金融交易卡发起的消息 交换消息规范

[中文适用范围]： 本文档规定了一个通用接口，通过该接口，收单机构和发卡机构可以交换金融交易卡发起的消息。它规定了消息结构和格式，包括规范化的数据类型。消息、字段、值定义和支持信息由 ISO 8583 维护机构 (MA) 提供。ISO 8583 MA 的联系方式和网页信息可在以下位置找到：https://​ www​ .iso​ .org/​ Maintenance​ _agencies​ .html。传输消息或进行结算的方法不在本文档的讨论范围内。注意：随着金融机构向客户提供服务的技术不断涌现，现在存在一系列用于识别账户关系的令牌（例如金融交易卡）。为了保持清晰度，本文档将继续使用适用于令牌和卡的卡术语，除非该元素特定于令牌或卡，在这种情况下它将被标识为令牌或卡。但是，金融机构发行的实际令牌数字可能与关联的卡数字不同。 [外文原描述]： This document specifies a common interface by which financial-transaction-card-originated messages can be interchanged between acquirers and card issuers. It specifies message structure and format, including normalized data types. Message, field, value definitions and supporting information are provided by the ISO 8583 maintenance agency (MA). Contact and web page information for the ISO 8583 MA can be found at: https://www.iso.org/maintenance_agencies.html. The method by which messages are transported or settlement takes place is not within the scope of this document. NOTE With the proliferation of technology available to financial institutions to offer services to customers, a range of tokens now exist for identifying account relationships (e.g. financial transaction cards). In order to maintain clarity, this document will continue to use card terminology that applies to tokens and cards, unless the element is specific to tokens or cards, in which case it will be identified as such. However, the actual token numeric issued by a financial institution can be different from the associated card numeric.
