WCAG 2.1 – Criterion 3.3.4 – Error prevention (Legal, Financial, Data)(Level AA)

Have you ever made a mistake that could have cost you not only a lot of nerves but also hard-earned money? The writer knows such cases 😀 Dodano: The principle is that web content creators should provide the necessary help to the user.

What does this have to do with WCAG principles?

There is a criterion in the set that helps prevent such situations – WCAG 3.3.4 Error Prevention (Legal, Financial, Data) at level AA.

How can we help users by applying this criterion?

• Before submitting a form, ask the user an extra question to confirm their data (e.g., through a pop-up modal window).
• Include a special checkbox that the user must check – “I confirm the accuracy of the above data.”
• When deleting certain data from the system or trash, notify the user that the data will be permanently deleted and make sure they are certain about their action.
• Allow users to cancel a transaction within a certain time (e.g., 24 hours after placing an order in an online store).
• Enable users to correct their data on the site (e.g., bank account number, shipping address, or invoice details).

We know that confirmations can sometimes be frustrating, but they often save our transactions or data. It’s good they exist!
