Have you ever encountered a square code filled with white and black squares? Codes with encrypted content speed up work, for example, for cashiers in a supermarket. 🛍️ Today we will focus on QR codes. Their purpose is to quickly display content, such as a website address. 💪
What is a QR code?
The full English name is Quick Response, and it means fast response. A QR code takes the form of a square filled with light and dark modules that carry information. 🤩 Each small square corresponds to zeros and ones, and with their help, any content can be encoded. The number of modules depends on the amount of information we want to save. The code can contain letters, numbers, and symbols. 😍
The aforementioned solution is used to encode characters in such a way that they can be read very quickly. This small black and white square is most often found in various types of advertisements and newspapers. 📰 It is also placed on product labels, company business cards, or as a link to a restaurant menu. 🥗 With its help, we can quickly open a link without having to manually enter the address.
