如何阅读基于EMV的智能VISA卡详细信息 [英] How to Read EMV based smart VISA card details

问题描述

我正在尝试从VISA卡中读取信用卡数据，但无法成功.在互联网资源中，我发现对于MASTER卡，我们可以使用1PAY.SYS.DDF01选择PSE目录文件，然后读取记录.但是对于VISA来说，这不是强制性的，当我使用SELECT命令使用以下文件获取PSE目录时，响应为'6A82'.这意味着文件系统不支持该文件.我在EMV 4.2规格书1(EMV规范)中寻找错误，它说我们必须使用"AID列表".它说:终端使用列表中的下一个AID发出另一个SELECT命令". 我无法理解这一点，并继续进行下去.

I am trying to read the credit card data from the VISA card but could not able to make a success.As in the internet resources I have found that for the MASTER card we can select the PSE directory using 1PAY.SYS.DDF01 file and then read the records. But for VISA its not mandatory and when I use the following file using SELECT command for getting the PSE directory I get the response as '6A82'.Which means its is not supported by the file system. I looked for the Error in the EMV 4.2 Book 1(EMV specification) and it says that we have to use a "List of AIDs". It says "The terminal issues another SELECT command using the next AID in its list". I am unable to understand this and proceed further.

有关如何获取VISA卡的PSE或AID以获得信用卡详细信息的帮助吗?

Any help on how to get the PSE for the VISA card or the AID to get the credit card details?

谢谢， 谢克尔

推荐答案

首先，PPSE小程序对VISA或万事达卡都不是特定的.它由EMV定义，并且如您正确地注意到的那样用于在卡上列出可用的支付应用程序的AID.但是，如果不存在，则终端会尝试所有受支持的AID来构建候选列表.

First of all PPSE applet is nothing specific for VISA nor for MasterCard. It is defined by EMV, and it is used as you correctly noticed for listing the AIDs of the available payment applications on the card. But if it is not there the terminals try all the supported AIDs to build the candidate list.

如果要选择VISA小程序，但不知道完整的AID，则可以使用部分选择.由于所有的VISA AID都以VISA的RID开头:A0 00 00 0003.您可以尝试发送以下命令:

If you want to select the VISA applet, but you do not know the complete AID you can use partial selection. Since all the VISA AIDs begin with the VISA's RID: A0 00 00 00 03. You can try to send this command:

这将返回第一个实例:

00 A4 04 00 05 A0 00 00 00 03 00

00 A4 04 00 05 A0 00 00 00 03 00

这将为您提供更多帮助:

and this will give you more if you have on your card:

00 A4 04 02 05 A0 00 00 00 03 00

00 A4 04 02 05 A0 00 00 00 03 00
