qr code full name Quick Response Code This is called Quick Response Symbol in Hindi It is a trademark for a type of matrix barcode. The QR code was first developed for the automotive industry. 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.
Similarly, by reading the next block, you know what is written in it. So in this way we can read the information hidden in the QR code from our mobile or any scanner. You can generate QR code both online or offline.

barcode what is it how does it work
A barcode is a way to write statistics or information about a product. This barcode contains complete information about a product such as its price, its quantity, which country made it, in which country it was made, which company made it, etc. Barcode can be read with the help of optical scanner.

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.
There are two types of barcodes
1. Linear Barcode (Linear Barcode) or 1 Dimensional Barcode

Which you have used in many digital payment apps like Paytm, phonepe etc. to be seen. A 2D barcode can store more information than a 1D barcode. It can be easily scanned. The trend of 2D barcodes is increasing rapidly because we can easily scan these barcodes even with a smartphone.
What is Barcode Scanner
bar code scanner a electronic device is. In this, the camera is used to read the code. Light is emitted by the lens of this camera in which the information about the fields of the code is transmitted to the computer. After scanning, the information given in the code is saved in the computer.
