Karta Card Design Case Study: AI Metal Credit Card

Karta global credit card adventure

People often have several cards, and at high spending levels, banks compete to attract them and build their loyalty.

The problem: outdated services and cards that no one shows off. Karta was created for this purpose: a modern card that understands its holder and becomes their favorite for traveling, creating memorable moments.

 

  • Challenge

Credit cards have not adapted to modernity with AI.

Traditional credit card providers offer a 20th-century service. It’s time to have a credit card that truly understands the user.

  • Metallic card: As part of the premium perception. The card must be metallic, competing with Amex Centurion.
  • Users perceive: They typically have three credit cards. We need to time Karta's use perfectly and ensure the experience is remarkable.

Early versions of the credit card

In a Matter of Days, we learned

We leverage AB testing with short sprints to iterate quickly and improve conversion.

  • 4/5 users did not like the card: It didn't inspire confidence. They felt an old but modernized vibe.
  • 5/5 users compared with Amex Centurion: Comparing the designs, Amex was still beating us.
  • 3/5 users want to show off their card: Not only do they use it to pay, but when they take out their card to pay, it speaks to their unique personality.

Quick, Dynamic and Unique Conversations

Quick conversations via WhatsApp helped us iterate quickly.
