You're right, Upromise® Mastercard® comes with this feature. Upromise Round Up lets you round up your purchases to the nearest dollar, based on the threshold you set (from $1 to $500). The total Round Up Amount is considered a purchase and also earns 1.25% cash back.

You may consider the Citi Rewards+® Card - the only credit card that automatically rounds up to the nearest 10 points on every purchase - with no cap (Citi is a Credit-Land.com advertising partner). Earn 2X ThankYou® Points at Supermarkets and Gas Stations for the first $6,000 per year and then 1X Points thereafter. Plus, earn 1X Points on All Other Purchases. So your $2 coffee earns 10 points. And a $22 dinner for two earns 30 points. What is more, earn 20,000 bonus points after you spend $1,500 in purchases with your card within 3 months of account opening; redeemable for $250 in gift cards at thankyou.com.
