QR Code

   Posted by: Grumelo   in web


Wikipedia has a nice description:
A QR code is a specific matrix bar code (or two-dimensional code), readable by dedicated QR bar code readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data.


On TV, on paper even on radio you always have references to web sites.
Currently only the main page of the web site is shown everywhere it makes sense.
If you have an advertisement about a product, it’s not possible to provide a direct web link to its dedicated page on the web because the URL (web link) will be too long, no chance the customer will remember it.
QR code is solving this problem.

QR code can be

  • GPS position
  • visit card
  • web link
  • free text

With QR codes, customers can have direct link to

  • a product description
  • an event details
  • a company web site
  • an online newsletter
  • a contact full address
  • a promotion, a discount, a special offer


You just need to scan the code with your smart phone and a bar code reader application.
In few second you will have a link you can click on, or a new contact in your contact list.


There are bar codes absolutely everywhere. In addition to them you can also have QR code

  • on your visit card
    • a scan and the contact is in your contact list.
  • on door of every shops
    • website of the shop; full address details,  hours
  • on fliers
    • contact information, dedicated web page related to the event or product
  • on printed documents
  • on any products
  • in your email signature


As soon as marketing people will understand the power of QR code, you will see them absolutely everywhere.
Mobile devices with bar code reader are already more than common.

Why isn’t everyone using QR codes?

Google has a good API for generating QR Codes, http://code.google.com/intl/fr/apis/chart/docs/gallery/qr_codes.html.

I recently used it, to set up an numeric archiving system for all our old paper folders, and it rocks. 🙂
