Level of Error Correction and masks pattern. It helps the scanner to identify the types of content such as text, URL, etc. It helps the scanner to identify the reference point for alignment. It separates data from the finder pattern.

The sixth row and column in the QR code are dedicated to the timing pattern. It helps the scanner to identify the position of rows and columns. It is also known as finder patterns or position markers. The white space around the QR code represents the quiet zone. The following table describes each component with their work. The following figure depicts the components of QR code.
These components further divided into small components. There are the two primary components of QR code i.e. The following figure describes the structure of the QR code and its elements.
After that, the data is extracted from the patterns that are stored in horizontal and vertical components of the code. After scanning, it processes the QR code using the Reed-Solomon Error Correction Code until the image interpreted. We scan the QR code through an imaging device such as a camera. The Placing of data bits starts from the bottom right corner and moves in an upward direction and changes the position while reach at the top. Modules are arranged in the row and columns that are called Data Matrix. QR code is made up of modules (black and white squares) that contain the encoded data. The Quick Response system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. These standard encodings modes store data effectively. It uses the following four standardized encoding modes: It is used to store information such as text, webpage, URL, etc. We need not to carry any handheld device for scanning. The advantage of a QR code is that it can be scanned by smartphones. The grid arrangement of the black squares on a white background that can be read by an imaging device is called a QR code.

In this section, we will learn how to generate and read QR code in Java by using the ZXing library. Nowadays, it's being used a lot in every field such as GEO location, on products, vehicle tracking, etc. It contains the matrix of small squares in which information is stored. It is an alternative to bar code or we can say that it is a two-dimensional bar-code. Please see the list below.The QR code is shortened for Quick Response code. You can also recognize many other barcode symbologies.
