LK - LOAD PIN KEY
Use the LK command to load a unique 4-digit key for PIN (personal identification number)
calculations. You can require your cardholders to enter a PIN for each transaction. This protects
the system from unauthorized use should a card be lost or stolen. You can set up the system to
automatically lock out the card after three unsuccessful PIN entries (see SC command, auto PIN
lockout feature).
The system generates PINs by taking this 4-digit number and the card information, and using an
algorithm to calculate a PIN number for each card. In this manner, all PIN numbers will be
different.
The 4-digit number you use in this command is assigned when you order your system. Your
assigned PIN key is indicated on the card layout provided with your Series 1000 Card Encoding
Manual. Do not change this PIN key number unless directed by an authorized service
representative (ASR).
1. At
the * prompt, type LK. The system displays PIN KEY NO.
2.
Type the 4-digit PIN key number and press RETURN. The * prompt reappears.

You can view the PIN number associated with a card by putting the system in diagnostic mode
and running test 0. See the Series 1000 Diagnostic Manual for details.
NOTE: If you are matching "A" System optical cards, you may not have this command.
