Protocols used in Electronic Payment System:

  • Secure Sockets Layer (SSL) and Transport Layer Security (TLS)

SSL and its successor, TLS, are cryptographic protocols that provide secure communications over a computer network. They are widely used to secure web transactions between browsers and web servers by encrypting data in transit, thus preventing eavesdropping and tampering. Most online payment gateways use TLS to secure credit card transactions and other sensitive payment data.

  • Secure Electronic Transaction (SET)

Developed by Visa and MasterCard in collaboration with technology companies, SET is a protocol designed to secure credit card transactions over the internet. It ensures the confidentiality of payment and personal information, the authentication of all parties involved in a transaction, and the integrity of all transmitted data. Although not widely adopted, SET paved the way for the development of more robust payment security standards.

  • Payment Card Industry Data Security Standard (PCI DSS)

While not a communication protocol, PCI DSS is a critical security standard for organizations that handle branded credit cards from major card schemes. It prescribes measures for the protection of payment card information, including the use of secure network architectures, encryption, and access control measures. Compliance with PCI DSS is mandatory for merchants and service providers that process, store, or transmit credit card data.

  • 3-D Secure (3DS)

3-D Secure is an authentication protocol used by credit card companies to enhance online transaction security. It adds an additional layer of security by requiring cardholders to complete an additional verification step with the card issuer during online purchases. Versions include Verified by Visa, MasterCard SecureCode, and American Express SafeKey. The protocol helps to reduce fraudulent transactions and chargebacks.

  • Electronic Funds Transfer (EFT) Protocols

EFT protocols facilitate the electronic transfer of money between banks or bank accounts. Automated Clearing House (ACH) transactions, wire transfers, and direct deposits are examples of EFTs, governed by various standards and regulations depending on the country, such as the Federal Reserve’s Regulation E in the United States.

  • ISO 8583

ISO 8583 is an international standard for systems that exchange electronic transactions made by cardholders using payment cards.
