If your beau has a 25 year history with one card and little revolving debt he should have NO problem. Have you considered the Sapphire card from Chase? Give them a call, they may transfer him to a different, more rewarding program, but if he just opens a new account (and keep the old one) he is more likely to get the new account sign up bonuses that you wouldn't get from converting. You don't have to be concerned with inquiries unless you are applying for a half dozen cards.
Credit cards basically fall into 3 categories with little overlap:
1) Rewards- These cards are great for those that pay in full monthly. Great rewards, high interest (airline and hotel cards, AMEX, Chase Sapphire, Citi Diamond)
2) Low APR- Little or no rewards, but great for carrying a balance if you have good credit (Simmons, PenFed Promise, IberiaBank)
3) Bad credit/No credit- High APR, low limit, no rewards (Orchard, First Premier)
Regarding the Capital One Cash Credit Card, it looks ok, but there are better cash back cards out there. Discover has several cards with 1% back across the board plus bonus categories that change quarterly (ex, maybe you get 3% on fuel from Jan. to March). American Express Blue Cash
is a great program for earning cash rewards.
Rewards are generally points OR cash back, so you have to pick one or the other to maximize your rewards.
Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same.
