Identification card systems - Telecommunications integrated circuit(s) cards and terminals - Part 5: Payment methods

This specification outlines the technical requirements for payment methods within the context of telecommunication integrated circuit cards and their terminals used in identity document systems. It establishes the fundamental architecture and data exchange protocols necessary to ensure secure and reliable financial transactions processed through smart card technology. The document details the specific communication procedures and logical data structures that enable the authorization and execution of payment operations between the card and the reading device. It covers the essential elements required to maintain data integrity and confidentiality during the transaction lifecycle, including the mechanisms for key management and authentication processes. Furthermore, it defines the interface specifications that allow interoperability between various terminal implementations and card issuers across different operational environments. This framework supports the efficient handling of monetary value transfers within identity-related applications, ensuring consistency in performance and security standards. The guidelines provided facilitate the development of compatible systems by setting clear parameters for data formatting and error handling, thereby promoting a unified approach to electronic payment solutions in this specific sector.
