Barcode is the arrangement of different lines to make a matrix which represents for a particular product or item.

However, with the development of hi-tech devices, barcodes are now readable for devices that can read images such as smartphones with cameras.

There are numerous types of barcode such as Linear barcode and Matrix barcode. Depending on each kind, the number of lines and also their widths,length, and spaces vary differently. But they are all machine-readable.

QR code

QR code, which is short for Quick Response code, is actually a type of barcode. Therefore, QR codes are also readable by machines or hi-tech devices such as smartphones. For each QR code, it is comprised of four standardized encoding modes which are numeric, alphanumeric, byte/binary, and kanji to keep data for stores and business efficiently.

Normally, a QR code is arranged with black squares into a square grid on a white background. The square grid can be read by any image-reading devices. From the patterns which are presented in square grids, data will be extracted to represent for a certain product or even a website account.

The most outstanding difference between these two codes is its appearance. When looking at these codes, it can be easily noticed that barcode is the arrangement of several lines while QR code consists of various squares.


Because a barcode only keeps information in the horizontal direction, a QR code can holds information in both horizontal and vertical directions. Due to this great difference in structure, a QR code can store hundreds of times more data than a barcode.


Since a QR code can store much more data in horizontal and vertical dexists, its error margin is around 7 to 30%. Therefore, the use of QR codes quickly becomes a new trend despite recently being introduced.
