This is a complete listing of the NDA accessibility guidelines for public access terminals, in order of priority.
It is designed to support assessment tasks carried out by people in the roles of Planning and Procurement and Testing, Assessment and Quality Assurance.
Minimum accessibility requirements (Priority 1)
Following priority 1 will ensure that the terminal can be used by most people with impaired mobility, vision, hearing, cognition and language understanding.
|1.1 Ensure that all operable parts are reachable by people of all heights and people sitting in a wheelchair or buggy|
|1.2 Ensure that displays are within sight of people of all heights and people sitting in a wheelchair or buggy|
|1.3 Ensure that controls are adequately sized and sufficiently spaced to be operated by people with limited dexterity|
|1.4 Ensure that operation requires minimal strength, grip and wrist twisting|
|1.5 Ensure that the terminal can be operated using only one hand|
|1.6 If using a touchscreen or contact-sensitive controls, do not require that it is touched by a body part|
|1.7 Ensure that users with restricted or no vision can use all functions of the terminal|
|1.8 Ensure that all outputs can be perceived by users with restricted or no vision|
|1.9 Ensure that all outputs can be perceived by users with restricted or no hearing|
|1.10 Use the simplest language possible for instructions, prompts and outputs and, where possible, supplement it with pictorial information or spoken language|
|1.11 If using cards, ensure that the card can be inserted into the card reader in its correct orientation without requiring vision|
|1.12 If using biometric identification, provide an alternative access security mechanism for users who do not possess the required biological characteristic|
|1.13 Do not cause the screen to flash at a frequency of above 2Hz|
|1.14 When installing the terminal, ensure that users can get to it along an unobstructed path and operate it from a stable position|
|1.15 Ensure that an equivalent service is available through an accessible channel for users who cannot use the terminal|
Additional accessibility requirements (Priority 2)
Following priority 2 will make it easier to use and will include more people with cognitive impairments or multiple disabilities.
|2.1 Allow sufficient time to accommodate the slowest users|
|2.2 Provide a way for the user to cancel the whole transaction at any point and retrieve any items they have inserted|
|2.3 Ensure that the user interface and task flow is similar across different functions and remains the same across repeated visits|
|2.4 When deploying more than one version of a terminal, ensure that the user interfaces are similar|
|2.5 Do not require users to remember a fixed supplied PIN|
|2.6 Provide for users with multiple impairments|
|2.7 Provide training or assistance for new users|
|2.8 Ensure privacy and security during use|
