Step 1. The «Save for later use» checkbox

magento/magento2/blob/2.1.7/app/code/Magento/Braintree/view/frontend/web/template/payment/form.html#L107-L128


<!-- ko if: (isVaultEnabled())-->
<div class="field choice">
    <input type="checkbox"
           name="vault[is_enabled]"
           class="checkbox"
           data-bind="attr: {'id': getCode() + '_enable_vault'}, checked: vaultEnabler.isActivePaymentTokenEnabler"/>
    <label class="label" data-bind="attr: {'for': getCode() + '_enable_vault'}">
        <span><!-- ko i18n: 'Save for later use.'--><!-- /ko --></span>
    </label>
    <div class="field-tooltip toggle">
            <span class="field-tooltip-action action-vault"
                  tabindex="0"
                  data-toggle="dropdown"
                  data-bind="attr: {title: $t('What is this?')}, mageInit: {'dropdown':{'activeClass': '_active'}}">
                <span translate="'What is this?'"></span>
            </span>
        <div class="field-tooltip-content"
             data-target="dropdown"
             translate="'We store you payment information securely on Braintree servers via SSL.'"></div>
    </div>
</div>
<!-- /ko -->

Step 2.

The chosen «Save for later use» checkbox value is processed here:

github.com

magento/magento2/blob/2.1.7/app/code/Magento/Vault/view/frontend/web/js/view/payment/vault-enabler.js#L52-L52


data['additional_data']['is_active_payment_token_enabler'] = this.isActivePaymentTokenEnabler();

Step 3. Magento\Vault\Observer\VaultEnableAssigner::execute()

Step 4. Magento\Vault\Observer\AfterPaymentSaveObserver::execute()
