Foreword
This Technical Specification (CEN/TS 15291:2006) has been prepared by Technical Committee CEN/TC 224
“Machine-readable cards, related device interfaces and operations”, the secretariat of which is held by
AFNOR.
This Technical Specification is based on the results of a CEN TC 224 WG 6 Project team commissioned to
perform the necessary research.
It is intended that this Technical Specification will complement, but not be a part of, the series EN 1332,
“Identification card systems – Man-machine interface”. The EN 1332 series includes the following parts:
 Part 1: Design principles for the user interface;
 Part 2: Dimensions and location of a tactile identifier for ID-1 cards;
 Part 3: Key pads;
 Part 4: Coding of user requirements for people with special needs;
 Part 5: Raised tactile symbols for differentiation of application on ID-1 cards.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
Introduction
Machine-readable cards facilitate the provision of a growing variety of services across Europe. The purpose of
this document 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.
This document complements the EN 1332 series. EN 1332 addresses the needs of all users, including people
with special needs, not overlooking first time users, minors, those not conversant with the local language.
EN 1332 specifies:
a) the design principles for the user interface (including functions to be represented by symbols) to be
incorporated into the design of card operated equipment, but not the machine operations associated with
the selection and delivery of goods or services;
b) a tactile identifier to be incorporated into the design of machine readable cards;
c) a standard layout for the keypads of card operated equipment;
d) coding of user requirements for people with special needs.
The contents of the EN 1332 series are generically based, not sector specific, and cover card- operated
equipment. It is recognised that the equipment may 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 is dealt with in a
separate standard, see ISO 9564.
The information society is moving from a “service” society to a “self service" society and the key to accessing
many of these services will be via the use of a machine readable card. It is essential that all users are able to
achieve access in order to avoid a two-tier society.
The purpose of this document is to increase the accessibility of these services for the benefit of all
stakeholders and to explain the design requirements for equipment, services and the environment in which
they are used.
According to CEN Guide 6:2002, 3.2, accessible design is focused on principles of extending standard design
to people with some type of performance limitation to maximize the number of potential customers who can
readily use a product, building or service which may be achieved by:
e) designing products, services and environments that are readily usable by most users without any
modification,
f) making products or services adaptable to different users (adapting user interfaces) and
g) having standardized interfaces to be compatible with special products for persons with disabilities.
NOTE 1 Terms such as design for all, barrier-free design, inclusive design and trans-generational design are used
similarly but in different contexts.
NOTE 2 Accessible design is a subset of universal design where products and environments are usable by all people,
to the greatest extent possible, without the need for adaptation or specialized design.
There are a wide range of application areas where card readers might be employed (public, e.g. ATMs and
personal, e.g. mobile phone). This is likely to expand enormously in the future.
This document is written in the form of a set of informative clauses covering various aspects of location,
access, user space, lighting, interface layout and interface design etc., to which compliance is necessary in
order for a device to be regarded as “accessible”, i.e. enables inserting or swiping the card. It should be noted
that all components of the total design are equally important. If one part is missing or inadequate it may not be
possible to use the card-activated device at all.
This document is based on a review of published literature, supplemented by limited research, practice and
expert judgment.
1 Scope
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.

4 General principles for ease of access and use
4.1 Approaches to ease of access and use
There are two fundamental approaches to making solutions accessible and easy to use: one is to design for
the widest possible range of users (universal design); - the other (Assistive Technology) approach is to design
for direct interaction by a limited range of users, supplemented by indirect interaction (e.g. via wireless
communications between card-activated devices and assistive technology) for those unable to manage direct
interaction with card-activated devices.
The underlying principle for ensuring ease of access and use is that systems have to be seen within their
context of use. Requirements for the design of any specific solution are dependent upon the interaction of
people, tasks, systems and the environment in which they will be operating. There is no one single solution
that can cover all eventualities. The reader of this document should bear this in mind when applying the
guidance in this document.
