Kristi from Braintree here. You can securely store the card info to the Braintree vault so the user only has to enter the credit card info in your app one time. You won't be able to save credit cards to the device to use across apps.

Will we be able to do the same for Paypal credentials? So if someone wants to do paypal, store that and charge later?

Yep, you're able to save PayPal credentials to the vault. From there, you can treat it exactly like you would a stored credit card.
