Two-dimensional code static area related introduction

Before introducing the static (blank) area of a two-dimensional code, let's briefly understand what a two-dimensional code consists of. From the visual point of view, the appearance of the two-dimensional code looks like a small square composed of one by one.

Components of QR code:

1) Location detection markers: The prominent squares located at the three corners of each code provide QR codes that are easier to recognize and facilitate high-speed reading.

2) Alignment marks: These help to streamline the code placed on the surface. It's smaller than the location-detection tag, but it gets bigger the more information the QR code contains.

3) Timing mode: black and white alternating modules configure the data grid to help the scanner calculate the size of the data matrix.

4) Version information: This determines which of the 40 different QR code versions to use, the most common versions being 1 to 7.

5) Format information: This pattern contains information about the data mask pattern and the code's fault tolerance, making it easier to scan.

6) Data and error correction key: The error correction function shares a structural space, which contains all the data in the two-dimensional code. The mechanism of the positive block is essential to allow up to 30% of the code to be read when corrupted.

7) Dead zone: This blank area can be thought of as the boundary of the QR code, helping to improve the understanding of the scan and providing structure. It determines what is part of the code and what is not.
