How can I add the add-on provided by PayPal so that customers can purchase using bank cards without the need for a PayPal account?
By default, PayPal Express Checkout prompts customers to log in or create a PayPal account. However, in certain regions, you can activate guest payments to allow customers to pay with their credit cards without a PayPal account. To activate this feature, link your credit card to your PayPal business account and then adjust the settings in your PayPal account accordingly. Learn more about setting up guest payments on your checkout page at PayPal. To confirm whether you can activate guest payments in a certain country or region, contact the PayPal support team.
