![]() For a quick test, the Zxing Online Decoder can be used to read a Data Matrix here's the decoded result from the code in the "QR vs Data Matrix"-screenshot above. ![]() The specs linked to above contain a reference decoding algorithm for Data Matrix. Easier to style for branding: Colors, dot shapes, embedded logos.Established formats and usage patterns for encoding URLs, email addresses and similar content.Much better support for scanning with smartphone cameras (readily available developer components and libraries).Of course, symbol size and space requirements are only one aspect when choosing a barcode type QR has several advantages over Data Matrix: We've seen above that Data Matrix is very compact, compare to a QR code with identical data ("1234567890") and module size (1mm): The keyboard layout setting of the scanner does not match the locale setting in your computer.The Data Matrix symbology is deactivated in the scanner.Your scanner if the scan result is different or if the code doesn't scan at all.Ĭommon problems when scanning Data Matrix with non-ASCII data: This code has been verified to scan properly on Mac and Windows PCs. The relevant standard is ISO/IEC 16022-2006 and can be obtained fromĭata Matrix can directly encode accented and diacritic characters like german umlauts. Data Matrix Specificationsĭata Matrix is standardized. Retail (as Data Matrix GS1) and for postage as a replacement for stamps. Other applications of Data Matrix include healtcare (as HIBC and PZN), manufacturing and logistics, Note: Check your scanner if inverted codes are supported before using such codes in production. Such a code can be seen to the lower left of the former two codes. Data Matrix can also be created inverted (or "negative"), with light dots on a dark background. The image shows Data Matrix codes on two chips near the top of the PCB. Here's an example, the PCB from an Apple Watch 7, note fingers for scale ( source): The compact size (at least with small amounts of data) makes Data Matrix a popular choice for the tagging and labelling of small parts, like electronic components or jewellery. Aztec or QR) and is therefore a very compact code, see below for a comparison. The code supports square and rectangular layouts the square versions need less space and are the preferred forms of the code.ĭata Matrix has no distinct finder patterns like other 2D barcodes (e.g. Several versions of Data Matrix exist the only version relevant today is Data Matrix ECC200. Data Matrix (also "Datamatrix") is a two-dimensional or matrix code that can encode up to 3,000 characters.
