banking protocol

**banking protocol**

A banking protocol refers to the standardized set of rules and procedures that govern the secure and efficient exchange of financial information between banks and their clients or between different banking institutions. These protocols ensure the integrity, confidentiality, and authenticity of transactions conducted over digital channels, supporting activities such as fund transfers, payments, account management, and compliance with regulatory requirements. Common examples include SWIFT, ISO 20022, and PCI DSS standards. Understanding banking protocols is essential for developers, financial professionals, and businesses engaged in digital banking and financial technology.
