 The Data Matrix symbology is probably the most common 2D Matrix. It allows for the highest density of data per module, especially for small symbols, so data matrix grading is essential. The finder pattern consists of solid left and bottom sides which form an “L” pattern, and a horizontal and vertical clock track on opposite sides of the “L”. The clock track tells the number of modules in the matrix and is used to decode the grid on which the modules are placed.There is no version information encoded explicitly within the Data Matrix symbology; all the information about the symbol size, encoding, and error correction is determined from the size of the matrix. |

| Type | 2D Matrix |
| Character Set | All ASCII characters and binary data, using several efficient modes of encoding and data compression. |
| Example of Application Standards | MIL-STD 130, GS1-Data Matrix, Turkish Health Ministry, France CIP13, Postage Franking |
| Non-standardized applications | Asset tracking, serial and part numbers, out-sert matching |
| Key features | Finder pattern consists of L pattern on 2 sides and alternating pattern of clocking information on other 2 sides. Reed Solomon error correction. Sizes ranging from 8×8 to 48×48 are common for square symbols and a few rectangular symbol sizes exist. |

The most common verification standard and data matrix test is ISO 15415. However, for direct part marking applications, AIM-DPM is often used for Data Matrix grading. Choose from any of Webscan’s 2D Data Matrix verifiers or learn more about UID verifiers.
