Paypal does have a future payments token capability [1]. The user must explicitly authorize the merchant the ability to use the token in order to use it for future transactions. We save the email for reference, but we never save the password.
Can Paypal (not Braintree) also authorize future Credit Card purchases from the same user without having to enter the CC number again? As in, could PayPal pass me a customer ID when someone purchases with CC via PayPal?
