Level AA
For Web pages 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:
- Reversible: Submissions are reversible.
- Checked: Data entered by the user is checked for input errors and the user is provided an opportunity to correct them.
- Confirmed: A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.>
Explanationx
When completion of a form causes a legal commitment, triggers a financial transaction, or gives consent for personal data to be updated or changed, the user must be able to review, correct, and confirm that the information they have entered is correct, or they must be able to reverse the decision. This provides safeguards to prevent people with disabilities, and indeed all users, from making avoidable mistakes.
