Web-based Demos for MMS Dyna Devices

This page provides an interactive web-based demonstration for MagTek MMS Dyna devices, showing how to communicate with Secure Card Reader Authenticators (SCRA) using multiple interfaces—including WebHID, MQTT, WebSocket (WSS), WebSerial, and WebBLE—for flexible, real-time device integration and testing.

Web-based Demo

Web Demo	Description
WebHID USB Device Demo	This page provides an interactive WebHID demonstration for MMS Dyna devices, enabling direct USB communication using Chromium-based browsers to send commands and receive real-time device responses.
MQTT Device Client	This page provides a local client application that enables MQTT-based communication with MMS devices, acting as a bridge for secure publish/subscribe messaging between browser demos and connected hardware.
MQTT Device Demo	This page provides an interactive demonstration of MQTT messaging with MMS Dyna devices, allowing developers to send and receive device data using a lightweight publish/subscribe communication model.
WSS Device Demo	This page provides a browser-based demonstration of secure WebSocket (WSS) communication with supported MMS devices, enabling persistent, full-duplex, real-time data exchange over a single TCP connection.
WebSerial Device Demo	This page provides an interactive WebSerial demonstration for MMS devices, allowing direct serial communication from a browser to test command transmission and device response handling.
WebBLE Device Demo	This page provides a browser-based demonstration of Bluetooth Low Energy (BLE) communication with MMS devices, enabling wireless connectivity and data exchange using Web Bluetooth APIs.
