Self-service terminals are automated machines that allow users to perform various tasks without the need for assistance from staff. Commonly found in places like airports, banks, and grocery stores, these terminals enable customers to check in for flights, withdraw cash, or scan and pay for items. They are designed to streamline processes and reduce wait times. These terminals typically feature touch screens and user-friendly interfaces, making them accessible to a wide range of people. By using self-service terminals, businesses can improve efficiency and enhance customer satisfaction, as users can complete transactions at their own pace.
