abPINApdu = 00 24 00 01 09 57 30 30 30 30 30 30 30 30h
After Lc (09h), the first 1 byte 57h is control character
bConfirmPIN = 01h (If bConfirmPIN=01h, bNumberMessage must equal to 02h)
Enter the New Pin and confirm the New Pin
bmFormatString=89h
SpePinPos=1 byte because bmFormatString bit 7 = 1

Show “Enter New PIN:” and
Show “Enter Confirm PIN”
PIN Input = 1 2 3 4 5 6 7 8 0
• Point 1: Lc (9) equal to SpeOffsetNew (0) + SpePINLen (8) + SpePinPos (1)
• Point 2: SpePINPos (1 Byte) >= SpePinLenPos (4 bits) + SpePINSize (4 bits)
• Point 3: SpePINLen (9) – SpePinPos (1 Byte) >=[SpePinMax (0Ah) * 4 bits(BCD)] = 5 bytes
: 8 bytes >=5 bytes
• Point 4: SpePinMax (0Ah) > SpePinMin (01h)
• Point 5: SpePinMax (0Ah) < =10h
• Point 6: SpePinMin (01h) >= 01h
