Instead of relying on a single PIN or password, you can get a unique QR code that can be turned off at any time. According to the team, the idea is to replace the traditional lock and key system with a more advanced and accessible system via smartphone.
Users can generate QR codes using the desktop or mobile app. They can then send the digital key to the person who needs access to the lock. In addition, the QR scanner reads and identifies codes that trigger the unlock mechanism when an event is registered in the database. This allows the person you want to be given access and track this activity.
The project of the system is in this link.
