Reverse Data Matrix barcode, also commonly known as reverse barcode, is a special form of Data Matrix 2D barcode. Data Matrix code itself is a matrix 2D barcode, composed of many small squares, which stores information in the arrangement and combination of light and dark squares. It has the characteristics of high density, high reliability, readability and anti-counterfeiting. The following is a detailed explanation of reverse Data Matrix barcode:

1. Definition and characteristics

Definition:

Reverse Data Matrix barcode, also known as reverse barcode, means that the light and dark squares in the barcode are opposite to those of traditional Data Matrix barcode, that is, the light squares that originally represent "0" become dark, and the dark squares that originally represent "1" become light.

Features:

Color inversion: Compared with traditional Data Matrix barcode, the color arrangement of reverse barcode is completely opposite.

Difficulty of recognition: Due to color inversion, reverse barcode may not be directly recognized under ordinary scanners, and requires specific scanner settings or algorithm support.

2. Application Scenarios

The application scenarios of reverse Data Matrix barcodes are similar to those of traditional Data Matrix barcodes, but they may appear more often in situations that require special recognition processing, such as:

Special environments: In environments where barcodes are easily damaged or color contrast is limited, such as parts exposed to special environments such as high heat, chemical cleaning agents, and mechanical erosion, reverse barcodes may have better recognition effects.

Specific scanners: Need to be used with specific scanners or scanner settings that can recognize reverse barcodes.

3. Recognition methods

In order to recognize reverse Data Matrix barcodes, the following measures are usually required:

Scanner settings: Use a scanner that supports reverse barcode recognition and set the corresponding scanning mode.

Algorithm support: At the software level, it is necessary to develop or adopt a decoding algorithm that can handle reverse barcodes to ensure the correct reading of barcode information.

XTIOT reverse Data Matrix barcode scanners are particularly suitable for scanning color-inverted anti-counterfeiting codes or product information codes on cigarette boxes.

It is also applicable to medical supplies. In the medical field, it is used to scan reverse Data Matrix barcodes on drugs and medical devices to achieve accurate traceability and management.

In industrial manufacturing, it automatically scans reverse barcodes on production lines or packaging lines to improve production efficiency and accuracy.
