No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
One of the cards in my portfolio is the PenFed Pathfinder. While I have other cards with constant cash back earn rates, I wouldn't mind consolidating my 2% card to be one with PenFed instead (thinking of the PenFed Power Cash card to be more precise). All that said, does PenFed allow you to pool points earned between your various cards that you have with them or do points earned between cards only exist individually?
I'm not sure on the answer to your question, however the PCR is cashback, not points based, so just as an FYI, make sure you use all your points up prior to PCing (unless you plan on opening a new account instead).
There isn't a single consolidated splash page that manages redemptions across all cards. Rewards info is presented for each card individually from the main page and the format for each is identical other than the rewards balance for the PCR is in dollars and not points, but the PCR's Redeem Rewards link brings you to a different page dedicated to PCR cash redemptions, and they support redemptions to both internal and external accounts.
