How QR and barcode scanner apps work
To understand how scanners receive information, you need to understand what a barcode and a QR code represent.
Barcode
A barcode is an alternation of black and white stripes of different thicknesses. Sometimes a black and white sequence of other figures is used. In the linear barcode we are used to, a combination of 4 stripes of varying thickness is encoded into numbers from 0 to 9. There are many types of barcodes, including complex ones, into which you can enter not only numbers, but also the entire English alphabet with some special characters.
The scanner program for Android uses a camera to recognize the barcode on the area of the image that falls within the scanning area. Then it draws a horizontal line along it and extracts the encoded characters. The result obtained is displayed on the display. After which the application sends a request in the form of a combination of numbers to the database, where it finds the desired product.
QR code
Unlike a linear barcode, where only the horizontal bar is the significant coding area, a QR code is a two-dimensional matrix. Visually, it is a square filled with black and white areas, various combinations of which are assembled into meaningful modules. Accordingly, information is recorded along the entire perimeter of the image.
Large squares at the corners of the image are needed for orientation. A simple example: draw a square on a piece of paper, place dots around its perimeter, rotate the drawing and ask another person to determine the original position of the square. This will prove to be very difficult. In this way, the original code image can also be rotated. Marking the squares allows you to determine the correct location of the graphic design.
The QR code scanner for Android recognizes the boundaries of an image, breaks it into modules, and then matches the image with a database. And then, the application operates depending on what was encrypted in the code, as well as on the functionality of the program.
