Talk:1237: QR Code

It might be a pun on Quick Response Code --109.91.114.82 10:25, 12 July 2013 (UTC)

It's not a pun, it's a widely used abbreviation 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". --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?--69.140.11.243 11:05, 12 July 2013 (UTC)

No it's possible. With the right Emacs command and a Delorean 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? -- 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. 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). --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. 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. --DanB (talk) 12:32, 13 July 2013 (UTC)

It's not that easy, an image is just an image. We would need a tag like <barcode-image>, maybe available at HTML 6.--Dgbrt (talk) 13:36, 13 July 2013 (UTC)

What about using mirrors? That'd be doable. 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.--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".--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 Bump. --Tepples (talk) 00:35, 13 July 2013 (UTC)
