During the December announcement, Google revealed that users can simply select the media file they want to share, tap the QR code and have others scan it to start a secure file transfer. It removes the requirement of adding others as contacts, verifying devices or changing the device's sharing settings.

Following the announcement in December, Google is widely rolling out QR code-based sharing in Quick Share on Android. After tapping the Quick Share target in the system sheet and getting the fullscreen UI, you’ll see a new “Use QR code” option in the Send to nearby devices box.
