Security PIN on Violations - How is it used The Ticket PIN The  additional dash  and  2 digits  at the end of the violations are known as a " Ticket Security PIN ". It may look like it's part of the ticket number, but it's not. It's only used as a password for the ticket when appealing it. As an example when creating a violation, it appeared as  TT-10016-8T  The actual internal ticket number is TT-10016-8T, same format as it has always been. If you search violation TT-10016 in violation search it will appear as TT-10016. Additionally, if someone did type in the ticket number and PIN (TT-10016-8T) it would return the same ticket. This means the reports in the FTP file, for example, will only reference TT-10016 as the ticket number, not the additional -8T. Additionally, the code that generates the FTP files isn't going to change/add the pin. FTP reports will remain unchanged by the addition of the violation PIN. No PIN will be shown in the mailed out the violation. The PIN is only used when appealing tickets if the user isn't logged in. As an example, you can see the " Lookup your   Ticket " box on the login screen here.  The PIN is used in that box to give some protection from public users just looking up sequential ticket numbers. Click on the box that says " Lookup your   Ticket ". You should now see the following screen. Enter in the ticket number and PIN. Once you click check you will be presented with a screen that allows you to appeal or pay the ticket. Notice when the record of the ticket is found it does not include the PIN. Removing the Pin  If you wish to remove the  PIN  from the printed ticket, this can be done from the  System Settings  located under the  System Config  tab.  Look for  Violations  in the list of components on the left: Click on  Violations  to view and edit the settings. By default the setting for including a random PIN number to the ticket number when printed is enabled.  To remove the PIN, ensure that the  Include Random PIN on Handheld Tickets  box is toggled off.
