Can this work with an unverified paypal? And how can you order a card of R1?
Also, can you then buy stuff with your Paypal after you put the balance on the Paypal?
R1 doesn't sell these anymore I believe. You don't need a verified PayPal to spend, there's just a limit which you can lift when you get your account verified.
Look up virtual credit cards.
Quick Edit: I think you can purchase virtual credit cards with an unverified PayPal.
