# Using the M400 PINpad

This section describes the using procedures for the Verifone M400, in the following
\
sections:

* Zoom In and Zoom Out
* Smart Card Reader
* Magnetic Stripe Card Reader
* Contactless
* Line Items
* Signature Capture

### Zoom In and Zoom Out

Use the Zoom In and Zoom Out Feature to increase and decrease text size and screen resolution.

#### Increase Text Size and Screen Resolution

Touch the screen at the same time pinching your thumb and index finger close together and then spreading them apart.

#### Performing a Smart Card Transaction

{% stepper %}
{% step %}

#### Position the smart card

Position the smart card with the gold contacts facing upward.
{% endstep %}

{% step %}

#### Insert the card

Insert the card into the smart card reader slot in a smooth, continuous motion until it seats firmly.
{% endstep %}

{% step %}

#### Remove the card

Remove the card when the display indicates the transaction is completed.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
Leave the smart card in the card reader until the transaction is completed. Premature removal can void the transaction.
{% endhint %}

### Magnetic Stripe Card Reader

The Verifone M400 has a magnetic card reader that uses a triple track stripe reader. This gives the unit greater reliability over a wide range of swipe speeds and operating environments.

#### Performing a Credit/Debit Card Transaction

{% stepper %}
{% step %}

#### Position the card

Position a magnetic card with the stripe facing the keypad.
{% endstep %}

{% step %}

#### Swipe the card

Swipe it through the magnetic card reader.
{% endstep %}
{% endstepper %}

### Contactless

The Verifone M400 supports contactless transactions through an integrated contactless module. The terminal only becomes active for contactless smart card transactions when initialized by an application.

#### Performing a Contactless Transaction

{% stepper %}
{% step %}

#### Tap or hold the card

Gently tap the card onto or hold the card (within 1-2”) against the surface of the display where the contactless logo appears.
{% endstep %}

{% step %}

#### Confirm the transaction

An activated LED visual on the display accompanied by a short beeping sound indicates a successful transaction.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
Do not let metallic surfaces come in contact with the contactless module to ensure that it works properly.
{% endhint %}

### Line Items

Line items display on the Verifone M400 PINpad as the items are rang up on the POS.

### Signature Capture

The Signature Capture electronically captures a signature when required for a network sale. See the Signature Capture Feature Reference on the Premier Portal for more information.

* When a card is used and a signature is required, the customer is prompted for a signature on the Verifone M400 PINpad.
* The printed receipt does not include a signature line, but depending on the configuration settings, may include the signature image.
* Signature Capture saves receipt paper by allowing the cashier to decide whether or not to print a merchant and customer copy.
* Signature Capture only applies when a signature is required.

## 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/m400/using-the-m400-pinpad.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.
