QR codes, these intriguing little squares printed on products, advertisements, and even used for financial transactions, have become an essential part of our digital daily lives.

Originally from Japan in the 90s, they have transcended borders and fields of application, becoming the symbol of a flourishing digital era.

By facilitating our transactions, our connections, and by serving as a bridge between the tangible and the digital world, QR codes (Quick response code in English) are much more than a simple coding tool.

Let's enter the fascinating world of QR codes and discover the magic behind these small black and white squares.

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.
