# Use Case
source: https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/index.md

The Pre-Digitization API can be used in the following use cases:
[Token Requestor Initiated Tokenization](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/tokenization/index.md) -
Token Requestor checks whether a card is available (within an allowed account range) for digitization. The digitization outcome is one of the following:

* [Approve](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/tokenization/index.md#approve)
* [Approve, but require authentication](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/tokenization/index.md#approve-but-require-authentication)
* [Decline](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/tokenization/index.md#decline)
[Authentication and Activation for Device Wallets](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md) -
Token Requestor checks whether a card is available (within an allowed account range) for digitization. The cardholder is then authenticated pre-tokenization for the device wallet using one of the following authentication methods:

* [Activation Code for token activation](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md#activation-code-based-authentication)
* [Issuer App and TAV for token activation](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md#issuer-app-and-tav-for-token-activation)
* [Issuer App and Customer Service API for token activation](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md#issuer-app-and-customer-service-api-for-token-activation)
* [Customer Service for token activation](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md#customer-service-for-token-activation)
* [Authentication using EMV 3-D Secure](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/pre-tokenization-authentication/index.md#authentication-using-emv-3-d-secure)
[Issuer Initiated Tokenization](https://developer.mastercard.com/mdes-pre-digitization/documentation/use_case/issuer-tokenization/index.md) -
Issuer-initiated digitization provides a digitization experience driven by the issuer, from the issuer's app or website. The issuer pushes an account number to the Token Requestor's environment to create a token. Issuer-initiated digitization is also referred to as Push Provisioning.
Note: The Pre-Digitization APIs are available for use by issuers and issuer's processors globally.
