8.30 WCAG 2.2 Success Criterion 3.3.7 – Redundant Entry

To help users to complete multi-step processes more easily, do not ask for the same information twice in the same process.

Before Rectification  

A e-form keep asking same data in different step.

The example above, applicant required to provide membership no. more than once during application process.

After Rectification  

Same information has only input once and auto-complete by system.

Membership no. input in the first step of the above application process is pre-filled in the 4th step of the same process. Make it easier for users to complete multi-step processes.

A mechanism simply help user reduce the data input redundancy.

Same information only asked once during multi-step processes.
