About this Barcode...

The QR barcode is a 2-dimensional barcode used for commercial tracking and convenience-oriented applications aimed at mobile phone users (known as "mobile tagging").

QR codes storing addresses and URLs may appear in magazines, on signs, buses, business cards, or other objects... Users with a camera phone equipped with the correct reader application can scan the QR code to display text, contact information, connect to a wireless network, or open a web page in the phone's browser.

QR codes have the following structure:


General Parameters

Additional Parameters

Specific Parameters

Minimum Symbol Size

Choose the number of cells to use for your barcode (in the format “horizontal cells x vertical cells”).

Note: If the number of cells you choose for your symbol is too small to encode the data you entered in Code, Dynamic Barcodes will use a bigger symbol size automatically.
Error Correction

Error correction adds check sums to the barcode to detect and correct incorrect data. You can choose one of the following Error correction levels:

  • Level L: 7% of codewords can be restored.
  • Level M: 15% of codewords can be restored.
  • Level Q: 25% of codewords can be restored.
  • Level H: 30% of codewords can be restored.
Note: Keep in mind that a higher correction level makes the barcode bigger (as more check sums are added to the barcode) and may limit the maximum length of the encoded data.
Width / Height

The Width and Height parameters depend on the Cell Size and the number of cells used for the symbol (Minimum Symbol Size).

For example, a symbol of 25 x 25 cells where each cell is 2 mm gives a Width and Height of 50 x 50 mm.
