Simplify access control

Managing access through paid entry or digital authorization has become an essential part of modern service. Whether you need to unlock a bathroom door after payment, open a locker with a PIN or QR code, or grant access to a controlled area, it’s necessary to connect a digital payment to a physical action. With our solution, supported by Unigate, you can create this connection easily.

This product allows you to link online payment or code validation directly to device control, activating relays or unlocking mechanisms after successful authorization. Designed for straightforward applications that don’t require MDB communication, it offers a flexible and efficient way to enable payment-based access and control.

Compact, Connected, and Reliable

With internet connectivity and simple function control, Unigate w/o MDB offers a reliable way to bring payment functionality to your systems. Our solution can be used to build efficient and user-friendly payment-based systems, including:

  • Paid bathroom or shower access control
  • Locker systems opened by QR code or PIN verification
  • Small service activation after online payment
  • Controlled access to shared tools or facilities

By linking internet-based payments or codes directly to physical control, Unigate w/o MDB bridges the gap between online transactions and on-site functionality. For projects requiring more extensive control capabilities, the Sensor Controller offers a complementary option with multiple outputs and broader functionality.

How it works
Connect the Unigate w/o MDB to the Internet and associate it with MQTT Broker.
The user scans the vending machine's QR code (or similar method) using their web app, which sends back credit information through MQTT Broker to the Unigate w/o MDB.
Immediately after, the Unigate w/o MDB opens the relay to unlock the system.
