# Using the M425A PIN Pad

## Using the M425A PIN Pad

Customers follow the same payment flow as earlier terminals. They tap, insert, or swipe their card, then enter a PIN if prompted.

### Daily operation

| Situation                     | What to do                                                                     |
| ----------------------------- | ------------------------------------------------------------------------------ |
| Customer pays at the pump     | No cashier action is needed. The customer follows on-screen prompts.           |
| Customer pays indoors         | Process the sale normally. The M425A prompts the customer to present payment.  |
| Customer scans a loyalty code | Ask the customer to show the barcode or QR code near the terminal scanner.     |
| Terminal is updating          | Do not power off the terminal. It returns to the payment screen automatically. |
| A card is declined            | Ask the customer to use another payment method.                                |

### Smart-card transactions

1. Position the card with its gold contacts facing upward.
2. Insert it smoothly into the smart-card reader.
3. Leave it inserted until the display confirms completion.

{% hint style="warning" %}
Removing a smart card before completion can invalidate the transaction.
{% endhint %}

### Magnetic-stripe transactions

Wait until the terminal is ready for a magnetic-stripe transaction. Position the card with its stripe facing the keypad and swipe it through the reader.

### Contactless transactions

Hold the card, phone, or watch within 4 cm of the contactless symbol. The terminal confirms a successful transaction with LEDs and a short beep.

{% hint style="warning" %}
Keep metallic objects away from the contactless reader.
{% endhint %}

### Zoom the display

To increase text size, place two fingers together on the screen and spread them apart. Pinch inward to reduce text size.

### Line-item display

The M425A can show items as the POS rings them up. Enable this feature in Commander Configuration Client:

**Payment Controller** → **EPS Configuration** → **EPS Global Configuration** → **POP**.

### Signature capture

When a payment network requires a signature, the terminal prompts the customer to sign on-screen. The printed receipt does not include a signature line. Depending on configuration, it can include the signature image.

### Customer-facing features

The terminal can support QR and barcode scanning, loyalty recognition, on-screen tipping, promotions, and configured alternative payment methods.

Contact your Verifone deployment team to enable or customize these features.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://commanderhelp.verifone.com/customer-documentation/petro-and-c-store/pin-pads/implementation-guides/m425a/using-the-m425a-pin-pad.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
