Wc Checkout Redirect: How to avoid PayPal or Stripe ban/limit/suspension for high-risk items?

Description:
How payment page redirection works:
1. the customer adds the product to the cart
2. If he clicks on go to Checkout on site A he will be redirected to confirm the payment on the Checkout page of site B
3. A PopUp will appear to confirm the payment on the same origin site A without leaving the original product page.
4. Once the payment is confirmed on the PopUp, the customer will be redirected to the home page of the original site A so that the customer will never feel that he has paid on another external URL!

A. A minimalist Checkout page
B. Payment is made on the product page without leaving the original site.
C. Avoid the limitation and suspension of accounts such as PayPal and Stripe if you market so-called high-risk items
