E-commerce employs various technologies for online payment processing, including secure sockets layer (SSL) encryption, payment gateways, and tokenization. Payment gateways facilitate transactions by connecting customers' payment methods to the merchant's bank. SSL provides data encryption to protect sensitive information from fraud. Furthermore, third-party processors like PayPal and Stripe manage payments, enhancing security and efficiency. These technologies ensure a seamless and secure payment experience, crucial for customer trust and satisfaction in online shopping.
