PART 01 · Concept and Positioning
In hospitals, government halls, stations, shopping malls and other crowded public spaces, "where, how to do, when to open, how much money" is the highest repetition rate. The inquiry machine returns these questions to the terminal, allowing personnel to focus on matters that really require manual judgment.
The touch query all-in-one machine is a self-service information terminal that uses a touch screen as an interactive interface and integrates the display screen, industrial control host, touch module, network communication and metal structural parts. It takes "checking" as its core: users directly retrieve information such as service guide, department location, shift time, floor and brand, fee publicity, etc. on the screen without queuing, manual intervention or login account.
Compared with ordinary displays, the inquiry machine has a complete host and system, which can run inquiry software, dock content management background and accept remote operation and maintenance. Compared with ordinary computers, it adopts metal structure, tempered glass and hidden wiring designed for public places, and is more suitable for the use environment of high-frequency touch and long-term startup.
High-frequency and repeated inquiries are borne by the terminal, and the front desk and guidance staff can focus on complex transactions to relieve the pressure of manual windows.
The content is released centrally by the background, and the information at all points is consistent. Changes in policies, prices and shifts can be updated remotely and synchronously.
Metal structure, tempered glass panel, hidden trace and anti-mistouch design, for high-frequency touch and long-running scenarios.
The same hardware platform can be superimposed according to the project scanning code, card reading, printing, camera and other modules, extending from "query" to "business processing".
PART 02 · Product Boundary
