# Mastercard CDCVM
### Overview
This page describes CDCVM behavior for a Mastercard digital card.
### Supported CDCVM variants
Mastercard supports two CDCVM variants in the `MCBPv2` digital card profile:
* `FLEXIBLE_CDCVM` supports LVT without authentication and transit payments without authentication.
* `CDCVM_ALWAYS` requires **end user** authentication for every transaction.
### Low-value transaction (LVT)
For Mastercard, the terminal determines whether a transaction is an LVT.
It uses data in the `Generate AC` APDU command, including the CVM result and terminal capabilities.
To support LVT without authentication:
* The Mastercard digital card profile must be `FLEXIBLE_CDCVM`.
* 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).
### Transit payment without authentication
For Mastercard, NFC Wallet SDK treats a transaction as a transit transaction when both conditions are true:
* The transaction amount is `0`.
* The transaction `MCC` identifies a transit merchant.
To support transit payments at a transit gate without authentication:
* The Mastercard digital card profile must be `FLEXIBLE_CDCVM`.
* You must enable transit payment without authentiction 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).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.payments.thalescloud.io/nfc-wallet-sdk-android/implement-nfc-wallet/make-payment/implement-contactless-payments/7.-configure-cdcvm-experiences/mastercard-cdcvm.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
