How to make a QR Code?

Origin of QR Codes

How to?

By on 07/31/2013


You are only a few steps away from the creation of your next high resolution QR Code:
 

  • Use the large main form to fill in your text message you want to convert .
  • Choose the ECC mode (The higher the mode is, the better the QRCode is recognizable by smartphones. But keep in mind that the total maximum of allowed characters are reduced. Test it carefully after creating.)
  • Choose a desired size. Personally i choose everytime the maximum to be safe to use the QR Code in every environment.
  • The foreground and background color is optional. Select colors that are full of contrast to make the Code readable. For example: Lightblue and lightgrey is a combination of colors that does not work in most QR Code Scanner.
  • The last and important step is the click on "Generate your QR Code."
  • Choose one of the desired image file formats like PNG, PDF or the EPS format. All of them are scalable to a unlimited and lossless size. (If you need to scale a png lossless, choose in your image manipulation software the scale mode calling something like "rasterize", "pixelize" or "hard edges". For Photoshop it´s "hard edges".)


What is a QRcode?

Origin of QR Codes

Origin of qr codes

The QR code is a brand of a specific two dimensional matrix barcode. It was created by the Toyota branch Denso Wave in 1994 due to the need for tracking automotive parts during the manufacturing processes. The matrix barcode is highly secure designed and can also be reconstructed if up to 30 percent of it has been destroyed.

Use of qr codes

In the meantime, QR codes are well established to present URLs, Telephonnumbers and whole contact data e.g. business cards on websites, image brochures, online and print advertisements. They are used by smart people who recognized that most user do not want to manually write and type any data. If you are looking at a qr code, just take your mobile phone and scan it with an easy click. No need to type anything, the software on your smartphone recognize the content and you will be asked what to do next, e.g. visit a url or safe the data as a new contact.

A maximum of 4,296 alphanumeric characters can be stored within the code.

The encoded text and data is presented in a two dimensional quadrant with black and white dots. A two-dimensional matrix barcodes is able to store approximately 100 times more data than a common linear barcode.
