java - 无法使用 EMV 非接触式 (Interac Flash) 从借记卡读取 PAN

Question

尝试在支持 NFC Interac Flash 的卡上使用标准 EMV 协议(protocol)读取借记卡号。

这是我的交易顺序:

响应3:6985(不允许命令；不满足使用条件。)

我无法通过 6985 错误；经过 2 天的规范阅读和反复试验。

从借记卡 (Interac) 读取卡号的任何提示/想法/成功示例？被测卡为具有Interac Flash非接触式功能的TD借记卡。

非常感谢!

--- 注意:我能够在没有 GET PROCESSING OPTION 的情况下从 Visa 和 MasterCard 读取卡号。但是由于我一直在没有 GPO 的情况下获得 6985，所以我尝试这样做，但失败了。我真的不需要做 GPO，只需要获取卡号和到期日期。 ---

Answer 1

“Interac 直接支付的双界面读卡器/终端规范” 1.4 版表明，当内部应用程序交易计数器 (ATC) 达到其最大值时，卡应响应 SW1 SW2 = 6985:

3.2.6 GET PROCESSING OPTIONS command

... If ATC reaches its maximum value (‘FFFF’), the card response to GET PROCESSING OPTION is SW1SW2 = ’69 85’.

但是，由于对其请求的 PDOL 的响应无效，卡可能会拒绝 GET PROCESSING OPTIONS (GPO) 命令。以下是 GPO 命令中发送的值与有效 Interac Flash 事务中发送的值的比较:

TAG  LEN MEANING                                YOUR SAMPLE    VALID SAMPLE

9F02 06  amount, authorised                     000000000000   000000001000

5F2A 02  Transaction currency code              0124           0124
9F37 04  Unpredictable number                   00000123       823DDE7A 
9F58 01  Merchant Type Indicator                00             01

你会注意到:

1. 终端交易信息似乎无效。应根据您的阅读器能力进行设置。
2. 卡可能不支持该金额:您正在尝试进行 0 美元的购买。
3. 商家类型标识无效(有效值范围为 01 到 05)

一旦您更正了这些值，卡很可能会接受 GPO 命令，您将能够使用 READ RECORD 命令读取 PAN。

希望这对您有所帮助。
