CEN/XFS

Last updated

CEN/XFS or XFS (extensions for financial services) [1] provides a client-server architecture for financial applications on the Microsoft Windows platform, especially peripheral devices such as EFTPOS terminals and ATMs which are unique to the financial industry. It is an international standard promoted by the European Committee for Standardization (known by the acronym CEN, hence CEN/XFS). The standard is based on the WOSA Extensions for Financial Services or WOSA/XFS developed by Microsoft.

With the move to a more standardized software base, financial institutions have been increasingly interested in the ability to pick and choose the application programs that drive their equipment. XFS provides a common API for accessing and manipulating various financial services devices regardless of the manufacturer.

History

Chronology:

WOSA/XFS changed name to simply XFS when the standard was adopted by the international CEN/ISSS standards body. However, it is most commonly called CEN/XFS by the industry participants.

XFS middleware

While the perceived benefit of XFS is similar to Java's "write once, run anywhere" mantra, often different hardware vendors have different interpretations of the XFS standard. The result of these differences in interpretation means that applications typically use a middleware to even out the differences between various platforms implementation of XFS.

Notable XFS middleware platforms include:

XFS test tools

XFS test tools allow testing of XFS applications and middleware on simulated hardware. Some tools include sophisticated automatic regression testing capabilities.

Providers of XFS test tools include:


J/XFS

J/XFS is an alternative API to CEN/XFS (which is Windows specific) and also to Xpeak (which is Operating System independent, based on XML messages). J/XFS is written in Java with the objective to provide a platform agnostic client-server architecture for financial applications, especially peripheral devices used in the financial industry such as EFTPOS terminals and ATMs.

With the move to a more standardized software base, financial institutions have been increasingly interested in the ability to pick and choose the application programs that drive their equipment. J/XFS provides a common Object Oriented API between a pure Java application and a wide range of financial devices, providing a layer of separation between application and device logic that can be implemented using a native J/XFS API or wrapping an existing implementation in JavaPOS or CEN/XFS.

J/XFS was developed by the companies De La Rue, IBM, NCR, Wincor Nixdorf and Sun Microsystems and is now hosted, monitored and maintained by the European Committee for Standardization, CEN.

Multimedia Home Platform (DVB-MHP) is an open middleware system standard designed by the DVB project for interactive digital television. The MHP enables the reception and execution of interactive, Java-based applications on a TV-set. Interactive TV applications can be delivered over the broadcast channel, together with audio and video streams. These applications can be for example information services, games, interactive voting, e-mail, SMS or shopping. MHP applications can use an additional return channel that has to support IP.

Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment.

In computer science, message queues and mailboxes are software-engineering components typically used for inter-process communication (IPC), or for inter-thread communication within the same process. They use a queue for messaging – the passing of control or of content. Group communication systems provide similar kinds of functionality.

Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.

The Khronos Group, Inc. is an open, non-profit, member-driven consortium of 170 organizations developing, publishing and maintaining royalty-free interoperability standards for 3D graphics, virtual reality, augmented reality, parallel computation, vision acceleration and machine learning. The open standards and associated conformance tests enable software applications and middleware to effectively harness authoring and accelerated playback of dynamic media across a wide variety of platforms and devices. The group is based in Beaverton, Oregon.

Globally Executable MHP (GEM) is a DVB specification of a Java based middleware for TV broadcast receivers, IPTV terminals and Blu-ray players. GEM is an ETSI standard and an ITU "Recommendation”. GEM defines a set of common functionalities which are independent from the signaling and protocols of a specific transmission network and enables to write interoperable Java applications for TV. GEM is not intended to be directly implemented, but rather forms the basis for broader specifications targeting a particular network infrastructure or class of device. GEM defines profiles for different device classes (targets) – these define the set of available features of GEM for this device class. Currently GEM defines targets for broadcast, packaged media (Blu-Ray) and IPTV. Combinations of these targets can be combined into a hybrid GEM platform, which enables to build devices with multiple network interfaces, such as a combined broadcast/IPTV set-top box.

The SCOPE Alliance was a non-profit and influential Network Equipment provider (NEP) industry group aimed at standardizing "carrier-grade" systems for telecom in the Information Age. The SCOPE Alliance was founded in January 2006 by a group of NEP's, including Alcatel, Ericsson, Motorola, NEC, Nokia, and Siemens. In 2007, it added significantly to its membership.

Teller Assist Units (TAU), also known as Automatic Teller Safes (ATS) or Teller Cash Dispensers (TCD), are devices used in retail banking for the disbursement of money at a bank teller wicket or a centralized area. Other areas of application of TAU include the automation of starting and reconciling teller or cashier drawers (tills) in retail, check cashing, payday loan / advance, grocery, and casino operations.

JavaPOS, is a standard for interfacing point of sale (POS) software, written in Java, with the specialized hardware peripherals typically used to create a point-of-sale system. The advantages are reduced POS terminal costs, platform independence, and reduced administrative costs. JavaPOS was based on a Windows POS device driver standard known as OPOS. JavaPOS and OPOS have since been folded into a common UnifiedPOS standard.

<span class="mw-page-title-main">Computer appliance</span> Dedicated computer system

A computer appliance is a computer system with a combination of hardware, software, or firmware that is specifically designed to provide a particular computing resource. Such devices became known as appliances because of the similarity in role or management to a home appliance, which are generally closed and sealed, and are not serviceable by the user or owner. The hardware and software are delivered as an integrated product and may even be pre-configured before delivery to a customer, to provide a turn-key solution for a particular application. Unlike general purpose computers, appliances are generally not designed to allow the customers to change the software and the underlying operating system, or to flexibly reconfigure the hardware.

Xpeak is a 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. Its 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.

Middleware is a type of computer software program that provides services to software applications beyond those available from the operating system. It can be described as "software glue".
