Show “Enter PIN:” means enter the old/current PIN and
Show “Enter New PIN”
Show “Confirm New PIN”
• Point 1: Lc (12h) equal to SpeOffsetNew (0Ah) + SpePINLen (6) + SpePinPos (2)
• Point 2: SpeOffsetNew (0Ah) >= SpeOffsetOld (1) + SpePINLen (6) + SpePinPos (2)
• Point 3: SpePINPos (2 Bytes) >= SpePinLenPos (1 Byte) + SpePINSize (4 bits)
• Point 4: SpePINLen (6) = [SpePinMax (0Ah) * 4bits(BCD)] = 5 bytes
: 6 bytes >=5 bytes
• Point 5: SpePinMax (0Ah) > SpePinMin (01h)
• Point 6: SpePinMax (0Ah) <=10h
• Point 7: SpePinMin (01h) >= 01h
