Extensions for Financial Services (XFS) interface specification Release 3.50 - Part 17: Barcode Reader Device Class Interface - Programmer's Reference

This specification describes the functionality of a Barcode Reader (BCR) Service Provider. It defines the service-specific commands that can be issued to the Service Provider using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions.
Persistent values are maintained through power failures, open sessions, close session and system resets.
This extension to XFS specifications defines the functionality of BCR service.
A Barcode Reader scans barcodes using any scanning technology. The device logic converts light signals or image recognition into application data and transmits it to the host system.
The basic operation of the Barcode Reader is managed using WFSExecute/WFSAsyncExecute functions.
When an application wants to read a barcode, it issues a WFS_CMD_BCR_READ command to prepare the scanner to read any barcode presented to it. When a document is presented to the BCR and a barcode type is recognized, a completion event is received which contains the barcode data that has been read.

Ta specifikacija opisuje funkcionalnost ponudnika storitve za branje črtne kode. Določa ukaze, značilne za določeno storitev, ki jih je mogoče izdati ponudniku storitve s funkcijami WFSGetInfo, WFSAsyncGetInfo, WFSExecute in WFSAsyncExecute.
Stalne vrednosti se vzdržujejo z izpadi električne energije, odprtimi in zaprtimi sejami ter ponastavitvami sistema
Ta razširitev specifikacij razširitev za finančne storitve (XFS) določa funkcionalnost storitve za branje črtne kode.
Naprava za branje črtne kode skenira črtno kodo z uporabo tehnologije za skeniranje. Logika naprave pretvori svetlobne signale ali prepoznavanje slik v aplikacijske podatke in jih prenese v gostiteljski sistem.
Osnovno delovanje naprave za branje črtne kode se upravlja s funkcijami WFSExecute/WFSAsyncExecute.
Ko želi aplikacija prebrati črtno kodo, izda ukaz WFS_CMD_BCR_READ, s čimer je bralnik pripravljen na branje katere koli črtne kode, ki mu je predložena. Ko je napravi za branje črtne kode predložen dokument in le-ta prepozna tip črtne kode, je prejet dogodek o dokončanju, ki vsebuje podatke o prebrani črtni kodi.

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 the 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.
---------------------- Page: 9 ----------------------
SIST CWA 16926-17:2023
CWA 16926-17:2022 (E)

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.

2. Barcode Readers

This specification describes the functionality of a Barcode Reader (BCR) Service Provider. It defines the service-

specific commands that can be issued to the Service Provider using the WFSGetInfo, WFSAsyncGetInfo,

WFSExecute and WFSAsyncExecute functions.

Persistent values are maintained through power failures, open sessions, close session and system resets.

This extension to XFS specifications defines the functionality of BCR service.

A Barcode Reader scans barcodes using any scanning technology. The device logic converts light signals or image

recognition into application data and transmits it to the host system.

The basic operation of the Barcode Reader is managed using WFSExecute/WFSAsyncExecute functions.

When an application wants to read a barcode, it issues a WFS_CMD_BCR_READ command to prepare the scanner

to read any barcode presented to it. When a document is presented to the BCR and a barcode type is recognized, a

completion event is received which contains the barcode data that has been read.
