How can self-service kiosks work efficiently?

A sleek self-service payment kiosk stands prominently against a soft turquoise background, featuring a tall, white frame that exudes a modern aesthetic. The kiosk's upper section showcases a vibrant touchscreen interface, welcoming users with a friendly "Hello!" along with instructions for payment methods, including a recommendation for WeChat face payment. Below the screen, several functional elements are neatly arranged: a card reader, a scanner for QR codes, and an option for cash, all designed for user convenience. The overall composition highlights its purpose in a clean and minimalistic style, reinforcing a contemporary vibe suited for quick and efficient transactions.
