QR codes for onsite registration can offer several advantages for both you and your attendees, such as faster and smoother check-in, less errors and fraud, more data and insights, and more sustainability and innovation. QR codes can be scanned in seconds to display the necessary information on the screen. This reduces the time and hassle of verifying the attendee's identity and ticket, as well as eliminates the risk of losing, forgetting, or duplicating the tickets. Additionally, they are linked to the attendee's personal data and can be validated by the app or software. QR codes also provide valuable data and insights about your attendees, such as their attendance rate, session preferences, feedback, and engagement. Furthermore, they reduce the need for printing and distributing paper tickets, which can save costs and resources while reducing your environmental impact. Ultimately, using QR codes for onsite registration can make your event more efficient, secure, and data-driven while improving the attendee experience and engagement.
