Method of operating automated teller machine in multi-sheet withdrawals
A method of operating a device ( 10 ) for handling banknotes detects multi-sheet withdrawals using a multi-sheet withdrawal sensor ( 30 ). If a multi-sheet withdrawal has been detected, at least the banknotes of the multi-sheet withdrawal are supplied to an input and/or output tray ( 22 ). Next, the banknotes are further separated. The denomination and/or number of the banknotes of the multi-sheet withdrawal is determined. The determined number and/or denomination is taken into account in the framework of the inventory management of the cash cassettes ( 16 ).
1. A method of operating an automated teller machine (ATM) comprising:
receiving a deposit of a first plurality of banknotes in an input and output tray of the ATM from a customer;
separating the first plurality of banknotes deposited in the input and output tray during said receiving with a separating unit of the ATM;
taking a second plurality banknotes out from one or more cash cassettes of the ATM in accordance with a disbursement request from an operator of the ATM;
detecting, with at least one multi-sheet withdrawal sensor of the ATM, a multi-sheet withdrawal among at least some of the second plurality of banknotes taken from the one or more cassettes of the ATM during said taking from the one or more cash cassettes;
transporting at least the multi-sheet withdrawal of the second plurality of banknotes, taken from the one or more cassettes of the ATM during said taking, to the input and output tray when the multi-sheet withdrawal has been detected during said detecting; and
separating, with the separating unit, the banknotes of the multi-sheet withdrawal after the multi-sheet withdrawal was transported to the input and output tray during said transporting.
2. The method of claim 1 , wherein only one multi-sheet withdrawal sensor for determining multi-sheet withdrawals is used for the banknotes taken out from all of the cash cassettes.
3. The method of claim 1 wherein said taking is further defined as taking the second plurality banknotes out from a plurality of cash cassettes of the ATM in accordance with a disbursement request from an operator of the ATM; and
wherein said method further comprises:
assigning a time stamp to each one of the banknotes that is taken out from one of the plurality of cash cassettes during said taking, said assigning executed prior to said detecting.
4. The method of claim 1 wherein:
said transporting further comprises transporting all of the second plurality of banknotes taken in response to the disbursement request during said taking to the input and output tray when the multi-sheet withdrawal has been detected including the multi-sheet withdrawal and single-sheet withdrawals of the second plurality of banknotes; and
said separating further comprises separating all of the second plurality of banknotes, including the multi-sheet withdrawal and single-sheet withdrawals of the second plurality of banknotes transported during said transporting, out from the input and output tray.
5. The method of claim 1 further comprising:
determining, with a reader unit and after said separating, the denomination of each of the separated banknotes of the multi-sheet withdrawal and the number of the separated banknotes of the multi-sheet withdrawal.
6. The method of claim 5 further comprising:
directing the separated banknotes of the multi-sheet withdrawal back to the input and output tray in response to said determining and in response to the disbursement request from the operator.
7. The method of claim 6 further comprising:
bypassing the one or more cash cassettes of the ATM and a reject cassette of the ATM during said directing of the separated banknotes of the multi-sheet withdrawal to the input and output tray.
8. The method of claim 6 further comprising:
storing the separated banknotes of the multi-sheet withdrawal in a temporary storage of the ATM after said determining and before said directing back to the input and output tray of the ATM, wherein the temporary storage of the ATM is distinct from the one or more cash cassettes of the ATM and a reject cassette of the ATM.
