QR code (quick response code)

A QR code (quick response code) is a type of 2D bar code that is used to provide easy access to information through a smartphone.

Example of a QR code

In this process, known as mobile tagging, the smartphone’s owner points the phone at a QR code and opens a barcode reader app which works in conjunction with the phone’s camera. The reader interprets the code, which typically contains a call to action such as an invitation to download a mobile application, a link to view a video or an SMS message inviting the viewer to respond to a poll. The phone’s owner can choose to act upon the call to action or click cancel and ignore the invitation.

Static QR codes, the most common type, are used to disseminate information to the general public. They are often displayed in advertising materials in the environment (such as billboards and posters), on television and in newspapers and magazines. The code’s creator can track information about the number of times a code was scanned and its associated action taken, along with the times of scans and the operating system of the devices that scanned it.

Dynamic QR codes (sometimes referred to as unique QR codes) offer more functionality. The owner can edit the code at any time and can target a specific individual for personalized marketing. Such codes can track more specific information, including the scanners names and email address, how many times they scanned the code and, in conjunction with tracking codes on a website, conversion rates.

The technology for QR codes was developed by Densa-Wave, a Toyota subsidiary. The codes were originally used for tracking inventory.

Here are a few examples of QR codes in current use:

  • QR codes on business cards link to the individual's full resume or website.
  • A Starbucks promotion featured a QR code-enabled scavenger hunt involving hints accessed through QR codes in the stores.
  • Quiring Monuments in Seattle puts QR code on gravestones to connects people to an online obituary or a website about the deceased.
  • In Florida, the J.N. "Ding" Darling National Wildlife Refuge puts QR codes on signs to connect people to informational videos about wildlife along the trails.

QR Code does have pretty wide applications nowadays. Normally, it is able to insert a qr code into web page by using the image tag or qr code font. However, the best way to add qr code creation function into a web page or site is of use a qr code server control, like this one, http://www.avapose.com/aspnet_barcode/qrcode_generator.shtml. It renders qr code symbol in images on a page.

Another strategy about qrcode : metaqrcode (http://www.metaqrcode.com).
The idea is pretty simple :

1. you put your xml into a server (using REST API)
2. the server produce a qrcode that you can use as you like
3. the qrcode contains an URL
4. following that URL you will have back your XML

This approach permits :

1. no limit on data you put in the XML
2. reading metadata in XML or in json format
3. having a server repository for all your metadata
4. many others...
