Context:

How are the payment data assigned to the Vault payment method instance on an order placement?
How does the Braintree module saves the current bank card for a later use?

The single usage

It is a handler of the payment_method_assign_data event:

magento/magento2/blob/2.1.7/app/code/Magento/Vault/etc/events.xml#L12-L14


<event name="payment_method_assign_data">
    <observer name="vault_enable_assigner" instance="Magento\Vault\Observer\VaultEnableAssigner" />
</event>

This event is triggered by the Magento\Payment\Model\Method\Adapter::assignData() method.
