What are the differences between using a debit card and PayPal for online transactions?

The main difference between using a debit card and PayPal for online transactions is that a debit card directly accesses your bank account, while PayPal acts as a middleman between your bank account and the merchant. Debit cards are issued by banks and are linked to your account, while PayPal is a digital payment platform that stores your payment information securely. Debit cards offer direct access to your funds, while PayPal provides an extra layer of security by not sharing your financial information with the merchant.
