Result APDU in byte
format
66 24 68 ac f0 10 30 30 30
The whole APDU in byte format will be:
00 24 00 01 0A 20 66 24 68 ac f0 10 30 30 30h
If arrangement is Right:
bmFormatString change to=3Dh
00 24 00 01 0A 20 67 30 30 30 31 23 45 67 80h
If SpeOffsetNew = 00h and abPINApdu = 00 24 00 01 09 57 30 30 30 30 30 30 30 30h
bmFormatString change to=39h
The result formatting APDU = 00 24 00 01 09 66 24 68 AC F0 10 30 30 30h
12.10. Modification Example 2
It is the same as example 1, only bConfirmPIN is changed to 01h.
abPINApdu = 00 24 00 01 0A 20 57 30 30 30 30 30 30 30 30h
bConfirmPIN =
01h (If bConfirmPIN=01h, bNumberMessage must equal to 02h )
Enter the New PIN and confirm the New PIN.
bmFormatString=39h
SpePinPos=7 bits because bmFormatString bit 7 = 0
SpeLeftRight=Left
SpePINTyp=BCD
bmPINBlockString=49h
SpePINSize=4 bits
SpePINLen=9 bytes
bmPINLengthFormat=02h
SpePINLenPos=2 bits
