Datamatrix is a two-dimensional matrix barcode consisting of black and white square modules arranged in either a square or rectangular pattern. The encoded information can be text or binary. Typical data storage size is from a few bytes up to 2 kilobytes. The total storage of the encoded data depends on the symbol dimension. Datamatrix barcodes also include error correction codes which increase symbol robustness. This means that a partially damaged Datamatrix barcode can still be successfully and accurately decoded.
Sample Barcode:
Uses Error Correction Code (ECC) to reconstruct damaged barcode symbols
Stores up to 2,218 ASCII characters in one barcode symbol
Chains multiple symbols together to encode up to 33,225 characters
