The control unit fixes which denominations are accepted for payment of the amount of money in dependence of at least one operating parameter, and/or fixes a maximum amount in dependence of the amount of money due, wherein the control unit controls the cash register system so that in the payment of the amount of money due only notes of value or combinations of notes of value are accepted whose value does not exceed the maximum amount. ## Claims ### Claim 1 An automatic cash register system, comprising a detection unit (12) for detecting goods to be paid for; a control unit (18) which determines an amount of money due; an input unit (16) for supplying notes of value for paying the amount of money; a sensor unit (22) for determining the denomination of the notes of value supplied, an output unit (20) for dispensing change, wherein the control unit (18), as a function of at least one current operating parameter, fixes which denominations are accepted for payment of the amount of money. ### Claim 2 (depends on 1) The automatic cash register system (10) according to claim 1, wherein the current operating parameter is the amount of money due. ### Claim 3 (depends on 2) The automatic cash register system (10) according to claim 2, wherein, for at least one denomination, a threshold value is stored in the control unit, that the control unit (18) compares the amount of money due with the threshold value, and that the control unit (18) controls the cash register system (10) so that a note of value of this denomination is accepted only if the amount due is smaller than the threshold value. ### Claim 4 (depends on 3) The automatic cash register system (10) according to claim 3, wherein, for each one of a plurality of denominations, preferably for each one of all denominations of a preset currency set a respective threshold value is preset, in dependence of which the control unit (18) fixes whether the corresponding denomination is accepted. ### Claim 5 (depends on 1) The automatic cash register system (10) according to claim 1 wherein, for at least one preset denomination, the control unit (18) determines the current stock of notes of value of this denomination in the cash register system (10), and that the control unit (18) in dependence of the current stock fixes of which denominations notes of value are accepted. ### Claim 6 (depends on 5) The automatic cash register system (10) according to claim 5, wherein, for all the denominations of a preset currency set, the control unit (18) determines the current stock of notes of value of the respective denomination in the cash register system (10), and that the control unit (18) in dependence of the current stocks fixes of which denominations notes of value are accepted. ### Claim 7 (depends on 6) The automatic cash register system (10) according to claim 6, wherein, for at least one denomination, information is stored in the control unit (18) that notes of value of this denomination are not accepted. ### Claim 8 (depends on 1) The automatic cash register system (10) according to claim 1 wherein the control unit (18), after supply of a note of value for payment of the amount of money due, determines the value of this note of value, wherein the control unit (18) then calculates a remaining amount still due if the value of the note of value is smaller than the amount of money due, and that the control unit (18) in dependence of at least one current operating parameter newly fixes which denominations are accepted for payment of the remaining amount. ### Claim 9 (depends on 8) The automatic cash register system (10) according to claim 8, wherein the control unit (18), in dependence of the remaining amount, fixes which denominations are accepted. ### Claim 10 (depends on 1) The automatic cash register system (10) according to claim 1 wherein the control unit (18) fixes a maximum amount in dependence of the amount of money due, and that the control unit (18) controls the cash register system (10) so that in the payment of the amount of money due only notes of value or combinations of notes of value are accepted whose value does not exceed the maximum amount. ### Claim 11 An automatic cash register system, comprising: a detection unit (12) for detecting goods to be paid for; a control unit (18) which determines an amount of money due; an input unit (16) for supplying notes of value for paying the amount of money; a sensor unit (22) for determining the denomination of the notes of value supplied, an output unit (20) for dispensing change, wherein the control unit (18) determines a maximum amount in dependence of the amount of money due, and wherein the control unit (18) controls the cash register system (10) so that in the payment of the amount of money due only notes of value or combinations of notes of value are accepted whose value does not exceed the maximum value. ### Claim 12 (depends on 11) The automatic cash register system (10) according to claim 11, wherein the control unit (18) determines the stock of notes of value of at least one determination, and that the control unit (10) determines the maximum amount in dependence of this stock. ### Claim 13 (depends on 11) The automatic cash register system (10) according to claim 11, wherein the control unit (18) determines the maximum amount by multiplying the amount of money due by a predetermined factor. ### Claim 14 (depends on 13) The automatic cash register system (10) according to claim 13, wherein the factor has a value between 1.1 and 3, in particular between 1.5 and 2. ### Claim 15 (depends on 11) The automatic cash register system (10) according to claim 11 wherein the control unit (18), after supply of a note of value for payment of the amount of money due, determines the value of this note of value, that the control unit (18) calculates a remaining amount still due if the value of the note of value is smaller than the amount of money due, and that the control unit (18) newly fixes the maximum amount in dependence of this remaining amount.
