1. Introduction
1.1 Background to Release 3.50

The CEN/XFS Workshop aims to promote a clear and unambiguous specification defining a multi-vendor software

interface to financial peripheral devices. The XFS (eXtensions for Financial Services) specifications are developed

within the CEN (European Committee for Standardization/Information Society Standardization System) Workshop

environment. CEN Workshops aim to arrive at a European consensus on an issue that can be published as a CEN

Workshop Agreement (CWA).

The CEN/XFS Workshop encourages the participation of both banks and vendors in the deliberations required to

create an industry standard. The CEN/XFS Workshop achieves its goals by focused sub-groups working

electronically and meeting quarterly.

Release 3.50 of the XFS specification is based on a C API and is delivered with the continued promise for the

protection of technical investment for existing applications. This release of the specification extends the

functionality and capabilities of the existing devices covered by the specification:

• Addition of E2E security
• PIN Password Entry
1.2 XFS Service-Specific Programming

The service classes are defined by their service-specific commands and the associated data structures, error codes,

messages, etc. These commands are used to request functions that are specific to one or more classes of Service

Providers, but not all of them, and therefore are not included in the common API for basic or administration

functions.

When a service-specific command is common among two or more classes of Service Providers, the syntax of the

command is as similar as possible across all services, since a major objective of XFS is to standardize function

codes and structures for the broadest variety of services. For example, using the WFSExecute function, the

commands to read data from various services are as similar as possible to each other in their syntax and data

structures.

In general, the specific command set for a service class is defined as a superset of the specific capabilities likely to

be provided by the developers of the services of that class; thus any particular device will normally support only a

subset of the defined command set.

There are three cases in which a Service Provider may receive a service-specific command that it does not support:

The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor

implementation of that service does not support it, and the unsupported capability is not considered to be

fundamental to the service. In this case, the Service Provider returns a successful completion, but does no operation.

An example would be a request from an application to turn on a control indicator on a passbook printer; the Service

Provider recognizes the command, but since the passbook printer it is managing does not include that indicator, the

Service Provider does no operation and returns a successful completion to the application.

The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor

implementation of that service does not support it, and the unsupported capability is considered to be fundamental

to the service. In this case, a WFS_ERR_UNSUPP_COMMAND error for Execute commands or

WFS_ERR_UNSUPP_CATEGORY error for Info commands is returned to the calling application. An example

would be a request from an application to a cash dispenser to retract items where the dispenser hardware does not

have that capability; the Service Provider recognizes the command but, since the cash dispenser it is managing is

unable to fulfil the request, returns this error.

The requested capability is not defined for the class of Service Providers by the XFS specification. In this case, a

WFS_ERR_INVALID_COMMAND error for Execute commands or WFS_ERR_INVALID_CATEGORY error

for Info commands is returned to the calling application.

This design allows implementation of applications that can be used with a range of services that provide differing

subsets of the functionalities that are defined for their service class. Applications may use the WFSGetInfo and

WFSAsyncGetInfo commands to inquire about the capabilities of the service they are about to use, and modify

their behavior accordingly, or they may use functions and then deal with error returns to make decisions as to how

to use the service.

CWA 16926-67:2023 (E)
2. Depository Unit

This specification describes the functionality of the services provided by the Depository (DEP) services under XFS,

by defining the service-specific commands that can be issued, using the WFSGetInfo, WFSAsyncGetInfo,

WFSExecute and WFSAsyncExecute functions.

A Depository is used for the acceptance and deposit of media into the device or terminal. There are two main types

of depository: an envelope depository for the deposit of media in envelopes and a night safe depository for the

deposit of bags containing bulk media.

An envelope depository accepts media, prints on the media and deposits the media into a holding container or bin.

Some envelope depositories offer the capability to dispense an envelope to the customer at the start of a transaction.

The customer takes this envelope, fills in the deposit media, possibly inscribes it and puts it into the deposit slot.

The envelope is then accepted, printed and transported into a deposit container.

The envelope dispense mechanism may be part of the envelope depository device mechanism with the same

entry/exit slot or it may be a separate mechanism with separate entry/exit slot.

Envelopes dispensed and not taken by the customer can be retracted back into the device. When the dispenser is a

separate mechanism the envelope is retracted back into the dispenser container. When the dispenser is a common

mechanism the envelope is retracted into the depository container.

A night safe depository normally only logs the deposit of a bag and does not print on the media.

WFS_DEP_DEVONLINE The device is online (i.e. powered on and
operable).
WFS_DEP_DEVOFFLINE The device is off-line (e.g. the operator has
taken the device offline by turning a switch).
WFS_DEP_DEVPOWEROFF The device is powered off or physically not
connected.
WFS_DEP_DEVNODEVICE There is no device intended to be there; e.g.
this type of self service machine does not
contain such a device or it is internally not
configured.
WFS_DEP_DEVHWERROR The device is inoperable due to a hardware
error. The device is present but a hardware
fault prevents it from being used.
WFS_DEP_DEVUSERERROR The device is present but a person is
preventing proper operation. The application
should suspend the device operation or
remove the device from service until the
Service Provider generates a device state
change event indicating the condition of the
device has changed, i.e. the error is removed
or a permanent error condition has occurred.
WFS_DEP_DEVBUSY The device is busy and not able to process an
Execute command at this time.
WFS_DEP_DEVFRAUDATTEMPT The device is present but is inoperable
because it has detected a fraud attempt.
WFS_DEP_DEVPOTENTIALFRAUD The device has detected a potential fraud
attempt and is capable of remaining in
service. In this case the application should
make the decision as to whether to take the
device offline.
