− | {{W|QR code}}s | + | {{W|QR code}}s are a type of 2D barcode that can be scanned using any of several apps on a smartphone. This comic illustrates installation of a new application that requires the smartphone to scan a QR code on its own screen. There is no conceivable purpose for such a step, so it would be completely silly. Even with two mirrors or a front-facing camera and mirror, most smartphones would be unable to simultaneously display the camera feed for the QR scanner and the QR code itself. |

The QR code is identical to the previous one. So, if scanned again, it would be an "infinite loop" without any purpose. |
