The ATR = 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 F0 04 00 00 00 00 9F
In which,
F0 04 = Topaz
Step 2) Read the memory address 08 (Block 1: Byte-0) without using Pseudo
APDU
<< 01 08
>> 18 [90 00]
In which, Response Data = 18
Or
Step 2) Read the memory address 08 (Block 1: Byte-0) using Pseudo APDU
<< FF 00 00 00 [05] D4 40 01 01 08
In which,
[05] is the length of the Pseudo APDU Data “D4 40 01 01 08”
D4 40 01 is the DataExchange Command.
01 08 is the data to be sent to the tag.
>> D5 41 00 18 [90 00]
In which, Response Data = 18
