As the NFC-powered Android Beam is coming out, Google needs a replacement. During the weekend, this replacement may have been discovered and it is called "Fast Share".
The crew of 9to5Google managed to activate Fast Share and figured out almost every detail about it, which devices it will work between, the types of topics you can share, and the process of choosing who to share with.
Google's Quick Share will apparently live in the Android sharing menu as with the "Fast Share" item. "Some of the file types to share include pictures / images, as well as text and URLs. Once you've pressed the quick share button, you can choose from nearby devices that have fast sharing, but you'll also be able to give people the desired visibility and maintain a list of those who have provided these credentials, recipients will be able to accept or reject shares, you will see items as a unit name and "connection ID", and all file sharing user interfaces you can expect to be there.
 You can think of it as an Apple AirDrop competitor as it works between Android, Chromebooks and perhaps more devices, such as IPhones.
File Share was discovered in Android Q on a Pixel 3 XL, but because it is a feature of Google Play Services, it must work on other versions of Android.
