CardShark

Pick the right credit card every time at checkout for maximum rewards.

Love cash back or frequent flyer miles? With bonus categories changing every quarter, it's impossible to keep the varying reward levels straight in your head. CardShark tells you which card in your wallet will give you the most rewards at the merchant you're visiting.
