A payment kiosk is a self-service machine that enables users to make transactions and payments for goods or services independently, without the need for human assistance. Typically equipped with a touch screen interface and various payment options such as credit/debit cards, cash, and digital wallets, payment kiosks offer a convenient and efficient way for customers to complete transactions securely. They are commonly found in retail stores, restaurants, transportation hubs, and other public spaces, providing a seamless payment experience for both businesses and customers.
