Triggering the 3D Touch menu from the Chrome Home Screen icon on an iPhone 6s or iPhone 7 presents the option to "Scan QR Code" with the browser. The same function can also be brought up on the iPad and older iPhones that do not have 3D Touch support, accessible by searching for "QR" in iOS Spotlight.
When invoked, Chrome uses the rear camera of the iPhone, showing a highlighted square in the middle of the frame that the user should line up the QR code within. The same function can be used for scanning barcodes on product packaging, which can then be used to search for the item online.
QR codes are being used more as a form of marketing, with advertisements displaying the square barcode as a means to take potential customers to promotional websites on their mobile devices.
