One of the major issues in modern computing is to make the relationship between users and data easier, as data increasingly circulates in complex forms that are not easily manageable by the average person. Typing long web addresses, searching for information with too many factors (such as unusual names or written in languages other than one's own), or simply dealing with data that requires absolute precision, such as GPS coordinates, can become physically impossible as this information grows in volume and complexity. To overcome these types of problems, digital companies have tried to implement solutions that are not always effective, until the slow spread of QR codes became a de facto standard, offering users a tool of remarkable quality and versatility. A QR code is essentially a barcode, readable through any optical device (including the camera of a smartphone), which allows for encoding a large amount of information: this way, it is possible to allow users to access complex digital data from any support, both digital and paper, such as an airplane ticket, an invoice or a restaurant menu, without obliging them to access a website directly or to type access keys.

The potential of QR codes - in development in Italy but quite advanced abroad - promises to significantly simplify the lives of users, and to revolutionize some sectors permanently, thanks to the possibility of instantaneously transmitting information to digital devices. In this guide, I will give you some general information on the functioning of this technology, and I will explain how to generate QR codes for your personalized purposes. We will also see some practical uses of these codes, to allow you, for example, to integrate them into your activity. I remind you that my guides are only informative: I have no relationship with the applications, services and technologies that I will illustrate, and I cannot therefore guarantee their functioning or security.

To create a QR code, there are several options available. One way is to use a QR code generator website or app, which can be found online. These tools allow you to input the information you want to encode, such as a website URL or contact information, and generate a QR code that can be downloaded and used. Another option is to use a QR code generator software on your PC or Mac, which can also be found online.

Once you have created your QR code, it can be printed or displayed on any medium, such as a business card or a product packaging. To read a QR code, simply open a QR code reader app on your smartphone, and point the camera at the code. The app will then decode the information and take the appropriate action, such as opening a website or adding a contact to your phone.

Overall, QR codes offer a convenient and efficient way to share and access information, and are becoming increasingly popular in various industries. Whether you're a business owner looking to promote your products or a consumer looking to access information quickly and easily, QR codes are a valuable tool to consider.
