Wosa (full name is Windows open system architecture Windows Open System Architecture), is a software architecture proposed under the Windows operating system in Microsoft.
WOSA / XFS is a WOSA-based expansion financial service (Window Open System Architecture / Extensions for Financial Services), which is a software architecture proposed by Microsoft's global financial industry software. It conducts the global financial industry based on the WOSA software architecture. Some corresponding modifications.
With the development of global information technology and the development of personal computers, people tend to purchase the hardware of each computer vendor, then assemble into a complete computer, which avoids purchasing a single manufacturer's hardware, which is not needed to be subject to a separate manufacturer. . As a bank financial peripheral industry (ATM as an example) similar to the personal computer, banks hope to purchase multiple manufacturers of vendors like a personal computer, and then assemble an ATM machine. In this way, the bank's ATM machine will not be subject to a factory. Banks need only one ATM machine to maintain their own equipment, and the whole machine can be maintained by a manufacturer, or can also be specially maintained by the ATM machine. Come to maintain. In the end, there will be more manufacturers or agencies that have not produced all ATMs, and they only sell several hardware in the ATM machine, so that banks have more choices, they will get more and better services. Get a cheaper price, which is the biggest beneficiary of each manufacturer's competition. Therefore, foreign banks now require various manufacturers to connect to each other, thereby form a complete ATM machine.
In order to enable financial peripherals of different vendors into a complete ATM, it is necessary to consider both aspects, on the one hand, the interconnection of hardware, one aspect is the interconnection of software. Since the development of hardware has many years, there are many existing technical specifications that enable different hardware to be physically connected, so hardware interconnects can basically do. However, the development history of software is relatively short for hardware, and there is no ready-made technical specification to enable control software on different hardware to connect each other. In order to deal with software interconnection issues in the financial industry, Microsoft, several large financial external manufacturers and several large banking institutions discussed together, and finally set a software technical specification. As long as any manufacturer's own hardware software driver meets this set of specifications, its hardware can be seamlessly connected to other ATM machines that are equally in line with this set of specifications, without having to do any software changes. At the same time, WOSA also specifies the interface specification between the hardware driver and the program of the ATM upper control process, so that the bank can purchase the ATMC superiors provided by non-vendors, more typical is Kal, it can not sell hardware, only sell software, Provide more choices and more professional software services to banks.
This software technology specification is called WOSA / XFS specification, generally referred to as WOSA / XFS.
Because banks are the biggest beneficiaries of WOSA, financial devices purchased by foreign banks are required to meet WOSA specifications, of which ATM's first requirement must comply with WOSA specifications. Of course, NCR, Diebold and other large ATM vendors have soon caching this need, and they have been thoroughly transformed on the original software, launched their own WOSA-specific ATM software.
In recent years, with the advantages of WOSA, the domestic banks have successively requiring various manufacturers to provide WOSA standard hardware drivers, and foreign manufacturers such as NCR, Diebold are also vigorously promoting its WOSA software to domestic banks. Incrush WOSA's concept, I believe that over time, China's banks will also take the same path of foreign banks, and finally require all financial peripherals to meet WOSA norms.
