There are many ways to share links from Google Chrome to Android. You can copy a URL or share it directly with another application. But it is always good to have more options, and one such option is QR codes.
A QR code is a type of barcode that contains information that can be revealed when scanned by a QR code reader. Can be used to store various information, including URLs.
Open the "Chrome" application in phone or Android tablet and type chrome: // flags in the address bar.
Then, in the search bar on the "Chrome Flags" page, enter "Sharing Hub". Change the "Chrome Sharing Hub" flag from "Default" to "Enabled".
Before restarting Chrome, type "QR Code" in search box. Change the flag "Chrome Share QRCodes" to "Enabled".
Now click "Relaunch" to apply the changes.
The "Share Sheet" will appear from below part of the screen. There will be a "QR Code" option at the top of the sheet. Press it.
The QR code will be created and displayed on your screen. You can now allow users to scan or click "Download" to save the QR code in device and use it elsewhere.
You will also notice that there is a "Scan" tab at the top of this screen. This method also works as an easy one way to open a QR code scanner (except opening the camera of the telephone or tablet your).
The process is complete!
