{% endstep %}
{% endstepper %}

{% hint style="info" %}
If the secondary PIN pad is selected in between the transaction (after scanning the items), the primary PIN pad will be active after the transaction is completed.

If the secondary PIN pad is selected before the transaction, the secondary PIN pad will be active for the rest of the cashier session or until the cashier toggles the PIN pad or logs out of the session.
{% endhint %}

### Smart Card Reader Use

The smart card transaction procedure can vary depending on the application. Verify the proper procedure with your application provider before performing a smart card transaction.

#### Performing a Smart Card Transaction

{% stepper %}
{% step %}

#### Position the 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 Use

The P400 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 Use

The P400 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 %}

#### Present 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 %}

## 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/p400/using-the-p400-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.
