Published by Pikt. Published . Updated .
Use multiple cards effectively by assigning each to its strongest category — dining card for restaurants, grocery card for supermarkets, 2% card for everything else — and letting Pikt name which one to use.

Why the answer varies
The likely winner depends on the cards a person carries, the merchant category, active bonus categories and offers, reward values, earnings caps, known fees, and issuer terms. Card acceptance can also remove an otherwise higher-earning option. A public guide is a general comparison until a user provides their own wallet.
Pikt personalizes each estimate to the cards you already carry, the purchase details, and any reward values you set. It compares supported earn rates, eligible offers, caps, and card constraints, then explains the result. Use Card Check for a recommendation based on the cards you carry.
Why the usual card can earn less
Most people use the same card at checkout, usually the one on top in their wallet. Another card you already carry can earn more on the same purchase. Extra shown is estimated. Your issuer decides final rewards.
How Pikt compares your cards
Enter the store and amount. Pikt estimates which card in your wallet is likely to earn the most, with the dollar difference and a short reason. Issuers decide. Online, Pikt Checkout names that pick before you click pay. On recurring bills, Subscriptions shows which card is likely to earn the most and how to put it on file. Coming next: Pikt Signal will put your best card on your lock screen when you're ready to pay in stores. Pikt removes the memory burden — you do not need to assign cards mentally when it names one.
