How to use multiple credit cards effectively (2026)
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 automating the decision with a router like Pikt.

Why most people pick the wrong card
Most people default to the same card at checkout — usually the one on top in their wallet. That habit quietly costs hundreds of dollars a year when another card in your stack earns 3×, 4×, or even 6× on the same purchase.
How Pikt routes smarter than guesswork
Pikt links the cards you already carry, weighs your offers and category earn rates, and tells you the best card to use — with a plain-English explanation and dollar estimate for every purchase. Online, the Pikt Checkout extension auto-fills that card at checkout; in-store, Pikt Nearby names it on your lock screen. Pikt removes the memory burden — you don't need to assign cards mentally when the app routes for you.
