CEN/TC 224/WG 6 - User Interface

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.

The purpose of this European Standard is to ensure that card-operated devices are accessible and usable by standardising significant components of the user interface.
This European Standard describes principles and guidelines so that people with the widest range of capabilities can use card-based services in any sector. This includes, but is not limited to, purchase of goods and services, leisure, distribution, identification, banking, telecommunications, mass transport, parking, access control. It also provides recommendations for the operational procedures to be followed when users interact with a card-operated device:
- in order to enter a system;
- whilst using a system;
- leaving a system.
In particular, this European Standard will:
- aid the user's interaction with the system through a consistent user interface when entering, using and leaving card-operated devices;
- promote user confidence in card-based systems in general;
- promote efficient use, security and privacy of card-based systems;
- reduce the occurrence and consequences of error when the user enters, uses or leaves the system;
- enable people with different levels of ability and comprehension (e.g. minors, elderly, visually impaired, foreign language, motor impaired, hearing, etc) and different levels of experience (e.g. first-time users) to use card-based systems;
- improve the learnability of new card-based systems through consistency.

This European Standard defines the data objects to be stored within an integrated circuit(s) card and exchanged in order to enable integrated circuit(s) card accepting terminals to identify specific user interface preferences. The preference information may be used by terminals to configure appropriate methods of communicating with the user during a transaction process.
The European Standard also specifies a mechanism for the retrieval of the user preference information from an integrated circuit(s) card and for the combination of data objects to form particular user profiles, through the assignment of unique tags.
Formats and detailed definitions of single data objects are specified, however, the exact method of storage of data within the integrated circuit(s) card is outside the scope of this European Standard.
This European Standard is applicable to the scenario where the cardholder operates the card accepting equipment (e.g. a cash dispenser, ticket machine, vending machine) and to integrated circuit(s) cards conforming to ISO/IEC 7816-4 and ISO/IEC 7816-6 and personalised to the individual cardholder.

The scenario addressed by this European Standard is one where the cardholder operates the card accepting equipment (e.g. a cash dispenser, ticket machine, vending machine, mass transportation).  
It is assumed that the card is a card conforming to ISO/IEC 7810.
Increasing use is being made of machine readable plastic cards.  However, some potential user groups such as people who are elderly, disabled, blind or visually impaired could have difficulty in using existing card layouts to distinguish between cards with different functions such as a bank, telephone, pre-payment or social security card.
This standard addresses the needs of users who have difficulty reading non-embossed information on plastic cards, including persons with special needs, for example older people, minors, disabled people, visually impaired people, those with learning difficulties, first time users, and those not conversant with the local language.

This document provides guidance for the design and location of card-activated devices and the immediate environment, to facilitate access for the widest possible range of users (all / most members of the community), subject to conditions of adequate privacy and security.
The contents of this document are generically based, not sector specific, and cover 'card-activated device' , the generic term used in this document to encompass:
a)   terminals (device with card reader and other components such as keyboard and displays);
b)   standalone card readers (access control for building, public transport);
c)   hand held devices (e.g. mobile phone when used to access other card-activated devices).
Card-activated devices may be used either by pedestrians or car drivers.
This document may also be applied to devices that are not card-activated, e.g. they may be activated by notes, coins, tickets, tokens, touch or other interaction with the user.
(Context of use includes: unattended, public and home use, handheld).
This document addresses the card-activated device and its immediate vicinity. It does not address the entire building / locality in which the card-activated device is located. (The reader is referred to appropriate ISO, CEN and national standards for guidance on designing accessible built environments. It should be noted that national legislation, standards and guidance have different requirements).
The term 'wheelchair' in this document refers to manually propelled wheelchairs, not power driven ones, which are often of different dimensions in relation to manually propelled wheelchairs.

This European Standard specifies the form, dimensions and location of an edge indentation for a single standard tactile identifier, when applied to ID-1 cards. This edge indentation will appear at the option of the card issuer.

This European Standard defines design principles for card based services that are applicable to any sector (eg banking, telecommunications, mass transport, parking, logical access control, physical access control). It also provides recommendations for the operational procedures to be followed when users interact with a card operated device : - in order to enter a system; - whilst using a system; - leaving a system.

This European Standard specifies the arrangement, the number and location of numeric and command keys. The arrangement of function keys is outside the scope of this European Standard, as are alphanumeric keys. Design requirements and recommendations are given, as are example layouts.

This European Standard defines the data elements to be stored within an integrated circuit(s) card and exchanged in order to enable integrated circuit(s) card accepting terminals to identify specific user interface preferences. The preference information may be used by terminals to configure appropriate methods of communicating with the user during a transaction process.
