A Check-In System is a method used to track the arrival and attendance of individuals at a specific location or event. This system can be implemented in various settings, such as airports, hotels, and conferences, to streamline the process of registering guests or participants. It often involves the use of technology, such as mobile apps or kiosks, to make the check-in process faster and more efficient. These systems typically require users to provide some form of identification, such as a reservation number or a QR code, which is then scanned or entered into the system. By using a Check-In System, organizations can improve their operational efficiency, enhance customer experience, and maintain accurate records of attendance.
