A QR code (abbreviated from Quick Response code) is a specific matrix barcode (or two-dimensional code) that is machine readable and designed to be read by smartphones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, a URL, or other data.

Common in Japan, where it was created by Toyota subsidiary Denso Wave in 1994, it is one of the most popular types of two-dimensional barcodes. The QR code was designed to allow its contents to be decoded at high speed.

The technology has seen frequent use in Japan and South Korea; the United Kingdom is the seventh-largest national consumer of QR codes.

Quick Response codes (QR codes) and other two-dimensional codes are expected to achieve widespread use this year – and for good reason. Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.

QR Codes 101
If you’re not yet familiar with QR codes, they’re similar to the barcodes used by retailers to track inventory and price products at the point of sale. The key difference between the two is the amount of data they can hold or share.

Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.

When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.

Any of these desired functions are easily achieved by properly creating your QR code.  It’s a simple process of entering the appropriate data into the QR code generator, described below, and it all takes just a few minutes.

The ability of QR codes to connect people with each other and to multimedia digital content is very useful for businesses and consumers alike.

The Origins of QR CodesWhile QR codes are still considered a novelty here in the United States, they’ve been actively used for over a decade in Japan where they were invented.  QR is a registered trademark of Denso Wave, a subsidiary of Toyota.  Denso Wave has elected not to exercise their patent rights of QR codes and that has encouraged their widespread use.

There are other software companies that have created 2D codes that work much like QR codes, with Microsoft being the most notable.  Microsoft developed their own proprietary software to create codes known as MS tags.  Unlike QR codes, which can be read by a number of different readers, MS tags can only be read by the Microsoft Tag Reader.

Choosing to use QR codes or MS tags is a personal choice.  It seems that MS tags presently allow for more possibilities for creative graphic designs, such as incorporating images and logos into the tag. 

How QR Codes WorkQR code Generators – There are a number of sites for generating QR codes and they’re all free.  An Internet search for QR code generator will offer many choices.

One that has worked well for me is Kaywa, a site created by Datamatrix, which is another pioneer of 2D codes.  You can use it to create QR codes that link to a web page, text, phone numbers, or SMS.  Another with even greater capabilities, including customizing the color and format of your codes is Kerem Erkan.

QR code Readers – The QR code reader app that works well on my iPhone is i-nigma, which claims to be the most widely used reader in the world.  It accommodates virtually any type of camera phone. For the android, you can also try Barcode Scanner. If you already own the popular price-checking app Red Laser, they’ve recently adapted their technology to accommodate QR code reading.

Applications for QR Codes
Sharing – There’s no limit to how, or even how much, you can share with QR codes.  While a video or landing page is easily shared, you could go further and share an entire eBook and even multiple pieces of content that share a common link.

Community – Sharing is how you build community, and one of the favorite arenas for doing this is Facebook.  You can use Likify to create a QR code that links your mobile device to a fully functioning LIKE button for your Facebook page.

Calls to Action – After building a community, the next logical step is to mobilize them to take action.   What are you trying to accomplish?  You can alternate special offers by simply linking your QR codes to new landing pages, and you can combine then with email opt-ins to build your list.

The QR code above takes visitors to a Facebook page welcome tab where the calls to action are Liking the page and a list opt-in.

SEO and SMO – Earlier this month I wrote an article on social graphs where I discuss how web objects such as images, music clips, and videos add valuable content to your social graph.  QR codes enhance both your search engine and social media optimization.  Now you can increase traffic to those searchable objects to further optimize them by encouraging more sharing.

Social Proof – To help build a community offline, it can be helpful to use your vibrant online communities as social proof of your influence and expertise.  As one example, you can use QR codes to link to specific blog posts that have earned an abundance of activity.

Analytics - QR codes most commonly link to urls, which is why link shortening services bit.ly and goo.gl now automatically generate a QR code for sharing your shortened links.  Using goo.gl as an example, you simply click on the “more” link after you create your shortened link, where you are taken to a page that not only gives you the QR code, but useful analytics.

MyQR.co is another site that provides analytics and the ability to customize the color of your QR codes

Practical ExamplesUnited Airlines – Many of the major airlines are now using 2D codes as digital boarding passes.  I recently learned that by the end of 2011 all carriers will be required to provide this service for international flights.

Google Places – When you register your local business with Google Places, you’ll receive a decal for your place of business that includes a QR code to your company website. Be sure that QR code links to the most relevant information that potential customers are interested in – such as hours of operation and current specials and offers.

The Future of QR Codes and TagsThe potential for QR Codes is limitless.  What’s most exciting is how they take what social media is doing well now, bringing people together with technology, and extending it to enhance the experience.

The next generation of barcodes will hold even more information – so much that an Internet connection will not even be necessary.  The content will be effectively embedded in the code.  Imagine scanning a digital code to manifest physical reality?

Content Complied from Jeff Korhan

The spotlight is now on social media buttons that can be integrated into your website or blog. These buttons help visitors share the content on your site with friends, family and colleagues. As webmasters begin to unearth the hidden potential of social media and its use for business promotion, more and more websites are displaying such buttons.

A website must be developed to compete against the best in business; it needs to cover all bases and make sure that it uses every marketing tool available at its disposal, to promote its information and products and services.  Social share buttons have emerged as a new tool in the intensely competitive world of online promotion.

A one-click shortcut

As a website owner, you might wonder as to why integrate a social share button. If visitors want to share your content or link with somebody, they can always logon to Facebook, Twitter etc and do it. Why have buttons on your website? Yes, your website visitor can do this, but they won’t. Why would they waste time and effort in going through the whole process, after all, you aren’t paying them for it, are you? What social media buttons do, is that they offer a ‘shortcut’ for your visitors. All they need to do is click on a particular button, and they are done. They wouldn’t mind doing that.

Impact your marketing efforts

You want your website content to be seen by the maximum number of people. And for this to happen, you are using numerous online marketing tools and techniques. Using social media buttons will make your marketing efforts even more worthwhile. You will give relevance to your site content, by enabling users to share it across various social networking sites. If you get your buttons and content right, there is a good chance that your social media button will leave the kind of impact that you are looking for.

Promotes a Culture of Engagement

Unlike some of the more overt online branding efforts, integrating social share buttons on your website is a way of branding, but one that is not ‘in your face’. When visitors come across a social media button placed on a particular page, they are given to understand that you want to interact with them at a certain level.  For you, customer engagement is more important than just selling your products and services. This is one way of ensuring that your prospective customers see you as a credible and professional merchant, whose content they wouldn’t mind sharing with the people they know.

A word about the different Social Media Buttons

Some people are consumed by the benefits they see in Facebook and Twitter when it comes to social media buttons. No doubt, these buttons help share content and links, quickly and conveniently, but you must not forget that there are other social media buttons available. Take for example LinkedIn. If you are offering the kind of products and services that are targeting working professionals, this social media button might be better suited for your needs. Stumble Upon, is yet another button that can be used. It’s a popular social media platform, which means your content can be seen by many prospective customers. Google +1 is a recent entrant in the world of social media buttons, and helps people recommend the links and content that interest them.

There are plenty of options available. So, the best way to go about it will be to use a combination of social media buttons, which you think can effectively market your site.
