15 Second QR-code for ultra dummies

QR Code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside the industry due to its fast readability and large storage capacity compared to standard UPC barcodes. The code consists of black modules (square dots) arranged in a square pattern on a white background. The information encoded can be made up of four standardized kinds (“modes”) of data (numeric, alphanumeric, byte/binary, Kanji), or through supported extensions, virtually any kind of data.[1]


Who invented QR Codes?

Invented in Japan by the Toyota subsidiary Denso Wave in 1994 to track vehicles during the manufacturing process, the QR Code is one of the most popular types of two-dimensional barcodes.[2] It was designed to allow its contents to be decoded at high speed.[3]

Unlike the old bar code that was designed to be mechanically scanned by a narrow beam of light, the QR code is detected as a 2-dimensional digital image by a semiconductor image sensor and is then digitally analyzed by a programmed processor. The processor locates the three distinctive squares at the corners of the image, and normalizes image size, orientation, and angle of viewing. The small dots are then converted to binary numbers and validity checked with an error-correcting code.


The use of QR Codes is free of any license. The QR Code is clearly defined and published as an ISO standard.

Denso Wave owns the patent rights on QR Codes, but has chosen not to exercise them.[4] In the USA, the granted QR Code patent is US 5726435, and in Japan JP 2938338. The European Patent Office granted patent “EPO 0672994”. to Denso Wave, which was then validated into French, British and German patents, all of which are still in force as of November 2011.

The word QR Code itself is a registered trademark of Denso Wave Incorporated.[24]In UK, the trademark is registered as E921775, the word “QR Code”, with a filing date of 03/09/1998.[25] The UK version of the trademark is based on the Kabushiki Kaisha Denso (DENSO CORPORATION) trademark, filed as Trademark 000921775, the word “QR Code”, on 03/09/1998 and registered on 6/12/1999 with the European Union OHIM (Office for Harmonization in the Internal Market).[26] The US Trademark for the word “QR Code” is Trademark 2435991 and was filed on 29/09/1998 with an amended registration date of 13/03/2001, assigned to Denso Corporation.[27]

The word QR CODE is a separate trademark assigned to King Estate Winery Limited, US trademark 85293411.[28]


Example ofMicro QR

Micro QR Code is a smaller version of the QR Code standard for applications with less ability to handle large scans. There are different forms of Micro QR Codes as well. The highest of these can hold 35 numeric characters.

Standard QR Code is the QR code standard for applications that possess the ability to handle large scans. A standard QR Code can contain up to 7,089 characters, though not all QR readers can accept that much data.

Custom or artistic QR codes are standard QR codes that have been modified for aesthetic purposes or to make it easier for people to recognize a brand. Many companies use different design techniques to help their code stand out among the crowd. These techniques include: adding color, shapes and various techniques such as round or pointed edges.


Malicious QR Codes combined with a permissive reader can put a computer’s contents and user’s privacy at risk. This practice is known as “attagging”, a portmanteau of “attack tagging.”[29] They are easily created and may be affixed over legitimate QR Codes.[30] On a smartphone, the reader’s many permissions may allow use of the camera, full internet access, read/write contact data, GPS, read browser history, read/write local storage, and global system changes.[31][32][33]

Risks include linking to dangerous websites with browser exploits, enabling the microphone/camera/GPS and then streaming those feeds to a remote server, analysis of sensitive data (passwords, files, contacts, transactions),[34] and sending email/SMS/IM messages or DDOS packets as part of a botnet, corrupting privacy settings, stealing identity,[35] and even containing malicious logic themselves such as JavaScript[36] or a virus.[37][38] These actions may occur in the background while the user only sees the reader opening a seemingly harmless webpage.[39] In Russia, a malicious QR Code caused phones that scanned it to send premium texts at a fee of USD$6 each.[29]

    thanks for replacing the content.

    my issue is you lifted “ALL” of the content and worst of all you purposely didn’t hyperlink back to my site eg you included the url to http://www.Cognation.net/QR but removed the hyperlink so it wouldn’t spider/follow.

    very cute about 15 second overview-lol made me chuckle. Have a good weekend.

    Dean, as you can see “your” content has been replaced by wikipedia 🙂

    I hope you got my email.

    Dear Dean,

    Sorry for the late response, i just got back from a business trip to our Kuwait office and did not have time to check my junk mail until I got back early this morning and thus I am responding to your communication.

    As per your request, I will delete your content from http://www.bloganubis.com today, Friday the 15th, 2012.

    On a personal note, I do not fattom the reason for your anger or threats, bloganubis is a not-for-profit blog on integrated marketing communication which regulrly receives requests to publish editorial content on its pages (which most of the time gets declined), as per the attached screen shot, a live link to your organization website which also identifies it as the source of the content and the article, your name, e-mail, phone numbers in NY, Sydney and London are also mentioned. This was not an attempt to plagirize your work nor to profit from it on the contrary, it was an appreciation of your work and publicity for yourself and your organization, not to mention driving some additional traffic to your website.

    Best regards,

    Excellent summary of the possible outcomes of scanning QR Codes. Now if only smartphone vendors and their software OS partners can get on the same page with pre-installed reader software and best practices for reading contacts from scanned codes.

    For marketers who use codes as a gateway to Web landing pages, a word of caution is in order. Creating the tag, while simple, is only the first step. To successfully build a satisfying mobile Web ‘micro site’ one must contest with tiny screens, less memory and storage capacity, bandwidth limitations and, above all, the absence of run-time applications and (on Apple devices) Flash. Pointing to just any Web site is usually a mistake. Companies like Warbasse Design ( http://www.warbassedesign.com ) — the folks behind the Iron Man 2 campaign — are focused on getting the mobile Web experience right.
