A barcode is a small image of lines (bars) and spaces that is attached to retail store items, identification cards, and mail to identify a specific product number, person, or location. That code uses a sequence of vertical bars and spaces to represent numbers and other characters.
In the world wide web, you can see a large amount of information about the so-called matrix codes, they are also 2D barcodes. What are they and what are they used for?
2D codes differ from conventional barcodes in that information is recorded in two dimensions at once, which means that the thickness of vertical bars and the distance between them are read in the barcode, while 2D code records information both horizontally and vertically.
Thus, 2-dimensional barcodes allow you to store much more information than the long-familiar barcode. In addition, when the information is encoded in matrix code, information is added to it for recovery, which allows you to read the information encrypted in the code even if the barcode is partially damaged!
The matrix code has several varieties: QR-code; DataMatrix Micro QR. In appearance, they are not much different from each other, but the QR code is most widely used.
We have put together three sites where you can generate your own code for free:
And the new PDF Splitter significantly improves the accuracy of bar code recognition.
