(88) QR Codes: What are the most effective and creative uses of a QR code. Displaying QR Codes on an LED Screen. More and more companies are using LED screens in order to showcase their interactive advertising campaigns. QR codes are often used on these LED display ads, however, its important to consider the limitations of QR code scanability on LED displays. One common error that affects QR code scanability are position detection patterns. The position detection patterns are located in three of the four corners of a QR code, allowing omni-directional, high-speed scanning. However, if the refresh rate of the LED screen is low, the barcode scanner, especially on a smartphone, could capture the picture at an incomplete state, causing the code to be unreadable.
Another all too common problem with displaying QR codes on an LED screen is the module distortion of the QR code. When an LED screen can’t display a high resolution grayscale image, QR code modules blend together, distorting the contrast for the camera of a smartphone. Tags: Five Reasons I Love Using QR Codes in My Classroom. There are so many tools that educators can use to get students interested and engaged in their work.

QR Code - stretched Format Position Testing Usage. Android Ideos and QR-Codes, practical limitations - The Nyaruka Blog. We're a huge fan of the Huawie Ideos phones. They are ridiculously cheap, $100 unlocked, and can be bought over the counter at Safaricom in Kenya or about $120 from NewEgg in the states. That is a crazy pricepoint, totally blowing away any other Android phone and really making J2ME handsets mostly irrelevant as contenders for the kind of ICT4D projects Nyaruka undertakes. Recently we've been working with a client and have been considering using these as a way of managing and tracking inventory. After all, the cheapest barcode scanners are around the same price, and you don't get a built in touch screen, GSM connectivity, GPS and the ability to build the entire application on the device.
That makes the Ideos mighty tempting indeed. One thing we were curious about though is just how well they would perform with high resolution 2D barcodes. Methodology We created and printed 2D bar codes encoding 23, 50, 100, 200, 500 and 1000 characters, then tested them at different sizes. Camera Specs. QR Codes Scanning Distance | qrworld. The invisible bubble of space that constitutes each person territory plays a major role in our social life.
In his book “The Hidden Dimension” Edward T. Hall elaborates on the distance factor role in animal social life and humans as well. It appears that people use the same distance rules when interacting with objects as well and QR codes are not an exception. Many times people mention that they were embarrassed to scan a QR code in certain circumstances, or needed to act strangely in order to scan a code. See and This is when the hidden distance factor enters into the play, a factor that we must be well aware of it if we want a good response for our QR codes. Meaningful distances for humans Four distances are mentioned in Hall book; - The intimate distance – effectively zero distance - The personal distance – this is the distance separating members in a no-contact state.

Posted: November 23rd, 2011 | Author: admin | Filed under: General | No Comments » In my previous post, What Size Should A Printed QR Code Be, I mentioned that it wasn’t the size of the QR code image that determined the minimum size at which a QR code could be scanned, it was actually the size of the modules (the little black squares) that make up the QR code image. If the size of the modules fall below the resolution limit of the camera then the QR code won’t be able to be read by the device. A fundamental part of the way QR codes work is that the more data you put into them, the more rows and columns of modules will be introduced into the QR code to compensate for the increased data load.
Hence, for a QR code image of a certain size (width), the more data it contains, the more rows and columns of modules it has and, logically, the smaller each of the modules then become as a result. The data shown is: Not All QR Code Scanning Apps Are Created Equal » QRStuff.com. Posted: May 1st, 2011 | Author: admin | Filed under: General | No Comments » The reason this post came about was that a few days ago Roger Smolski over at 2D Code posted about Color Card Administrator (CCA) setting up a QR Code Test Suite to determine the accuracy and sophistication of QR code scanning apps.
The test suite presents an array of QR codes containing a variety of data types and is intended to set a benchmark standard of readability and interpretation that all scanning apps should aspire to. Testing begins on 01 May 2011 and is open to all QR code scanning app developers. Apps that pass the test will be given an official CCA seal of quality to indicate that it’s able to properly deal with the various established standards that are currently being used in QR codes.
After reading the article, I thought to myself “about time!” MEMO TO (SOME) APP DEVELOPERS: Just thought I’d drop you a few suggestions on how to give your users a better experience when using your scanning app: QR Code Business Cards - Picking a QR Reader. Which App Opens Up Your Business Card's QR Code the Easiest?

QR Code Business Cards - Picking a QR Reader. QR Code Quality Standards Test. Displayed below are several QR test codes. These test codes will help you verify that your QR code scanner is able to properly interpret the data after it has been scanned in order to provide the end user with the desired experience or information using your QR reader. Not all tests are passable on every QR code scanning platform, so a perfect score should not be expected.
Each platform has certain limitations and each test code attempts to deliberately showcase flaws so you can deal with them directly. This test should be helpful for application developers with their own quality assurance testing as they develop their QR reader application and release new updates. It will also assist critics (those writing app reviews or testing apps for approval in various online stores) by giving them a reliable evaluation tool for testing QR reader quality and reliability. Dynamic QR Codes » QRStuff.com. Posted: August 12th, 2012 | Author: admin | Filed under: General | 5 Comments » A basic fundamental of QR codes is that the pattern of modules in the QR code image is a direct graphical representation of the data it contains. That’s just the way QR codes work and is the essence of the algorithm that creates the QR code image. This has one big downside – changing the data encoded into the QR code has the consequential result of also changing the QR code image which, at first glance, presents a significant problem if the website URL that the QR code links to needs to be changed.
How to update the information in a QR code that’s already been published? We grappled with this dilemma in mid-2008 and figured out that the simplest way to address this problem was to have a short URL actually in the QR code and then provide our users with the ability to change where the short URL then redirected to.

QR Codes: What Smartphones Are Being Used For Scanning? » QRStuff.com. Posted: August 29th, 2011 | Author: admin | Filed under: General | No Comments » The dominance of iPhones over Androids as the most popular QR code scanning device has continued to increase over the past 6 months based on figures from our database of recorded scan events. While the Android was the preferred choice prior to February this year, their share has been decreasing steadily since August last year to the point where last month there were 1.9 scans on an iPhone for every one on an Android.
Both Blackberry and Windows devices are struggling along with just over 10% and well under 5% respectively. Considering the number of Android devices out there compared to iPhones, I’ll leave it up to the marketing guys to explain why the numbers stack up the way they do.
