You can use wildcard lockout to lock out selected fields of the customer information. For
example, if a system uses a 14-digit account number, where the first six digits are the card
number, the next four digits are the employee number and the last four digits are the vehicle
number, you can lock out only the card number, only the employee number, only the vehicle
number, or any combination of card number, employee number, or vehicle number.
If the account number format is as given above,
• To lock out employee number 1234, enter: LOCK CARD ......1234....
• To lock out vehicle number 4567, enter: LOCK CARD ..........4567
• To lock out the exact combination of employee number 1234 and vehicle number 4567,
enter: LOCK CARD ......12344567
If you use wildcards with the commands LOCK CARD, UNLOCK CARD, or CHECK
CARD, and there is not an exact match, the terminal will print Some valid, some not. This
does not necessarily mean that there are both valid and invalid card numbers in the group.
If you use wildcards to lock out or unlock account numbers, you cannot unlock or lock an
account number that matches the wildcard number. For example, if you use LOCK CARD to
lock out number 11.4, you cannot unlock account number 1114. If you try to unlock an account
number that matches a wildcard number that is locked out, the terminal prints Card is not
valid. If you try to lock an account number that matches a wildcard number that is unlocked,
the terminal prints Card is valid.
Positive and Negative Lockout Options
You must choose one of two card lockout options, positive lockout or negative lockout.
• If you choose the negative lockout option, all cards are initially valid and you enter invalid
card numbers into the Site Controller.
• If you choose the positive lockout option, all cards are initially invalid and you enter all
valid card numbers into the Site Controller.
