2% with Fidelity Rewards Visa Signature Card

The Fidelity Rewards card originally was an AMEX, but as of early 2016 it switched to Visa.  All existing accounts will be converted over to a Visa mid 2016.  It's easy to earn 2% on all your purchases with no limit.  A Fidelity account is necessary, but you can transfer the money out to a checking/savings account or keep your money with Fidelity.  Use the money in a brokerage, cash management, 529 or retirement account.  The extra step to get 2% vs 1% statement credit is well worth it if you want the cash.  Rates for the card are a little high, but don't get the card if you don't plan on paying it off monthly.
