[英]Difference between EMV tags and ISO 8583 Data Elements

原文 2022-06-11 03:48:00 9 1 emv/ iso8583

Just wanted to know what the difference between EMV tags and data elements is只是想知道EMV标签和数据元素之间的区别是什么

For example EMV books specify PAN to be contained in 5A tag however ISO 8583 mentions PAN to be present in DE2 element例如，EMV 书籍指定 PAN 包含在 5A 标签中，但是 ISO 8583 提到 PAN 存在于 DE2 元素中

Does that mean that these Data Elements are nothing but a collection of these emv specified tags ?这是否意味着这些数据元素只不过是这些 emv 指定标签的集合？

For example DE2 contains the 5A tag?比如DE2包含5A标签？

Both are specifications.两者都是规格。 ISO8583 deals with the request response messages between different institutions, as per ISO.根据 ISO，ISO8583 处理不同机构之间的请求响应消息。 Each payment schema( eg. Visa, MasterCard, .. ) have their own implementation of ISO8583 which is to be followed when sending/receiving messages to/from them.每个支付模式（例如 Visa、MasterCard、..）都有自己的 ISO8583 实现，在向/从它们发送/接收消息时要遵循。

EMV is a consortium of payment schemes, and it has specification as to how chip and terminal should communicate with each other, 3D secure, QR code specifications etc. So mostly dealing the acquirer side. EMV 是一个支付方案联盟，它有关于芯片和终端应该如何相互通信、3D 安全、QR 码规范等方面的规范。所以主要处理收单方。
