What are QR Codes?

What are QR Codes?

QR codes have a rather high-tech background – Toyota used them in its manufacturing process to scan automotive components. From there, QR codes have gradually spread all over the world, now they can even be seen on fashion catwalks. This transition demonstrates the popularity of technologies, but not always their usefulness.

In fact, a QR code is a simple cipher into which information is encoded. Any data can be hidden in this two-dimensional barcode: detailed characteristics of a product, phone numbers and address of a person or company, a link to a website, etc. In total, encrypted information containing 7089 numbers or 4296 letters can be found in a small square.

What is a QR code for? First of all, it’s convenient. Let’s say you were given a standard business card, the information from which will have to be transferred to your gadget manually. However, if there is the same barcode on the card, it is enough to read it with a special virtual scanner, and the data can be saved in the device automatically.

That is, a QR code allows, on the one hand, to fit a significant amount of information into a small image, on the other hand, it opens up the possibility for gadgets to automatically read data and dispose of them in accordance with their nature.

QR codes convey URLs (links to sites) very well. You can easily create such a code yourself, as well as read it using the functions already built into the camera app on many smartphones.

Some say that QR codes are pampering, while others find this way of transmitting information useful. After all, QR codes are a tool, and if you think about it, they can be used in a fun and rewarding way even in everyday life at home.
