2.8 Ensure privacy and security during use

Terminals should be designed in a way that reduces the chance of sensitive personal information being perceived by other people in the vicinity. The installation of the terminal should minimise the risk to personal security.


Terminals may provide sensitive private information which the user will not want anyone else to know. However, users with perceptual impairments may require the information to be more easily perceived by themselves. They may also have less ability to detect whether other people can perceive it. As far as possible, being easier for the user to perceive should not mean that sensitive information is also easier for others to perceive.

Many users, particularly older people, are deterred from using terminals like cash dispensers due to worries about personal security.

Directions and Techniques

Do not output the user's PIN

The user's PIN should never be displayed, broadcast or printed.

Provide for audio output via a headset which disables external loudspeakers

If audio output is provided through external loudspeakers, users can be given the option of connecting a headset via a standard mini jack socket. Plugging a jack plug into the socket should then disable the loudspeakers.

Provide good illumination around the terminal

General illumination in the vicinity of the terminal should be good enough provide personal security. Illumination at floor level should be at least 50 lux so that users can easily locate dropped objects.
