QR-code size envy

I normally use QR codes to communicate small amounts of information: URLs or phone numbers, typically.

But I discovered today that the spec allows them to be really quite large. This is the biggest I could manage, and I have successfully scanned this from the screen using Optiscan on my iPhone 3GS, but I had to hold the phone very still and make sure the code filled the image.

(You can click it for the same thing at a larger scale)

It defeated the other two apps I have – QR App and QuickMark. But at this scale the resolution of the camera starts to be significant – you don’t get very many pixels per block – so the same apps might work on an iPhone 4.

Can anyone else read it? (Using a camera from the screen, that is..)


I tried with it on my MacBook Pro, with screen brightness set on high, but the Google app (which is quite a nice QR code reader) failed despite repeated attempts on this one.

Just tried QR Reader from TapMedia on the Iphone4. It detects Codes by itself from the Camera feed, that didn’t work. The Option to take a Picture from within the Software and let it discover Codes within worked without problems. Maybe the stills camera route works with a 3G/3GS too?

Yes, I can read it using a Galaxy S3

I can read it too on a Galaxy S III. “It is a truth … my little Lizzy.”

Thanks for sharing.

Yes it is readable with build in App in Windows Phone 8 on Nokia Lumia 820

It is a truth universally acknowledged, that a single man in possessionof a good fortune, must be in want of a wife.However little known the feelings or views of such a man may be on hisfirst entering a neighbourhood, this truth is so well fixed in the mindsof the surrounding families, that he is considered the rightful propertyof some one or other of their daughters.”My dear Mr. Bennet,” said his lady to him one day, “have you heard thatNetherfield Park is let at last?”Mr. Bennet replied that he had not.”But it is,” returned she; “for Mrs. Long has just been here, and shetold me all about it.”Mr. Bennet made no answer.”Do you not want to know who has taken it?” cried his wife impatiently.”You want to tell me, and I have no objection to hearing it.”This was invitation enough.”Why, my dear, you must know, Mrs. Long says that Netherfield is takenby a young man of large fortune from the north of England; that he camedown on Monday in a chaise and four to see the place, and was so muchdelighted with it, that he agreed with Mr. Morris immediately; that heis to take possession before Michaelmas, and some of his servants are tobe in the house by the end of next week.””What is his name?””Bingley.””Is he married or single?””Oh! Single, my dear, to be sure! A single man of large fortune; four orfive thousand a year. What a fine thing for our girls!””How so? How can it affect them?””My dear Mr. Bennet,” replied his wife, “how can you be so tiresome! Youmust know that I am thinking of his marrying one of them.””Is that his design in settling here?””Design! Nonsense, how can you talk so! But it is very likely that he_may_ fall in love with one of them, and therefore you must visit him assoon as he comes.””I see no occasion for that. You and the girls may go, or you may sendthem by themselves, which perhaps will be still better, for as you areas handsome as any of them, Mr. Bingley may like you the best of theparty.””My dear, you flatter me. I certainly have had my share of beauty, butI do not pretend to be anything extraordinary now. When a woman has fivegrown-up daughters, she ought to give over thinking of her own beauty.””In such cases, a woman has not often much beauty to think of.””But, my dear, you must indeed go and see Mr. Bingley when he comes intothe neighbourhood.””It is more than I engage for, I assure you.””But consider your daughters. Only think what an establishment it wouldbe for one of them. Sir William and Lady Lucas are determined togo, merely on that account, for in general, you know, they visit nonewcomers. Indeed you must go, for it will be impossible for us tovisit him if you do not.””You are over-scrupulous, surely. I dare say Mr. Bingley will be veryglad to see you; and I will send a few lines by you to assure him of myhearty consent to his marrying whichever he chooses of the girls; thoughI must throw in a good word for my little Lizzy.”
