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.
