Where ICT is non-web software that provides a user interface, it shall satisfy the success criterion in Table 11.36.

Table 11.36: Software success criterion: Error prevention (legal, financial, data)

For software that cause legal commitments or financial transactions for the user to occur, that modify or delete user-controllable data in data storage systems, or that submit user test responses, at least one of the following is true:

  1. Reversible: Submissions are reversible.
  2. Checked: Data entered by the user is checked for input errors and the user is provided an opportunity to correct them.
  3. Confirmed: A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.
NOTE: This success criterion is identical to the WCAG 2.0 Success Criterion 3.3.4 Error prevention (legal, financial, data) replacing "web pages" with "software".
