What is a QR code?
QR codes, or Quick Response Codes, are an advanced version of traditional bar codes.
Unlike the latter, which are one-dimensional and contain vertical lines of different widths, QR codes are two-dimensional, made up of small black and white squares forming a larger square.
They can store a considerable amount of information like text, URLs, geographic coordinates, and even Wi-Fi connection information, all accessible via a link to a quick reader with your smartphone.
The ease of access thanks to the information they contain makes them extremely practical in a world in search of speed and efficiency.
History of QR codes
QR codes were created in 1994 by the Japanese company Denso Wave, which was looking for a fast and efficient way to track automotive parts during manufacturing.
Since then, QR codes have evolved far beyond the automotive industry, finding their place in almost every field imaginable, from marketing to tourism, health and education.
Why use the QR Code?
