Since the arrival of Smartphones, QR codes are increasingly present in our lives. This type of code was already around for much longer, but it did not become so famous until then. On occasion we may want to encrypt a text and a good way is to create a QR code. Of course, it will not serve to keep any secret, since anyone with a compatible reader can read it. In this article we will teach you how to create and read QR codes in Ubuntu with GQRCode.
