## How much data can a Data Matrix hold?

3116 characters

Datamatrix (or Data Matrix) is a high density 2 dimensional barcode that can encode up to 3116 characters from the entire 256 byte ASCII character set.

## How small can a Data Matrix be?

Data Matrix Size Considerations X-dimensions are commonly displayed in “mils” (thousandths of an inch), inches, or millimeters. The minimum acceptable X-dimension for Data Matrix symbol is 19.5 mils, or 0.0195” (0.494 mm).

**What is a Data Matrix module?**

Data Matrix is a two-dimensional matrix barcode, which encodes text or raw data in a pattern of black and white square modules. Usual data size is from a few bytes up to 2 kilobytes. By adding error correction codes (according to the ECC200 standard) the symbols can be read even if they are partially damaged.

### Can phones read data matrix code?

Some smart phone cameras are physically capable of scanning Data Matrix codes; however, many smart phones do not have the functionality built in and will require a third-party app to read the information.

### What is another name of Data Matrix?

They are also called linear barcodes. Just like QR codes, data matrix codes are 2D barcodes. They are usually square in shape and encode information in the form of square black and white dots, forming the so-called timing pattern. It can encode up to 1556 bytes or up to 3116 digits.

**Is a Data Matrix a barcode?**

#### What is the use of Data Matrix?

Data Matrix codes are used in the food industry in autocoding systems to prevent food products being packaged and dated incorrectly. Codes are maintained internally on a food manufacturers database and associated with each unique product, e.g. ingredient variations.

#### How do you read a Data Matrix?

To read Data Matrix codes, camera scanners are primarily used. They will capture the code in two directions, regardless of the orientation. In other words: It doesn’t matter which way the Data Matrix symbol is turned when it’s being scanned.

**What is the minimum Matrix size for a square 2D Data Matrix barcode?**

10 x 10 modules

## What are the types of Data Matrix?

There are two types of the Data Matrix symbology, based on the error checking and correction (ECC) methods they use:

- ECC 200, which uses the Reed-Solomon algorithm.
- ECC 000, ECC 050, ECC 080, ECC 100, and ECC 140 (known collectively as ECC 000-140), which use convolutional error correction.
