Abstract: A bank checking system for carrying and recording standard size checks is adapted for storage in a pocket compartment of a wallet. The system includes a cover member which may be opened and closed on a fold line. One half of the folding member holds a plurality of sequentially numbered, standard size checks folded and stacked such that they may be removed in sequence without disturbing the remaining checks. The other half of the folding member holds a register including a continuous sheet folded into collapsible segments.