4.2 General principles
The following principles should be observed:
a) The user population and their related anthropometric requirements must be determined before planning
the location of a terminal.
b) Users should be able to approach, enter, find their way around and move in the premises where the card-
activated device is located, and use it with ease.
c) The terminal should be located and designed to provide for privacy and security of the user and their
possessions.
d) Improvements that benefit users with particular impairments should be implemented, even where it is not
possible to make it usable by everyone.
e) The concept of accessible design should be considered at the start of the planning and before the
building process to avoid expensive and complicated conversions.
f) For those who cannot access a card-activated device suitable alternative provisions should be given (e.g.
provide personal service).
g) The card-activated device should have a consistent user interface, especially with regards to the method
of entering, navigating in and exiting the card-activated device (EN 1332-1).
h) The card-activated device should be adaptable to meet a user’s specific requirements, for example, to
provide output (on screen or sound) in a preferred language (EN 1332-4).
i) Installers and designers should consult with target user groups, e.g. national/local support groups, local
users and relevant local associations during the design process and before installation. Consider if target
group might expand or change.
j) The design and location of card-activated devices should take into account the potential consequences of
vandalism.
5 Access and location
5.1 Location site
The choice of a site for the installation of public card-activated devices should take into account factors such
as the layout, structure and location of an existing building, passing trade, security aspects, environmental
noise, and building regulations. These factors may potentially be in conflict with the requirements for
accessible design. A poorly sited device placed in direct sunlight can become unusable because of reflected
glare. In addition, defective or damaged local lighting can mean that users cannot see the interface clearly or
with any sense of security.
If the card-reading device is located inside, entrances and lobbies should be easy to negotiate and well lit.
In addition, the following factors should be considered:
a) The existence of a clear circulation space fronting the area of the proposed installation.
b) The area should be free from obstructions, such as building stanchions, street utilities, etc. in the vicinity
of the card reading device. This will assist wheelchair access and facilitate the queuing of users so that
more privacy can be obtained.
c) The location of card reading devices also affects their security of use. There are various factors to
consider. These may be in conflict with regard to ease of use and accessibility for different user groups.
d) Adequate parking spaces for mobility-impaired people should be available on the shortest possible
accessible route to each card-activated device.
e) The access route to the card-activated device should be free of obstructions, i.e. free from stairs,
thresholds, narrow passages and heavy doors. The surface of the floor space should be level, stable, firm
and non-slip. Snow, ice, standing water, leaves or litter can make the access route difficult or dangerous
for all users and impossible for a wheel chair user.
f) Terminals offering similar services should have a unitary visual/auditory/tactile profile, be placed
according to these guidelines, and be clearly identifiable from both a long and short distance. The
purpose of the terminal should be clear to the user through visual/auditory/tactile means.
5.2 Location signs and visual indications
Signs may be for public information or, if environmental features have impacted on the design of the facility,
for safety. Safety signage should use the appropriate symbol, colour and shape in accordance with current
International Standards to warn users of the potential hazard. Public information signs should conform to the
current International Standard ISO 7010.
The following factors should be considered:
a) Graphical symbols are an essential aid for people with learning difficulties and for people unfamiliar with
the surroundings.
b) Persons with disabilities may have limitations in the movement of their head, or a reduction in peripheral
vision. Signs positioned perpendicular to the path of travel, are the easiest for them to notice. Persons
can generally distinguish signs within an angle of 30° to either side of the center-line of their faces without
moving their heads.
c) Card-activated devices should be clearly signed by means of text and or graphics, using the appropriate
standard symbol where available. Signs should be placed above the card-activated devices.
d) There should be clear and visible markings of the location of the terminal and they should be easily
identifiable at night and on overcast days.
e) Colour and contrast should be used to enable visually impaired persons to locate the terminal.
f) Colour markings should be at least 40 cm wide on the walls and floor surrounding the terminal.
g) Symbols, icons and pictograms should conform to EN 1332-1.
h) Signs should be visible from front and side, or all round if free standing signs shall be clearly visible to
people in both seated and standing positions.
i) In order to help people find their way to accessible card reading devices, signage should be located at
decision-making locations (exterior and/or interior) and, where applicable, should include the appropriate
standardised symbols.
j) All signs should be consistently placed and of uniform design so as to be readily seen.
