# PURE CDCVM

### Overview

This page describes CDCVM behavior for a PURE (Thales white-label EMV payment network )digital card.

{% hint style="info" %}
See [PURE CVM priority](/nfc-wallet-sdk-android/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/pure-cdcvm/pure-cvm-priority.md) for details about CVM selection between the digital wallet application and the POS terminal.
{% endhint %}

### Low-value transaction (LVT)

Using PURE, a transaction is determined LVT by the terminal together with `CIAC-CVM` value from digital card profile. 

PURE profiles can be classified into `TTPI` (Terminal Transaction Processing Information) profile and non-`TTPI` profile:

*  `TTPI` profile
  * supports CVM processing during `Get Processing Options` (`GPO`) APDU command and may ask for authentication after `GPO` command.
  * `TTPI` Byte 2 Bit 7 indicates if the transaction requries authentication (HVT) by terminal.
* non `TTPI` profile
  * processes CVM during `Generate Application Cryptogram` (`GenAC`) APDU command.
  * `CVM Results` in `GenAC` command indicates if the transaction requries authentication (HVT) by terminal..

To support LVT without authentication:

* You must enable the LVT payment experience as described in [Define risk management](/nfc-wallet-sdk-android/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/define-risk-management.md).

{% hint style="info" %}
PURE Digital card profile is providing with some risk parameters for LVT without authentication as described in [Pure risk management](/nfc-wallet-sdk-android/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/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.
