Key findings

Preliminary remark: this app is primarily aimed at drivers and thus at people who are physically and mentally fit to drive. Because of blindness, impaired vision or other physical impairment, a person may be unfit to drive or even temporarily unfit to drive. Nevertheless, we have tested all aspects of accessibility. From our point of view, scenarios are also conceivable with this app, where, for example, a passenger with a restriction might want to find out about parking options or to process parking fee payments.
People with disabilities encounter numerous barriers with the Parkingpay app: in order to adjust the parking time, users must move their finger in a circle at the rotary switch. There is no alternative input method, such as manually entering a start and end time or a duration. The keyboard focus is not visible, so the app cannot be operated with alternative input devices such as a keyboard. The app is only available in portrait format and the text size does not adjust when zooming. For various content, the contrast ratios are not sufficient. The semantic identification of elements has a number of shortcomings: for example, headings are only visually recognisable as such and switches are not marked as switches. Likewise, the receipts in PDF format do not contain any semantic structures and therefore are not accessible. The conditions for accessibility for screen readers and other technical aids are not met across the board.
