# Card Terminal

> Connect this device to a card payment terminal

Go to **Setting → Card Terminal** to choose and test the card payment terminal this device connects to.

## Choosing a terminal provider

1. Tap **Setting → Card Terminal**.
2. Select your **Terminal Provider** from the dropdown (e.g. PayHere Direct (ECR)).
3. Tap **Save Settings**.

<Info>
  The terminal's **IP, port, and API key** are configured separately in the **Admin Portal**, under **Payment Types** — not on this device. This screen only selects which provider this device uses and lets you test the connection.
</Info>

## Testing the connection

1. Under **Test Connection**, tap **Test Connection**.
2. The app pings the terminal configured in the Admin Portal to confirm it's reachable.
3. The result (success or failure) shows below the button.

<Tip>
  If the test fails, confirm the terminal is powered on and connected to the same network, and double-check the IP/port/API key configured in the Admin Portal under Payment Types.
</Tip>

## How it works

DuitPOS connects directly to the card terminal over your local network — no separate bridge app is needed for supported providers.

**Supported actions** (varies by provider): Card (Seamless) payments, DuitNow QR, Void, Settlement, and Reprint.

<Note>
  Once connected, card payments taken during [Settling a Bill](/pos-app/payments/settling-a-bill) route through this terminal automatically — no extra steps needed at checkout.
