Packet Z60: Accept
and Encrypt PIN
(VISA Mode)
On receipt of the Z60 packet, Omni 33XX reads the user’s PIN from the keyboard,
echoing to the display an asterisk for each digit accepted. The PIN length can be
between 4 and 12 digits. There are two variations of the request packet: Master/
Session and DUKPT.

Sample Packet Z60
for DUKPT
Request <STX>Z60.[acct num]<FS>DUKPT ENCRYPTION<ETX>{LRC}
Response <STX>73.00000[key serial number]
[encrypted PIN block]<ETX>{LRC}
On receipt of a packet Z60 that contains the account number and working key (if
MS) or DUKPT ENCRYPTION (if DUKPT), the IPP gets the PIN from the user
then checks if MS or DUKPT is selected.
• If MS is selected, the IPP encrypts the formatted PIN block using the working
key that was decrypted using the selected master key. The IPP returns the
cipher-text PIN block using packet 71 (see MS Packet 71: Transfer PIN Block).
• If DUKPT is selected, the IPP encrypts the formatted block using the DUKPT
algorithm. The IPP returns the key serial number and cipher-text PIN block
using packet 73 (see DUKPT Packet 73: Transfer PIN Block (for Packets Z60
or Z63)).