Detailed information is given in Annex D for the following:
 basic design features for text based signs;
 lighting for signs;
 placement of signs located parallel with front of terminal;
 height of characters in signs including symbols;
 international symbols of access;
 sign maintenance.
5.3 Alternative methods for locating terminals
It is important that terminals can be located by persons with impaired vision. This can be achieved by:
a) The provision of tactile markings on the floor (specially patterned pavements or floor surfacing which can
be easily perceived by blind or partially sighted people) leading the user towards the terminal. Such
surfaces should comply with Annex D.
b) The use of technology such as voice messages or audible direction instructions transmitted to a hand-
held device such that selected audible route guidance could be provided to lead users to the terminal
from their current location.
Access routes can be graphically displayed (in a similar manner to current in-car route navigation systems) on
hand-held device screens within the terminal vicinity, upon request. Ideally, the user’s location on the route
should be indicated as well as the nearest “accessible” route to the terminal from the user’s current location
(see also Clause 14).
Annex D contains more detailed design information on the following:
 tactile signs and symbols;
 detectable tactile floor surfaces for warning and way guidance.
5.4 Lighting
5.4.1 General
Lighting should be designed to provide safe mobility through the provision of good visibility in all ambient
lighting conditions. There should be a consistent pattern and level of light in the absence of natural light.
Lighting should avoid misleading shadows and highlight obstacles such as stairs, curbs, and ramps in the
locale and close to the access route. Care should be taken to ensure that a terminal does not face into direct
sunlight as this can cause direct reflected screen glare or strong shadows which can make the device
unusable.
Maintenance programmes should be in accordance with Clause 17.
5.4.2 Design
Good lighting means:
a) no glare;
b) flicker free light;
c) sufficient intensity of light (see Annex D);
d) sufficient contrast;
e) appropriate direction and distribution of the light;
f) appropriate colour of the light;
g) no emission of heat or UV radiation.
These factors are particularly important for visually impaired, including older people. They often need to read
very close to the text.
5.5 Accessible route
There are a number of factors to take into account when ensuring that the route to the card-activated device is
accessible, such as path gradient, width and height of access route, avoidance of protrusions into path,
avoidance of barriers / hazards. Detailed information is provided in Annex D.
5.6 Space in front of card-activated devices
When designing the area immediately in front of a card reading device, called the “User Operating Space”, the
following factors should be considered:
a) Sufficient space to allow users (especially those in wheelchairs) to choose between making a forward,
parallel (side) or angled approach.
b) Sufficient space in which users can perform any interactive tasks at the reader terminal without being
cramped or forced to adopt stressful postures.
c) Provision of an area at the terminal where the user has control of valuables (e.g. wallet, card) in order to
provide a reasonable level of security.
d) Privacy of information on the screen.
e) Sufficient space for users to easily manoeuvre themselves away from the terminal after use.
f) Sufficient space to accommodate all of the above outside of any circulation or passage space for general
movement of people (e.g. pathways, corridors, street pavements, roadways and so forth).
g) The user operating area should be separate from any line-up or queuing areas.
Annexes C and E, provides dimensions in relation to the wheelchairs and dimensions for wheelchair approach
required by the location of the terminal.
5.7 Vestibules
a) Vestibules should be designed for full accessibility to people in wheelchairs and people who can only
walk with aids. This requires the following considerations to be made:
b) Terminals should be placed at a height where they can easily be used by all users including seated
people, children and people of short and tall stature. The terminal should be height adjustable or several
terminals at different heights should be installed within the vestibule.
c) There should be no steps.
d) The width and design of the vestibule and its doorway should allow entry of a standard manual propelled
wheelchair and adequate space for the users hands. Annex C is referred to for dimensions on
wheelchairs.
