TIM Terminal connect (Worldline / SIX)

This guide describes how to connect a TIM terminal directly to Belbo. TIM (Till Integration Module) is the standard protocol for card terminal integration in Switzerland. It was developed by SIX Payment Services and has been continued under the name Worldline since its acquisition by Worldline (2021). Other Swiss payment providers with ep2 terminals also support the TIM protocol.

In Belbo this option is called "TIM/SIX". In Belbo Satellite the connection appears as "Worldline Terminal".



Prerequisites

Before you set up the connection, ensure that the following requirements are met. Most of these are configured by your terminal provider during setup – if in doubt, ask them.

  • You are using Belbo on a computer (Windows or Mac) – TIM is not supported on iPad.
  • The Belbo Satellite is installed and running on the computer. (Belbo Satellite guide)
  • The terminal is configured for ECR-integrated mode (card terminal integration) – your terminal provider sets this up.
  • The terminal has a fixed (static) IP address that is registered both in the router and with your terminal provider.
  • The computer and terminal are in the same WLAN or LAN network.
  • The terminal is reachable by ping from the computer – you can check this in Belbo under Settings → Card Terminal → Communication Test.
  • If the terminal does not have its own printer: The printer is also integrated via Belbo Satellite.

Setting up the connection in Belbo

  1. Enable the Card Payment function in Belbo under Settings → Add Function.
  2. Select "TIM/SIX" as the protocol.
  3. Enter the IP address of your terminal. You can obtain this from your terminal provider or from your router.
  4. Enter the port of your terminal. This will be provided by your terminal provider.
  5. Click Save.
  6. Go to the Assignment section and select the payment methods that should be transmitted to the terminal – typically EC and VISA.
  7. Have your terminal provider activate ECR mode on the terminal if not already done.

Testing the connection

Test the connection in two steps – first the communication test, then a real test transaction.

Step 1: Perform communication test

Open Settings → Card Terminal in Belbo and switch to the Communication Test tab. Belbo will now check whether the Belbo Satellite is reachable and whether the terminal responds to the registered IP and port.


Communication test green – terminal reachable

If the test is green, the connection is set up correctly. You can optionally click "Display text" – if "BELBO" appears on the terminal display, the communication is fully confirmed.

If the test is not green, fix the problem before proceeding. Common causes: Belbo Satellite not running, wrong IP or port, terminal and computer not in the same network. Further help: Troubleshooting EC Terminal

Step 2: Perform test transaction

Only after the communication test was successful, perform a checkout transaction and select one of the assigned payment methods. The amount will be automatically transmitted to the terminal.


Belbo shows amount as transmitted to terminal

If the amount appears on the terminal, the integration has been completed successfully.
