Ever wondered which card has the highest cash back when making a purchase? Wonder no more! The Busy bee app will tell you at the tap of a button. Simply tap on the merchant where you are making a purchase, and the app will show you the best cards to use. If the merchant is not shown on the map near you, you can also search for it in the search bar. You can also search for the cash back category name (e.g. dining), and it will display the cards with the highest cash back.
