# PURE CDCVM

### Descripción general

Esta página describe el comportamiento CDCVM para una tarjeta digital PURE (red de pago EMV de marca blanca de Thales).

{% hint style="info" %}
Ver [Prioridad CVM de PURE](/nfc-wallet-sdk-android/es/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/pure-cdcvm/pure-cvm-priority.md) para detalles sobre la selección de CVM entre la aplicación de billetera digital y el terminal POS.
{% endhint %}

### Transacción de bajo valor (LVT)

Usando PURE, una transacción es determinada como LVT por el terminal junto con `CIAC-CVM` valor del perfil de la tarjeta digital. 

Los perfiles PURE pueden clasificarse en `TTPI` (Información de procesamiento de transacciones del terminal) perfil y no`TTPI` perfil:

*  `TTPI` perfil
  * admite el procesamiento de CVM durante `Obtener opciones de procesamiento` (`GPO`) comando APDU y puede solicitar autenticación después de `GPO` comando.
  * `TTPI` El bit 7 del byte 2 indica si la transacción requiere autenticación (HVT) por parte del terminal.
* no `TTPI` perfil
  * procesa CVM durante `Generar criptograma de aplicación` (`GenAC`) comando APDU.
  * `Resultados CVM` en `GenAC` comando indica si la transacción requiere autenticación (HVT) por parte del terminal..

Para admitir LVT sin autenticación:

* Debe habilitar la experiencia de pago LVT como se describe en [Definir gestión de riesgos](/nfc-wallet-sdk-android/es/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/define-risk-management.md).

{% hint style="info" %}
El perfil de tarjeta digital PURE proporciona algunos parámetros de riesgo para LVT sin autenticación como se describe en [Gestión de riesgos Pure](/nfc-wallet-sdk-android/es/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/define-risk-management.md#pure-risk-management)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.payments.thalescloud.io/nfc-wallet-sdk-android/es/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/pure-cdcvm.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.
