Which is an example of creating payments using the customer object to help with fraud prevention?

• A. Save cards to customer objects and use them to create subsequent payments
• B. Provide your customer's email address when creating a customer object
• C. Provide your customer's name when you tokenize their card information
• D. Do not store any customer data

Answer: (A)

Saving a card on the customer object and using that stored payment method for subsequent charges is the best way to support fraud prevention. By attaching a payment method to a specific customer, Stripe can apply risk checks, authentication, and ongoing monitoring across that customer’s payments. This creates a consistent identity, reduces the need to handle raw card data on your side, and enables Radar and 3D Secure flows to trigger when risky activity is detected, helping prevent fraudulent charges. Merely providing an email or a name during tokenization doesn’t give you the same ability to track and assess risk over time, and not storing customer data prevents you from leveraging these protective signals.
