QCard Recommendations
Always start a stack of pages with a Primary QCard.
Always end a stack of pages with a QCard, preferably an End-of-Document QCard.
A QCard can be inserted in between a stack of pages to signify a start of a new document to be processed, and a new coding process.
In a stack of pages, the pages between an End-of-Document QCard and any QCard will become unprocessed. Therefore, do not insert an End-of-Document QCard in between a stack of pages.
Refer from Qcard.
