Campus Video Payphone Client Let kids and parents "meet" anytime
A campus family-call terminal app built on the WeChat Mini Program Hardware Framework (WMPF), deployed on campus phone devices. Students simply touch the screen to make WeChat video calls with parents — no phone needed, no SIM card required.
Product Features
This app is a client program running on campus phones (Android terminal devices), serving as the runtime container for WeChat Mini Programs, providing students with simple and secure video calling services.
Two-Way Video Call
Students call parents from the device, and parents receive a WeChat call popup. Parents can also call back to the device via the Mini Program. Full HD two-way audio/video.
Family Whitelist
Each student can only call authorized parent WeChat accounts, blocking unknown callers. Parents must explicitly authorize the device on WeChat to accept calls.
Plug & Play
The device auto-registers and activates after powering on and connecting to the network. Students select a contact and dial with one tap — no phone number login needed.
WeChat Strong Reminder
Calls reach parents via WeChat's official call notification, the same experience as a WeChat voice call. Won't be buried in messages, ensuring high answer rates.
Auto Logout for Shared Devices
Automatically clears session state and returns to the standby screen after each call, protecting student privacy — ideal for shared-use scenarios like dormitories.
Device Status Management
Built-in network management and self-check. Supports WiFi / 4G connectivity with automatic reconnection on failure, ensuring long-term stable operation.
