The QR Code was invented in 1994 by a team led by Masahiro Harada of the Japanese company Denso Wave based on the original marking technology of car parts. It is a two-dimensional matrix barcode that can be used for many purposes.

Later, the encoding and decoding rules of QR Code were formulated into multiple international standards, such as AIM International, JIS X 0510 and ISO/IEC 18004:2015, etc.

The difference between a two-dimensional code and a one-dimensional barcode mainly lies in the encoding method and information capacity. The QR code uses a two-dimensional square matrix, which can store more information and represent more data types. One-dimensional barcodes use one-dimensional lines, can only store a small amount of information, and can only represent numbers or letters. There are other differences between QR codes and 1D barcodes, such as scanning speed, error correction capabilities, compatibility, etc.


QR Code can store more information because it uses a two-dimensional square matrix instead of one-dimensional lines. One-dimensional barcodes can usually store only a few dozen characters, while QR Code can store thousands of characters.

QR Code can represent more data types, such as numbers, letters, binary, Chinese characters, etc. One-dimensional barcodes can usually only represent numbers or letters.

QR Code can be scanned and recognized faster because it has four orientation marks and can be scanned from any angle. 1D barcodes usually need to be scanned from a specific orientation.

QR Code is more resistant to damage and interference because it has error correction features that allow partial recovery of lost or obfuscated data. 1D barcodes generally do not have such functionality.
