Payment Terminal and RS485 Control Unit System

Cashless Payments with Direct Device Control

Our payment terminal allows you to accept cashless payments and directly control devices such as vending machines, doors, or industrial systems.

Once a payment is completed, the terminal communicates with your control unit via RS485 and instantly activates the configured relay or MDB command.

The system is designed to be easy to integrate, stable in operation, and flexible across different use cases.
