I think when we use credit or debit cards online there are many security concerns like landing your sensitive information in wrong hands. But if we link our credit/debit card details to our Paypal account we can shop online using our PayPal account and we don't have to share our card details time and again. So this is somewhat more secure I guess. But if I don't want to link my card details with PayPal is there any other indirect payment method than PayPal? I am also not able to directly use the fund in PayPal due to PayPal policies in our country.
