![]() Scanner and apps that are fully compatible with Data Matrix GS1 will transmit the sequence "]d2" at the beginning of the symbol and replace FNC1 characters within the data with the group separator "GS". Looking at the raw codewords, we see that the FNC1's code of 232 (0xe8) has indeed been recognized correctly. While the content has been scanned correctly, the FNC1 character at the start of the symbol is simply displayed as an unknown character ("?"). Here's the code from above scanned with Google Zxing: not transmitted to the application by the scanner) or displayed as non printable characters. However, the inserted FNC1 characters may either be swallowed (i.e. Since no more data follows, the FNC1 can be omitted.Ĭompare to a Code GS1-128 with the same data content:Īny barcode scanner, imager or scanner app that is compatible with vanilla Data Matrix will also scan Data Matrix GS1. Using a 2D barcode symbology like Aztec or Datamatrix with dedicated support for non-ASCII data might be a better choice. The batch number is actually a variable length field which has to be delimited by a FNC1 codeword. 2019 (AI 17, format YYMMDD) and a batch number (AI 10). The data is comprised of the 14-digit GTIN (AI 01), an expiration date of 25 Nov. Sample Data Matrix GS1 Data Matrix GS1 sample barcode encodes "(01)03453120000011(17)191125(10)ABCD1234" which is the example data used in the GS1 guidelines mentioned above. Additionally, the GS1 standards body has published guidelines for implementing Data Matrix GS1. The relevant base standard is ISO/IEC 16022-2006 and can be obtained from Note that Datamatrix GS1 is usually printed without human readable text.ĭata Matrix GS1 Specifications Data Matrix GS1 is standardized. The parentheses are not encoded into the barcode.ĭata Matrix GS1 is the preferred choice for encoding GS1 data when more than 40 characters are to be encoded or space constraints are an issue see below for a size comparison. As with GS1-128, the AIs are separated with parentheses when entering data, e.g. As such, Data Matrix GS1 is constructed in the same way as its linear counterpart from application identifiers (AI) and data content. Press the button GENERATE DATAMATRIX CODE Download the generated code. It is often used for laser marking to permanently mark products. Based on the Data Matrix ECC 200 specifications, Data Matrix GS1 is the 2D variant of Code GS1-128. Use the data field to enter the numeric or alphanumeric information to be encoded. The data matrix code was developed in the 1980s and is one of the best-known 2D barcodes. ![]()
