Don’t look now, but QR codes have begun to creep back. They have different names now—Snap Codes and Spotify Codes and Messenger Codes and Other Things Codes—and a much improved sense of style, but the idea hasn’t changed. Because QR codes, it turns out, were just ahead of their time. They required a world where everyone always had their phone, where all phone had great cameras, and that camera was capable of doing more than just opening websites. Over the last few years, both the underlying technology and the way people use it have caught up to QR codes. Before long, scanning codes will feel as natural as thumbing your fingerprint to unlock your phone. And the rise of QR codes will bring augmented reality into your life in all sorts of previously impossible ways. QR codes aren’t a failure from the past. They’re the future. For real this time.
