Google Quick Share simplifies file sharing with secure QR code scanning
The feature first tested back in May last year, is now seeing a wider rollout.
Tapping it further will reveal the QR code alongside the number and types of files that a user wants to send. It eliminates the need to keep searching for contacts or pairing for new devices nearby, as scanning a QR code is a bit easier. Also, the QR code can be read by more than one Android device, which means multiple users nearby can benefit from quickly receiving the original files, which can be a savior in gatherings or at events.
