EMV标签和ISO 8583数据元素之间的差异
只是想知道EMV标签和数据元素之间的区别是
例如EMV书籍指定要包含在5A标签中的PAN，但是ISO 8583提到DE2元素中存在的PAN
确实意味着这些数据元素无非这些EMV指定的标签？
例如，de2包含5A标签？
Just wanted to know what the difference between EMV tags and data elements is
For example EMV books specify PAN to be contained in 5A tag however ISO 8583 mentions PAN to be present in DE2 element
Does that mean that these Data Elements are nothing but a collection of these emv specified tags ?
For example DE2 contains the 5A tag?

两者都是规格。 ISO8583根据ISO处理不同机构之间的请求响应消息。每个付款模式（例如Visa，MasterCard，..）都有其自己的ISO8583实施，该ISO8583在向其发送/接收消息时应遵循。
EMV是一个付款计划的财团，它具有有关芯片和终端如何相互通信的规范，3D安全，QR码规格等。
Both are specifications. ISO8583 deals with the request response messages between different institutions, as per ISO. Each payment schema( eg. Visa, MasterCard, .. ) have their own implementation of ISO8583 which is to be followed when sending/receiving messages to/from them.
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.
