Which of the following is a type of payment optimization within Stripe?

• A. Sigma
• B. Issuing
• C. Checkout and Radar
• D. Connect

Answer: (C)

Optimizing payments means improving how users complete purchases by boosting conversion, speeding processing, and reducing fraud and disputes. Stripe Checkout provides a ready-made, conversion-focused payment flow that handles card entry securely, supports wallets, and automatically manages compliance and frictionless flows such as 3D Secure when needed. Stripe Radar adds machine-learning–driven fraud detection to reduce fraudulent transactions and false declines, helping maintain strong authorization rates and lower chargebacks. Together, these tools directly enhance the payment experience and the reliability of processing, which is why they are the best example of payment optimization. Other options serve different purposes—analytics, card issuance, or platform payout capabilities—not directly optimizing the payment flow.
