High Quality Content by WIKIPEDIA articles! Xpeak is an standard for device management, based on XML and platform agnostic, initially focused on financial applications but not restricted to it. It serves the same purpose that other APIs like CEN/XFS and J/XFS but is not restricted to one operating system or language, since it works in a client/server model using XML in a way to homogenise the communication between the application and the device services. It`s flexibility allows different parts of the whole business to be implemented in different languages, having the application and the various devices, some implemented in Java, other in C++ and still others in the device`s firmware.
