This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1332-1:1999.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, 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 the United Kingdom. ÞÍ ÛÒ ïííîóïæîððç EN 1332-1:2009 (E) 4 Introduction Machine readable cards facilitate the provision of a growing variety of services across Europe. The purpose of this standard is to increase the accessibility of these services for the benefit of all users of the system. 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. EN 1332 addresses the needs of all users, including elderly, people with disabilities, first time users, minors, those not conversant with the local language and/or culture. EN 1332 specifies: a) the design principles for the user interface (including symbols) to be incorporated into 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; e) tactile markings for differentiating cards by application. The contents of EN 1332 are generically based, not sector specific, and cover card-operated devices. 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 standard has been, as indicated, narrowly defined. Issues relating to such consumer concerns at the human-machine interface as PIN presentation are not dealt with in EN 1332. The EN 1332 standard series has been completed with CEN/TS 15291, Identification card system 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. ÞÍ ÛÒ ïííîóïæîððç EN 1332-1:2009 (E) 5 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

These components correspond to Sections 5, 6, 7 and 8 respectively. Figure 1 illustrates the relationship between these components. The contents of the Conformance Testing are derived from the user interface Guidelines, which are in turn driven by the Principles and Goals. Figure 1 Relationship between Goals, Principles, Guidelines and Conformance Testing Note that there is not a 1:1 mapping between Goals and Principles, and Principles and Guidelines. For example, the principle “Consistency” can support most of the Goals. Several Principles can support the same Goal. There can also be a conflict between some Principles e.g. flexibility versus stability and ease of use. 5 Goals of the user interface The card-based systems user interface should be designed so that it is: Easy to learn: Ensure that users can be quickly acquainted with the system in order to be able to use it from initial contact. Easy to use: The system shall be transparent and therefore easy to explore and efficient to use. Easy to remember: The use of the interface shall be easy to remember such that the user is able to return to the system after a period of not using it, without having to re-learn its interface. Error tolerant: The system shall minimise the potential for errors being made, while reducing the severity of errors if they do occur. Fatal errors shall not be possible. Effective: The system shall ensure that the desired result can be achieved with a minimum of effort, and that the user never questions the purpose of any part of the user interface. Satisfying to use: Satisfaction measures the extent to which users are free from discomfort, and their attitudes towards the use of the card operated device. ÞÍ ÛÒ ïííîóïæîððç EN 1332-1:2009 (E) 8 Goals for the design of a card-based system can be illustrated using the model shown in Figure 2. The model shows the interaction between a human and the machine being used. The process is described below: Figure 2 A simple model for human-machine interaction 1) The user perceives information via one or more of the machines output devices. For example, the user hears an audible tone representing progress in the transaction. 2) The cognition box represents the users interpretation of the perceived information. E.g. the user interprets the sound as positive feedback and relates the sound to previous experience meaning wait. 3) The cognition box is followed by an action, which is detected by one of the machines input devices. E.g. the user selects a different touch screen button. This input is then processed by the machine and a new output is created. The model includes the environment as this affects how both the user and machine perform. For example, ambient noise may influence the users ability to detect audible outputs, and rain may prevent a touch screen correctly detecting user input. The design of the machines output devices shall correspond to the users capabilities and limitations. For example, any audible feedback on a product designed for use by the aged must have the correct audio characteristics for it to be heard by someone with reduced hearing ability. Likewise, the input devices must also be appropriately selected. E.g. a user with reduced motor skills must not be made to use a device like a mouse; a touch screen is probably better. The users cognition box relates to the machines processing box; the users mental model of how the machine reacts to inputs depends on both the machines actual behaviour and the users expectations. The user interface shall therefore aim to present the machines behaviour as being simple and understandable, as well as congruent with the users expectations. ÞÍ ÛÒ ïííîóïæîððç EN 1332-1:2009 (E) 9 6 Principles for user interface design 6.1 General The principles below (6.2 - 6.13) have been identified to be important for the design of user interfaces that are accessible to all users. The principles should be applied taking into account user characteristics such as: Attention span; Limits of short-term memory; Sensory abilities (e.g. visually impaired); Learning; Experience; The users' mental model of how the system works. It is important to see all the principles listed below in relation to each other as they are closely interlinked. Adopting just one or two of the principles will not ensure good user interface design. Implementing the principles must also take into account possible conflicts, such as between security and ease of use. For exam
