Error Prevention (Legal, Financial, Data) - Success Criterion 3.3.4 (Level AA)

Question

Do you provide a way for users to reverse a submission, correct input errors, or confirm their input before final submission of legal commitments, financial transactions, or user-controlled data?

Why is this important?

By allowing a user to reverse a submission, correct input errors, or confirm data before final submission helps them avoid irreversible consequences. This is particularly important for people with disabilities that impact their ability to read, type, or process information correctly.

Whom does it benefit?

Example 1

As a person with a fine motor impairment who tends to make errors when typing,
I want to view a confirmation response
so that I can ensure my information is correct before I submit it.

Example 2

As a person with a math disability who struggles with transposing numbers,
I want to be able to view and edit my shopping cart before purchasing a textbook
so that I can review my banking information before finalizing a purchase.

What should you do?

Ensure your site or application enable users to review their input and reverse their submissions of legal commitments, financial transactions, or user-controlled data before they are final.

How do you do it?

Allow navigation that enables users to review all steps included in the data entry process and make changes within those steps.
Provide a summary so that users can verify all data and make changes if needed.
Allow users to cancel or reverse the submission.
