What method does the mDL device use for secure data exchange?

The method that the mDL (mobile driver's license) device uses for secure data exchange is Contactless Secure Exchange. This technology allows for the transmission of data between devices without direct physical contact, utilizing short-range communication protocols. It ensures that sensitive information, such as a driver's license details, is transferred securely and efficiently, reducing the risk of unauthorized access or data interception.

This method provides a convenient and secure way to verify one's identity or confirm the legitimacy of the mDL without the need for manual input or complex pairing processes. The use of contactless technology is particularly important for maintaining user privacy and security while enabling quick exchanges in various scenarios, such as during traffic stops or when entering venues that require age verification.
