Data Matrix Introduction

Data Matrixis an orientation-independent 2D matrix barcode symbology, composed of black and white modules arranged in either a square or rectangular pattern. With error correction codes added to increase security, Data Matrix can still be read even when damaged. Due to its large capacity of up to 2,335 alphanumeric characters, Data Matrix is widely used in many industries. ECC200 Data Matrix is recommended for new applications by ISO.

OnBarcode provides comprehensive Data Matrix generators and scanner components for Java, .NET, Android, iOS developments and several reporting applications.

The structure of Data Matrix is as below:

When Data Matrix size setting is concerned, two factors are of importance: barcode module width and format mode.

Please get details from Data Matrix size setting instruction.

Data Matrix encodes:

• values 0-127 in accordance with the US national version of ISO/IEC 646;
• value 128-255 in accordance with ISO 8859-1 (referred to as extended ASCII)

Data Matrix barcode includes six encodation schemes, with each encoding:

Data Matrix ECC200 symbol sizes (30 in all) can be divided into two categories:

• 24 square ones with sizes from 10x10 to 144x144 (even values only) not including quiet zones;
• 6 rectangular ones with sizes from 8x18 to 16x48 not including quiet zones;
