A banknote handling system includes an unlocking system. The unlocking system includes a camera, a first mechanical arm to which one or a plurality of keys are affixed, and a controller that determines a position of a keyhole based on an image from the camera, and controls the first arm to insert one of the one or the plurality of keys into the keyhole and turn the inserted key for unlocking. In many examples, the unlocking system is configured to unlock a banknote cashbox.

A system includes a cassette including a bill storage component to retrievably store the plurality of bills, and a picker system to retrieve one or more bills stored in the bill storage component. The system further includes memory and one or more processors communicatively coupled to the cassette, the memory having instructions that, when executed by the one or more processors, cause the one or more processors to generate a bill list comprising bill information for each bill of the plurality of bills stored by the bill storage component where the bill information includes a denomination and a storage position of each of the plurality of bills, receive a transaction request, identify a storage position of a target bill from the bill list for dispensing based on the transaction request and a denomination of the target bill, and cause the picker system to retrieve the target bill for dispensing.

A currency arranging and stacking apparatus with a hopper for receiving a plurality of paper currency bills and a bill stacker for receiving and stacking unfolded and paper currency bills in a common orientation. Between the hopper and bill stacker, the apparatus includes a currency unfolding apparatus, the currency unfolding apparatus having a vacuum belt under negative pressure for holding the paper currency bills and a wheel engaging the vacuum belt that rotates at a speed different from the vacuum belt, thereby unfolding folded paper currency bills. A currency creasing apparatus comprising a first creasing wheel and a second creasing wheel, creases the paper currency bills to prevent them from re-folding before uniform assembly in the bill stacker.
