Generate 2D tracking codes
Data Matrix is an dense 2D barcode standard used to mark small physical items like microchips or automotive components.
Set the data payload, adjust the scale in pixels per module, and set the foreground and background colors. The output renders to a canvas and can be downloaded as a PNG file.
Error correction and quiet zones
Modern Data Matrix codes use the ECC200 standard for Reed-Solomon error correction. This adds redundant mathematical data that allows scanners to reconstruct the payload even if the physical label is scratched or partially printed.
When printing Data Matrix codes for physical use, maintain a “quiet zone” (a blank margin surrounding the code) equal to at least one module width so hardware scanners can identify the finder pattern.
