GS1 DataMatrix

The GS1 DataMatrix (ISO version ECC 200) is a 2-dimensional (2D) barcode which is mainly used to encode a lot of data in a very small barcode. For reading 2D barcodes, an image-based scanner is required. 
The GS1 DataMatrix is mainly used in the healthcare sector and the FMCG-sector for consumer units of variable weight. 

• Aside from a GTIN, other GS1 identification keys and additional information can also be encoded, such as lot number and expiry date. This information is encoded based on Application Identifiers. 

• Up to 3116 numeric characters and 2335 alphanumeric characters can be encoded.
