That's actually not how most of e-commerce payment works nowadays. If you use Shopify, merchant doesn't see your credit card. Same for SquareSpace. Same for Salesforce Commerce Cloud / Demandware, where everything is more often integrated with Stripe/Paypal directly and merchant never even see it. Very rare the merchants that will actually "see" your credit card.

Merchant doesn't pass your information to the PSP, you are actually talking to the PSP directly.
