What does a QR code generated by the mDL app signify?

A QR code generated by the mDL app is designed primarily for verification purposes while ensuring the privacy and security of the user's personal information. When scanned, the QR code facilitates the confirmation of essential details like the individual's identity, age, or driving privileges without revealing sensitive personal identifying information directly. This method enhances security, as it allows the user to prove their identity while minimizing the risk associated with sharing personal data.

In contrast, the other options relate to functions that are not inherent to the purpose of the mDL app's QR code. For instance, while it may seem intuitive that such codes could contain personal information, the design of the mDL is precisely to verify individuals without disclosing that data. Similarly, the QR code does not offer functionality for editing personal information or securing online payments, which are not its intended uses.
