# Unico ID Pay

**Unico IDPay** is an innovative solution from Unico that combines, in a single verification, both the **identification of the shopper** and **the validation of the credit card's ownership**. This approach ensures safer transactions for remote purchases and helps **recover sales** that could otherwise be lost due to payment inconsistencies.

With **IDPay**, you **ensure** that:

* The user is live at the moment of the transaction;
* The identity matches the credit card holder;
* The credit card belongs to the person performing the transaction at your establishment;
  * The authorized and validated use of third-party cards is possible.

{% hint style="success" %}
What's more: you are **guaranteed liability** protection in case of validation errors (for more details, see the "Chargeback" section).
{% endhint %}

The operation is simple and efficient: a transaction is created from the **credit card number** and the **cardholder's CPF**, and IDPay handles the authentication of that transaction, either through facial biometrics or device metadata authentication.

In addition, IDPay is highly **flexible** and can be tailored to meet different scenarios and needs. Its platform offers a wide range of features that support various use cases, making it ideal for operations that require precision and security.

## 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://devcenter.unico.io/unico-idpay/en/about-idpay/unico-id-pay.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.
