No, this module stores card data directly in the WHMCS database and uses direct server-to-server processing of card data with the Braintree gateway and does not rely on storing card data within the Braintree Vault. The module does not have the ability to use the Braintree Vault or vaulted payments and can only store and process cards directly within WHMCS. At this time, there are no plans to create such as module for Braintree.
