On the Kudos Browser Extension
Once Kudos is set up and your cards are added, you'll see a yellow badge at the bottom right of your browser while you shop. Click the badge to view your personalized card recommendations ranked by earning potential. Beyond showing your top-earning card, Kudos reveals hidden perks like purchase protection and extended warranty coverage, too.
If the yellow badge doesn't appear, find the Kudos icon in your browser's extension toolbar and click it to open your wallet to see your cards and the rewards they earn at the store you're visiting.
As you proceed to checkout, we'll crunch the numbers to show you the rewards you'll rack up with the ideal card. Plus, you'll earn Kudos Boost cashback at over 15,000 stores.
