Use Case: The user is creating an account in Trenitalia — Italian app, allowing users to purchase tickets for national and regional trains and local buses.

Problem: During the registration process, the user is offered a choice regarding their marketing preferences and privacy policy. The user has to select one of two closely located radio buttons, which makes it difficult to press the correct one. As a result, the user spends time and effort to complete a basic task — creating an account.

Best practice:

In Omio, users can easily select their preferred option between two radio buttons when completing passenger information. The buttons are spaced adequately to prevent accidental selection, ensuring accurate input.
