8.5. SECURE PIN MODIFY

The SECURE PIN MODIFY command can be called in two ways:
1. For the explicit Secure Pin Modify, host should send two commands separately, one is
SECURE PIN ENTRY and another one is SECURE PIN MODIFY, for example:
Secure PIN Entry (Host->Reader): 69 1C 00 00 00 00 F3 00 00 00 00 00 89 47 04 0C 04 07
01 09 04 00 00 00 00 00 20 00 02 08 2C FF FF FF FF FF FF FFh
LCD display: " Enter auth. Pin:"
User enter 12 digits long PUK: e.g. 3 3 3 3 3 3 1 1 1 1 1 1
LCD display: "Card inserted"
Secure PIN Entry (Reader->Host): 80 02 00 00 00 00 F3 00 00 00 90 00h
Secure PIN Modify (Host->Reader): 69 1F 00 00 00 00 F4 00 00 00 01 00 89 47 04 00 00 0C
04 00 03 01 09 04 01 00 00 00 00 24 01 01 08 24 FF FF FF FF FF FF FFh
LCD display: "NEW PIN: (key)"
User enter 4 digits long new PIN: e.g. 1 2 3 4, and then press "OK"
LCD display: "CONFIRM PIN: (key)"
User enter 4 digits long new PIN again: e.g. 1 2 3 4, and then press "OK"
LCD display: "Card inserted""
Secure PIN Modify (Reader->Host): 80 02 00 00 00 00 F4 00 00 00 90 00h
2. For the implicit SECURE PIN MODIFY, host should send one command to do both the
verification and modification, for example:
Secure PIN Modify (Host->Reader): 69 29 00 00 00 00 CF 00 00 00 01 00 89 47 04 00 08 0C
04 03 03 03 09 04 00 01 02 00 00 00 00 24 00 01 10 24 FF FF FF FF FF FF FF 24 FF FF FF
FF FF FF FFh
LCD display: "Enter auth. Pin:"
User enter 4 digits long correct PIN: e.g. 1 2 3 4, and then press "OK"
LCD display: "NEW PIN: (key)"
User enter 4 digits long new PIN: e.g. 4 3 2 1, and then press "OK"
LCD display: "CONFIRM PIN: (key)"
User enter 4 digits long new PIN again: e.g. 4 3 2 1, and then press "OK"
LCD display: "Card inserted"
Secure PIN Modify (Reader->Host): 80 02 00 00 00 00 CF 00 00 00 90 00h
If the old pin is wrong during an implicit command, the response from the card should be "63
Cxh," where x is the number of remaining attempts until the pin is blocked, then we get an
error code "69 83h."