e) Doors should be easy to open and close by a seated wheelchair user and not require any great strength
to operate, ideally they should be of sliding automatic type. Non-automatic power assisted doors should
be operated from e.g. a treadle or large touch / kick panel or button that requires little force, to make
access possible for people with little strength and for people who cannot use their arms and hands.
f) The acoustic conditions in the vestibule for communications activities (e.g. public telephone) should not
adversely affect intelligibility or make it easy for other people to overhear conversations.
g) Consideration should be given to providing seating where operations / transactions at a card-activated
device or terminal are prolonged (e.g. public telephones, internet access terminal) particularly where a
two handed operation is required to operate the terminal.
h) Public terminals and terminal booths should be designed so that people who cannot use their arms and
hands are able to access them without enlisting the help of other people.
i) A shelf should be provided that people can use to write on and to provide assistance to people who use
canes, grab bars and guide dogs. They are also useful in other situations e.g. where the person has only
one hand available to perform a transaction, or where the person is carrying bags, briefcase, umbrella,
etc.
Annex D provides information on:
 detailed design information on the location of card-activated devices;
 parcel shelves and Grab bars;
 detailed design information on pavements, floor surfaces, drainage and queuing areas.
6 Location and layout of operating features
6.1 Introduction
The purpose of this clause is to provide principles and information on the location and layout of operating
features so that they are easy to understand and use (in terms of reach, line of sight and viewing distance) by
the widest possible range of users.
6.2 High level design principles
A challenge may exist in trying to accommodate both individuals who are very short, or in wheel chairs and
individuals who are very tall. Performance of different actions, e.g. pushing a button vs fine manipulation may
require different operating heights/ sightlines.
Several strategies for resolving this include:
a) several terminals with different heights;
b) height adjustable terminals/pedestals;
c) variable height adjustable terminals (manual or automatic adjustment via coding on card – EN 1332-4);
d) screens which rotate to present themselves downward or upward;
e) dual screen systems;
f) Hand Held Devices which download the interface and use remote communication;
g) alternative method for providing service;
h) If the only solution is a fixed height installation the following points should be considered:
 If a screen or keyboard is situated on a vertical plane towards the top of the terminal, some shorter
people and wheelchair users may have reduced privacy when operating the terminal.
 If a screen or keyboard is on a vertical plane towards the centre or bottom of the machine, some tall
people may experience difficulties in bending to observe and operate the components.
 Ergonomics design principles should be followed in determining the relationship between the angle and
depth of the keyboard and the height of machine installation.
 When the keyboard is used for entry of secret information, the keying operation should not be visible to
bystanders. In addition to the comfort of the user, the extent to which shielding of the fingertips by the
hand is necessary to provide privacy in keying may be an important factor in determining the height of
installation.
 Duration of the transaction should be taken into account when assessing trade offs.
 Consider provision of seating for transactions that may be lengthy.
Card reading devices may involve the use of a keyboard and the insertion and retrieval of cards, paper and
possibly other items (e.g. coins, tokens). These features need to be located where:
i) they can be easily detected;
j) they can be reached and grasped easily;
k) the necessary operations can be carried out conveniently and efficiently.
The position of each feature in relation to reach range and viewing angles should be based on priority
according to how essential it is and how frequently it is used. It is also useful to consider the sequence of
events which make up the task in order to determine appropriate layouts for features such that they generally
match the sequence of use.
A multi-modal user interface (e.g. manual keyboard and speech input alternative, or visual and audible
displays) may be necessary to provide suitable access to the widest range of users.
6.3 Reach and vision
6.3.1 Layout of operating features
Operating features (including but not limited to controls, card readers, and dispensers) should be within easy /
comfortable reach range of potential users.
a) Ideally terminals should be adaptable to the user’s size, position, characteristics and capabilities (e.g. be
height adjustable, be mounted on flexible arm, include angle adjustment for display screens, etc).
b) Ideally the terminal should adjust automatically according to information stored in the user profile on the
card.
c) Where terminals are not adaptable to suit the user, a wide range of users will be accommodated if the
operating featu
