What is a QR Code?

A QR code stands for "Quick Response Code" and is a type of barcode in a square shape, consisting of black and white patterns. Developed in 1994 in Japan for the automotive industry, this technology is now used globally across many different sectors. QR codes can store more information than standard barcodes and can be read both horizontally and vertically. They can be described as advanced barcodes that are scannable by machines. When asking what a QR code is, it's seen as a type of matrix barcode made up of square dots. These dots as a whole direct to the information encoded in the code. This can include product information or promotional material, as well as directing to a payment transaction page, facilitating online payment processes.

How Does a QR Code Work?

QR codes store data using a special algorithm in a matrix arrangement. These codes can be scanned by smartphones and dedicated QR code readers. During the scanning process, the information within the QR code is decoded and presented to the user. This information can include links to websites, text, images, or other digital data.

How Is a QR Code Created?

Creating a QR code can be done through various online tools and applications. Users enter the information they wish to store into these tools, which then convert this information into the QR code format. The generated QR codes can be saved in various formats (e.g., PNG, JPEG) and used in printed or digital materials.

What Are QR Codes Used For?

The question of what to consider when creating a QR code is quite important. Firstly, the code you create should not be smaller than 2 cm. Additionally, as the data and number of characters you input into the code increase, the size of the code should also increase. Paying attention to using black and white colors in your code will facilitate easy scanning, so this point should be considered.
