The technology crucial for enabling secure online transactions is typically based on encryption protocols, such as Transport Layer Security (TLS). These protocols ensure that data transmitted between users, websites, and payment gateways is protected from interception and tampering. Encryption scrambles sensitive information, making it unreadable to unauthorized parties, thus ensuring confidentiality and integrity of the data exchanged during online transactions. Businesses that implement secure encryption measures build trust with customers and comply with regulatory standards, ultimately fostering a safe online shopping experience.
