Secure online transactions are created using encryption and secure payment technologies such as SSL/TLS protocols. These technologies protect sensitive information, like credit card details and personal data, during transmission over the internet. By encrypting data, they prevent unauthorized access, ensuring privacy for both businesses and customers. Additionally, established payment gateways securely process transactions, enhancing trust in online shopping experiences. This combination of security measures is critical for fostering confidence in e-commerce and encouraging consumer participation in digital marketplaces.
