This application is designed to optimize the registration and tracking process for visitors at conferences or exhibitions with booths. Its main function is to scan (or "burn") QR codes assigned to each attendee. By scanning the QR code, the application allows users to select the products or services the person showed interest in at the booth, thus facilitating data collection and subsequent follow-up of contacts generated during the event.

In short, it's a practical tool for booths and exhibitors looking to streamline visitor registration, organize their interests, and improve lead management after the event.
