Barred should only be used if the patron has more than one card in the system with charges/fines on all cards.
When you bar a patron please put a note on the Extended Info tab in the note field. The note should be in this format; HLC-TW-1/29/2015:The patron has another record in the system, ID #00000000. When the patron returns the items or pays the fines on this record the accounts will be combined.
If you have another reason you feel is appropriate to bar a patron please check with me. These policies are set by Operation Taskforce.
