What is the primary purpose of data sharing control in mDL usage?

The primary purpose of data sharing control in mobile driver's license (mDL) usage is to limit shared information to only what is necessary for a transaction. This practice is vital in ensuring that individuals maintain their privacy and control over their personal information. By sharing only the essential data required for a particular interaction—such as proving age or identity—users can reduce the risk of their private information being exposed unnecessarily.

This approach not only safeguards personal details but also aligns with the growing emphasis on data protection and privacy by allowing users to manage what information is disclosed and to whom. Such a principle encourages responsible use of personal data in a digital environment, which is increasingly important as technology advances and personal information becomes easier to access and share.
