The speed of scanning and the ability to be taught from all angles is of great importance in terms of time savings. It is possible to read data matrix codes that are damaged or dirty to a certain extent.

How Does QRcode Work?

QR codes convey information through a graphic code made up of black and white pixels. Where a barcode is one dimensional, the data matrix is two dimensional. The most visually distinct element of the QR code is the square blocks used to guide the code when scanned by the reader.

This allows the code to be scanned in any direction, including upside down, and convey the correct message. These four blocks (three embedded in the corners and one at the bottom right) appear in every code and allow the code to be correctly decoded in any direction.

The format version, bug check version, and decode mask are coded around these blocks. The QR code is surrounded by a white space area called a “quiet zone” that helps the reader find the edges of the code.

QR code is read from the lower right corner. Pixels are read in groups of 8, containing one byte per 8 pixels. While ASCII (character set based on the Latin alphabet) is probably the most common encoding, the specification also includes options for numbers, kanji, and other encodings.

What are the Differences between QR and Barcode?

  • Barcode: One size code.
  • QR code: Two size code.
  • Barcode: To read the barcode, the scanner must be aligned with the code.
  • QR code: It can be read in any direction, it does not need to be aligned.
  • Barcode: No data correction. The barcode needs to be printed correctly.
  • QR code: If there is an error of up to 30%, it can be read.
  • Barcode: The application is very limited for products, books, pin code and can only store numerical data.
  • QR code: As mentioned earlier, it has a wider range of applications.
  • Barcode: Limited storage capacity. It can only store alphanumeric characters.
  • QR code: Relatively large storage capacity. It can store alphanumeric characters, kanji (japanese symbols), binary information.
  • Barcode: Depends on database.
  • QR code: It can be used independently.
