Guest on Cloud

The Predictive QR Code is a patented system of virtual cards that, through the "Guest on Cloud" mobile app, enables secure, digital, and smooth authentication of people, vehicles, and goods. Unlike a static QR code, which can be easily copied and swapped, the Predictive QR Code changes every 500 milliseconds, and its validity expires with each change. To ensure continuous operation, it works even in offline mode, without an internet connection, and can be read by a smartphone, QR code reader, or PC webcam.

This system is highly secure due to encryption, utilizing the unique identification number of the mobile device, and optionally, geolocation. Predictive QR Code supports various innovative applications, such as visitor authentication, multi-factor access control to restricted areas, secure access to PCs and remote servers, presence management for workplace safety, remote site management, worker certification on construction sites, and many other use cases like virtual keys for short-term rentals and event management.

Moreover, the Predictive QR Code expands its field of application as a new logical authentication system, protecting IT systems and networks from unauthorized access, malicious attacks, and data theft. It addresses the need to go beyond traditional password and smart card-based authentication, which are often vulnerable to cloning and cyberattacks. With this approach, the user's personal smartphone becomes an essential part of physical authentication credentials, making it difficult to transfer or misuse, and it can be quickly de-registered in case of loss or theft.

In terms of cybersecurity, the Predictive QR Code allows users to authenticate remotely by scanning the code via a PC webcam instead of using a password. In smart cities, it can be used as a virtual card for subscription-based services like parking, gyms, coworking spaces, and car/bike sharing. The introduction of the PQRCode Wallet app consolidates various subscription services into one app, enhancing the user experience across different operators.

Finally, the Predictive QR Code offers a secure authentication model that uniquely certifies the user's identity without needing an ID document and complies with stringent safety regulations, especially for high-risk sites. It precisely authenticates users, ensuring that only authorized personnel can access restricted areas, perform tasks, log into computers, or open doors.
