EMV - 無法生成CDOL1

AC命令

我已經成功地檢索CDOL1這是

9F02 06 - Authorised amount of the transaction (excluding adjustments) 
9F03 06 - Secondary amount associated with the transaction representing a cashback amount 
9F1A 02 - the country of the terminal 
95 05 - Status of the different functions as seen from the terminal 
5F2A 02 - the currency code of the transaction 
9A 03 - Local date that the transaction was authorised 
9C 01 - the type of financial transaction 
9F37 04 - Value to provide variability and uniqueness to the generation of a cryptogram 

如何創建基於此CDOL1的生成AC命令？

Answer 1

基於CDOL1你下一步將組裝CDOL1相關數據（即由CDOL1該標籤引用的數據對象值的表）：

[9F02 06 (Amount, authorized, numeric)]: 000000001000 (that's 1.00) 
[9F03 06 (Amount, other, numeric)]:  000000000000 (that's 0.00) 
[9F1A 02 (Terminal country code)]:   0040 (Austria) 
[95 05  (Terminal verification results)]: 0000000000 (or whatever TVR you need) 
[5F2A 02 (Transaction currency code)]:  0978 (Euro) 
[9A 03  (Transaction date)]:    150528 (2015-05-28) 
[9C 01  (Transaction type)]:    00 (whatever transaction type need) 
[9F37 04 (Unpredictable number)]:   12345678 

你會然後包數據到的數據字段的GENERATE AC命令APDU：

80 AE 5000 1D 000000001000 000000000000 0040 0000000000 0978 150528 00 12345678 00 

響應於此，你要麼得到包裹在標籤77（格式2），其由多個數據對象的響應消息數據字段。例如。如果不執行CDA，這可能是這樣的：

77 xx 
    [Cryptogram Information Data]  9F27 01 80 
    [Application Transaction Counter] 9F36 02 001B 
    [Application Cryptogram]   9F26 08 B31B2D16 69860BD5 
    [Issuer Application Data]   9F10 yy ... 
9000 [SW: success] 

或者你也可以得到包裹在標籤80（格式1）響應消息的數據字段。在這種情況下，該值是隱式數據對象的連續清單（標籤+長度字段不存在）：

80 xx 
    [9F27 01 (Cryptogram Information Data)]:  80 
    [9F36 02 (Application Transaction Counter)]: 001B 
    [9F26 08 (Application Cryptogram)]:   9F26 08 B31B2D16 69860BD5 
    [9F10 yy (Issuer Application Data)]:   ... 
9000 [SW: success]
