10、 (CWA 13449) to a 3.0 specification has been prompted by a series offactors.Initially, there has been a technical imperative to extend the scope of the existing specification of the XFSManager to include new devices, such as the Card Embossing Unit.Similarly, there has also been pressure, through im

11、plementation experience and the advance of the Microsofttechnology, to extend the functionality and capabilities of the existing devices covered by the specification.Finally, it is also clear that our customers and the market are asking for an update to a specification, which isnow over 2 years old.

12、 Increasing market acceptance and the need to meet this demand is driving the Workshoptowards this release.The clear direction of the CEN/ISSS XFS Workshop, therefore, is the delivery of a new Release 3.0specification based on a C API. It will be delivered with the promise of the protection of techn

13、ical investment forexisting applications and the design to safeguard future developments.The CEN/ISSS XFS Workshop gathers suppliers as well as banks and other financial service companies. A listof companies participating in this Workshop and in support of this CWA is available from the CEN/ISSSSecr

14、etariat.This CWA was formally approved by the XFS Workshop meeting on 2000-10-18. The specification iscontinuously reviewed and commented in the CEN/ISSS Workshop on XFS. It is therefore expected that anupdate of the specification will be published in due time as a CWA, superseding this revision 3.0

Introduction1.1 Background to Release 3.0The CEN XFS Workshop is a continuation of the Banking Solution Vendors Council workshop and maintains atechnical commitment to the Win 32

28、API. However, the XFS Workshop has extended the franchise of multivendor software by encouraging the participation of both banks and vendors to take part in the deliberations ofthe creation of an industry standard. This move towards opening the participation beyond the BSVCs originalmembership has b

29、een very succesful with a current membership level of more than 20 companies.The fundamental aims of the XFS Workshop are to promote a clear and unambiguous specification for bothservice providers and application developers. This has been achieved to date by sub groups workingelectronically and quar

30、terly meetings.The move from an XFS 2.0 specification to a 3.0 specification has been prompted by a series of factors. Initially,there has been a technical imperative to extend the scope of the existing specification of the XFS Manager toinclude new devices, such as the Card Embossing Unit.Similarly

31、, there has also been pressure, through implementation experience and the advance of the Microsofttechnology, to extend the functionality and capabilities of the existing devices covered by the specification.Finally, it is also clear that our customers and the market are asking for an update to a sp

32、ecification, which isnow over 2 years old. Increasing market acceptance and the need to meet this demand is driving the Workshoptowards this release.The clear direction of the XFS Workshop, therefore, is the delivery of a new Release 3.0 specification based ona C API. It will be delivered with the p

33、romise of the protection of technical investment for existing applicationsand the design to safeguard future developments.1.2 XFS Service-Specific ProgrammingThe service classes are defined by their service-specific commands and the associated data structures, errorcodes, messages, etc. These comman

34、ds are used to request functions that are specific to one or more classes ofservice providers, but not all of them, and therefore are not included in the common API for basic oradministration functions.When a service-specific command is common among two or more classes of service providers, the synt

35、ax of thecommand is as similar as possible across all services, since a major objective of the Extensions for FinancialServices is to standardize command codes and structures for the broadest variety of services. For example, usingthe WFSExecute function, the commands to read data from various servi

36、ces are as similar as possible to eachother in their syntax and data structures.In general, the specific command set for a service class is defined as the union of the specific capabilities likelyto be provided by the developers of the services of that class; thus any particular device will normally

37、 supportonly a subset of the defined command set.Page 6CWA 14050-12:2000There are three cases in which a service provider may receive a service-specific command that it does notsupport:The requested capability is defined for the class of service providers by the XFS specification, the particularvend

38、or implementation of that service does not support it, and the unsupported capability is not consideredto be fundamental to the service. In this case, the service provider returns a successful completion, but doesno operation. An example would be a request from an application to turn on a control in

39、dicator on apassbook printer; the service provider recognizes the command, but since the passbook printer it ismanaging does not include that indicator, the service provider does no operation and returns a successfulcompletion to the application.The requested capability is defined for the class of s

40、ervice providers by the XFS specification, the particularvendor implementation of that service does not support it, and the unsupported capability is considered to befundamental to the service. In this case, a WFS_UNSUPP_COMMAND error is returned to the callingapplication. An example would be a requ

41、est from an application to a cash dispenser to dispense coins; theservice provider recognizes the command but, since the cash dispenser it is managing dispenses only notes,returns this error.The requested capability is not defined for the class of service providers by the XFS specification. In thisc

42、ase, a WFS_ERR_INVALID_COMMAND error is returned to the calling application.This design allows implementation of applications that can be used with a range of services that providediffering subsets of the functionalities that are defined for their service class. Applications may use theWFSGetInfo an

43、d WFSAsyncGetInfo commands to inquire about the capabilities of the service they are aboutto use, and modify their behavior accordingly, or they may use functions and then deal withWFS_ERR_UNSUPP_COMMAND error returns to make decisions as to how to use the service.Page 7CWA 14050-12:20002. Banking C

44、amerasThis specification describes the functionality of the services provided by the Camera (CAM) services underXFS, by defining the service-specific commands that can be issued, using the WFSGetInfo,WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions.Banking camera systems usually consist of

45、a recorder, a video mixer and one or more cameras. If there areseveral cameras, each camera focuses a special place within the self-service area (eg. the room, the customer orthe cash tray). By using the video mixer it can be decided, which of the cameras should take the next photo.Furthermore data

46、can be given to be inserted in the photo (eg. date, time or bankcode).If there is only one camera that can switch to take photos from different positions, it is presented by the serviceprovider as a set of cameras, one for each of its possible positions.Page 8CWA 14050-12:20003.
