Have a ton of different credit cards? Feel like you’re missing out on the best rewards? We just stumbled upon Kard, a fully automated tool designed to notify you of the best deals across all of your credit cards in real-time.

More details about Kard:

Kard is a free tool that puts all your credit card rewards in one place, with no personal information required. That’s right: you don’t have to give up your bank log-in information, your credit card number, or any other usernames and passwords.

All Kard needs to know are what types of credit cards you have (Chase, AMEX, etc), and Kard‘s Chrome Extension will notify you whenever you have a deal available as you shop online, allowing you to earn more miles, points, and cash back on everything from daily purchases, to that occasional splurge.

What are you waiting for?! It’s free, so what do you have to lose?.
