devices such as MP3 systems, game boxes, PDA’s, PC’s, cable and satellite TV systems, and, potentially, next generation phones.

The technology platform supports digital rights management for games, music and video. It also facilitates roaming applications, such as multimedia messaging combining sound, text, pictures and small video sequences, as well as email downloads and secure authentication for private networks. The .NET Card platform will allow developers to build quick, easy and secure links between different types of multimedia devices and applications, facilitating the process of authentication and connectivity necessary to support the most sophisticated digital technologies.

The advanced infrastructure behind the .NET Card technology incorporates a service layer designed to enable a range of applications to be automatically downloaded and installed onto the smart card. The platform also has multi-language functionality for maximum flexibility and ease-of-use within the developer community. The platform will allow cross functionality between applications and services developed in any language supported by the .NET framework, including Visual Basic®, .NET, C# and J#. SchlumbergerSema has licensed an ECMA-335 standard named Common Language Infrastructure (CLI) from Hive-Minded as a component for its .NET Card platform.
