# MPPG/Unigate

This page provides access to an interactive browser-based demonstration for **MPPG/Unigate.** The demos show various use cases with and without using MagTek readers. These demos are designed to help developers quickly test the integration of a physical card reader with the MPPG/Unigate service, validate device communication, and understand the end-to-end flow from device to browser to gateway and back to the device.
