With the growing sophistication of public terminals such as cash machines, information systems and ticket purchasing points, it is important that these machines are easy to use by disabled and elderly persons, as well as foreign visitors.

Terminal should be positioned to avoid glare from lighting and sunlight. The location should also allow easy access by wheelchair users.
						The choice of typeface can significantly affect legibility, particularly for users with low vision.
	Parallax can cause problems for either tall users or persons in a wheelchair interacting from a lower position, especially when screens are at an angle. One solution is a variable height terminal.
							Touch screens should have large fields to help persons with poor manual dexterity.
								Smart cards can store special instructions, e.g. telling the terminal to display large type, deliver speech output or the preferred language of the user.
		Feedback can be enhanced by using illumination, sound in the form of 'beeps' or 'clicks' or tactile feedback which lets the user feel that a button has been activated.
				Features such as a notch for walking sticks will help many elderly or disabled persons.
