Concerts bring together large crowds in a short period of time, which makes on-site safety a top priority. Millimeter-wave body scanners offer a contact-free way to manage these high volumes efficiently. Each scan takes about two seconds and can identify both metal and non-metal prohibited items, solving the limitations of traditional manual checks that are often slow and may leave blind spots. This approach greatly improves entry speed and screening reliability, helping create a safe environment where performers and audiences can focus entirely on the show.
