Sign On Password
Description A password of up to 10-characters is required to access the system Command
Mode for updating files and retrieving information. For security, the password is
not printed when entered into the system. The user can change the password.
Personal Identification Number (PIN)
Description PIN numbers can be used whenever a second account field entry is required and
when the PIN Entry configuration prompt is set to ENABLED. PINs are
calculated uniquely for each system by using an algorithm, the 4-digit PIN key,
and the second account field. The user can proceed with the transaction only if
the number entered matches the PIN calculated by the system.
Display
You can have the system calculate and display the PIN on the LCD display by
selecting diagnostic test 0 and entering the data for the second account field.
Lockout
Description The system operator can control access to the cardless system by
validating/invalidating vehicle records. This process is called lockout. Vehicle
records may be validated/invalidated individually or in strings of 10. If desired, the
system can lock out the entire vehicle file.
Sequence
In cardless systems, a user accesses the system by entering a vehicle number.
This vehicle number corresponds to a record in the vehicle file. When the number
is entered, the system checks to see if a vehicle record exists. If one does, the
system checks two fields: Lockout Flag, to see if the vehicle record is valid and
Check Digit Code to see if a second account field (usually Employee) is required
for access.
If the lockout flag is set to N the vehicle record is valid and not locked out. (If the
record is invalid, the lockout flag will be set to Y and no access will be allowed.) If
the check digit requires a second account entry, the user enters the second entry.
The system then checks the second account file (Employee) to see if the second
entry is valid. The second account file is totally separate from the vehicle file and
can be positive or negative. A positive file contains only numbers which are valid;
the number is locked out if it is not in the file. A negative file contains only those
numbers which are invalid; the number is locked out if it is in the file.
