I used to dream that QR Codes would be the magical glue that would allow the easy passage of content among digital and analog devices. Want to read a web page on your phone that you’re viewing in your desktop browser? Just snap a picture of a QR Code on the page, and voila! it appears on your mobile device.
The reason for this hope was that it once was hard to move URLs around, unless you used URL shorteners, and even then it often involved careful retyping. Apple got on top of this years ago with Handoff, a set of features that rely on Apple’s Continuity framework—which pulls together Wi-Fi, Bluetooth, and proximity—to let you hand the state of an app off among Macs, iPhones, and iPads, including a web page in Safari while Safari is the active app.
