This final step prompts the user to confirm that they have successfully completed their input and are ready to submit it. It helps to prevent the user from accidentally submitting a form and also prompts user to check that the data they have entered is accurate. This is particularly important when the form causes data to be updated or deleted and is not reversible (e.g. a banking form or an online shopping cart).
Provide a checkbox that users must select to indicate they have reviewed their form responses and are ready for it to be submitted.
