The C40 and Text modes have four separate sets. Data Matrix codes, along with other open-source codes such as 1D barcodes can also be read with mobile phones by downloading code specific mobile applications. It specifies the Data Matrix symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters.
After the component enters service, the Data Matrix code can then be read by a reader camera, which decodes the Data Matrix data which can then be used for a number of purposes, such as movement tracking or inventory stock checks.

Error correction codes are often used to increase reliability: Also shown are the end-of-message code marked Endthe uso P and error correction E bytes, ieo four modules of unused space X. In order to make that less likely, the length and data bytes are obscured by adding a pseudorandom value R nwhere n is the position in the byte stream.
Large symbols contain several regions. Ericksen of the U.
The message read ” Hello, World! As more data is encoded in the symbol, the number of cells rows ido columns increases. Therefore this version remains current. For industrial engineering purposes, Data Matrix codes can be marked directly onto components, ensuring that only the intended component is identified with the data-matrix-encoded data. Label artwork is required to allow the 2D Data Ief to be positioned for optimal scanning.
Each varies in the amount of error correction it offers, with ECC offering none, and ECC offering the greatest. For other uses, see Data matrix disambiguation. Data Matrix has an error rate of less than 1 in 10 million characters scanned.
A Data Matrix symbol can store up to 2, alphanumeric characters. For example, dot-peened cells are generally round.

It is desirable to avoid long strings of zeros in the coded message, because they become large blank areas in the Data Matrix symbol, which may cause a scanner to lose synchronization. Graphical symbols for use on information technology and telecommunications technical drawings and in relevant technical product documentation.
