Check-in terminals are self-service kiosks commonly found in airports and train stations. They allow travelers to check in for their flights or journeys quickly and independently. Users can enter their booking information, select seats, and print boarding passes or tickets without needing assistance from staff. These terminals typically feature touch screens and user-friendly interfaces, making them accessible to a wide range of passengers. Many check-in terminals also offer options for baggage drop-off, allowing travelers to streamline their journey through the airport or train station.
