Identification card systems - User Interface — Part 3: Key pads

This European Standard covers the ergonomic layout and usability of keypads. The keypad may consist of numeric, command and function keys and alphanumeric characters. On the basis that keypad layout impacts performance (keying speed, and errors), this European Standard aims to:
-   enhance usability;
-   ensure ease of use through consistency;
-   increase customer confidence;
-   reduce customer error;
-   improve operating time;
-   ensure ergonomic data entry.
This European Standard specifies the arrangement, the number and location of numeric, function and command keys, including placement of alphabetic characters on numeric keys. Design requirements and recommendations are also provided.
This standard applies to all identification card systems with a numeric keypad for use by the public for stationary or non-stationary devices. This standard also covers keypads on touch sensitive devices.

Systèmes de cartes d'identification — Interface utilisateur — Partie 3 : Claviers

Le présent document traite de la présentation ergonomique et de la commodité d'utilisation des claviers. Le clavier comporte des touches numériques, de commande et de fonction, ainsi que des caractères alphanumériques. Partant du principe que la présentation du clavier a une incidence sur les performances (vitesse de frappe et erreurs), le présent document a pour but :
-   d'améliorer la commodité d'utilisation ;
-   d'assurer la facilité d'utilisation grâce à la cohérence de la présentation ;
-   d'augmenter l'assurance de l'utilisateur ;
-   de réduire les erreurs de l'utilisateur ;
-   de réduire le temps de fonctionnement ;
-   de garantir une saisie ergonomique des données.
Le présent document spécifie la disposition, le nombre et l'emplacement des touches numériques, des touches de fonction et des touches de commande, y compris l’emplacement des caractères alphabétiques sur les touches numériques. Des exigences et recommandations relatives à la conception sont également données.
Le présent document s’applique à tous les systèmes de cartes d’identification équipés d’un clavier numérique destinés au public pour les dispositifs fixes ou mobiles. Le présent document couvre également les claviers des dispositifs tactiles.

Introduction

Machine readable cards facilitate the provision of a growing variety of services across Europe. The

purpose of the EN 1332 series is to increase the accessibility of these services for the benefit of

consumers. This will be achieved by facilitating the inter-sector and cross-border interoperability of

machine readable cards and to do so with the maximum possible degree of user-friendliness.

The EN 1332 series addresses the needs of the widest possible range of users, for example the aged,

minors, people with disabilities, those with learning difficulties, first time users and those not

conversant with the local language.
The EN 1332 series specifies:

a) design principles for the user interface (including symbols) to be incorporated into the design of

card operated devices, but not the machine operations associated with the selection and delivery of

goods or services ;
b) tactile identifiers incorporated into the design of machine readable cards;
c) standard layout for the keypads of card operated devices;
d) coding of user requirements for people with special needs;
e) tactile markings for differentiating cards by application.

The contents of the EN 1332 series are generically based, not sector specific, and cover card operated

devices. It is recognized that the equipment can also be operated by other means, such as the insertion

of notes and coins, but the scope of this document has been, as indicated, narrowly defined.

Issues relating to such consumer concerns at the man-machine interface as PIN presentation are not

dealt with in the EN 1332 series.

The EN 1332 series has been completed with CEN/TS 15291 – Guidance on design for accessible card-

activated devices. This technical specification provides guidance for the design and location of card

activated devices and the immediate environment to facilitate access for the users.

1 Scope

This document covers the ergonomic layout and usability of keypads. The keypad consists of numeric,

command and function keys and alphanumeric characters. On the basis that keypad layout impacts

performance (keying speed, and errors), this document aims to:
— enhance usability,
— ensure ease of use through consistency,
— increase customer confidence,
— reduce customer error,
— improve operating time,
— ensure ergonomic data entry.

This document specifies the arrangement, the number and location of numeric, function and command

keys, including placement of alphabetic characters on numeric keys. Design requirements and

recommendations are also provided.

This document applies to all identification card systems with a numeric keypad for use by the public for

stationary or non-stationary devices. This document also covers keypads on touch sensitive devices.
