A wall-mounted self-service kiosk is a self-service terminal that can provide services to users without the need for human assistance. It is typically installed on a wall and uses a touchscreen or other interactive interface to allow users to access various services, such as:

Self-payment: Enabling users to make online payments, pay bills, and perform other transactions.

Information lookup: Providing product information, business hours, location navigation, and other query functions.

Self-service: Allowing users to apply for and book various services, such as hotel reservations, movie ticket purchases, and more.

Self-printing: Offering document printing, copying, and scanning capabilities.

Wayfinding: Providing navigation services for buildings, venues, and other facilities.

These self-service terminals primarily utilize technologies such as electronic touch screens, fingerprint recognition, and QR code scanning to enable unattended self-service, improving service efficiency and customer experience. They are widely deployed in locations like airports, shopping centers, hospitals, and government facilities that need to provide convenient services to a large number of customers.
