It might be a pun on '''Quick Response''' Code --[[Special:Contributions/109.91.114.82|109.91.114.82]] 10:25, 12 July 2013 (UTC)
: It's not a pun, it's a widely used abbreviation [[User:Hippyjim|Hippyjim]] ([[User talk:Hippyjim|talk]]) 11:25, 12 July 2013 (UTC)
:: I meant that needing to scan it in 12 seconds might be a pun on "Quick Response". --[[Special:Contributions/93.232.203.46|93.232.203.46]] 14:11, 12 July 2013 (UTC)
The only real way would be to screenshot, print, and scan... possible in about 30 seconds. Anyone want to run a time trial?--[[Special:Contributions/69.140.11.243|69.140.11.243]] 11:05, 12 July 2013 (UTC)
: No it's possible. With the right Emacs command and a Delorean [[User:Hippyjim|Hippyjim]] ([[User talk:Hippyjim|talk]]) 11:25, 12 July 2013 (UTC)

:What about simply using other phone or camera to make a photo and display it on its display for the camera of this phone? BTW, why are the phones so stupid they can't display two applications at once? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 11:30, 12 July 2013 (UTC)

You can take a screenshot of your screen (at least in Android) and then read the image with your qr-reading-program. Then it'll display the decoded QR-code, and you'll type it in the app. [[Special:Contributions/189.125.162.182|189.125.162.182]] 14:00, 12 July 2013 (UTC)
:The title text says that additionally the checksum of the camera is checked. So no trick with screenshots would be possible. However I don't see a problem with second camera which displays the photo (as suggested above). --[[User:Chtz|Chtz]] ([[User talk:Chtz|talk]]) 14:05, 12 July 2013 (UTC)

I think that most phones and computers are kind of shoddily programmed, like the developers never take enough time to think of conveniences or solve problems. For example, I should be able to scan QRCs that are on my own screen. [[Special:Contributions/24.98.10.180|24.98.10.180]] 17:29, 12 July 2013 (UTC)
:That's a great idea! Shouldn't a browser be able to interpret them and just make it clickable, like a link? Seems straightforward. --[[User:DanB|DanB]] ([[User talk:DanB|talk]]) 12:32, 13 July 2013 (UTC)

What about using mirrors? That'd be doable. [[Special:Contributions/88.200.105.99|88.200.105.99]] 12:53, 13 July 2013 (UTC)

== Link at Transcript ==

I think the link should be shown at "Explanation". I can't see it at the original comic, so "Transcript" is the wrong section.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 17:11, 12 July 2013 (UTC)
:OK, understood. I just did not try to read that QR code. But the link is still not correct at "Transcript", you have to do some actions to figure out and so it still belongs to "Explanation".--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 18:13, 12 July 2013 (UTC)

== Real-life use for something like this ==

Before I saw the title text, I thought the scenario involved scanning one device's display on another device to set up a key exchange between applications on the two devices, sort of like a [http://bu.mp/ Bump]. --[[User:Tepples|Tepples]] ([[User talk:Tepples|talk]]) 00:35, 13 July 2013 (UTC)
