But due to its quick readability and large storage capacity, this technology has recently become popular beyond the automotive industries.
A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently. The QR code system became popular outside the automotive industry due to its faster readability and greater storage capacity than standard UPC barcodes.
The QR code consists of blocks of 4by2 which are connected to each other by error connection, numbers are set in these blocks. We count the number on which there are black blocks. For example if 1 4 7 and 3 is black. So 1+4+7+3=15 means 15 in this number. Or assume fullstop. It means that black block means dot.

This label is then scanned by the cashier and the description and price of the goods are automatically displayed on the screen. This is called barcode.
how barcode works
The computer understands only binary language, it is in the form of 0 and 1, so 95 fields of barcode are divided into 0 and 1 only. After this these 95 mines are also divided into 15 different mines. In this, the barcode is written in 12 fields and the other 3 fields are divided as guards.
Each barcode is read from left to right, with each number being different. An odd number is written on the left side, an even number is written on the right. On this basis the scanner reads the bar code.

The trend of 2D barcodes is increasing rapidly because we can easily scan these barcodes even with a smartphone.
