The system is also characterized in that at least two switches (S1, S2, S*) are provided in the cash cartridge, the at least two switches (S1, S2, S*) are actuated automatically when the cash cartridge is inserted into the automated banking machine, the switch actuation sequence of the at least two switches (S1, S2, S*) is evaluated using pre-determined criteria for the generation of a manipulation alert.

Description

The invention relates to a manipulation recognition system for cash dispensers that can be used in cash dispensers. In this case, the generic cash boxes on a lockable Geldaus- / input port for the cash dispensing and / or cash input in the operating machine located in the ATM operating position.

For security reasons, it is important to know whether the cash dispenser / input port of the cashbox outside the ATM has been opened in an unauthorized manner for the removal of banknotes. It is of particular interest whether a) the cashbox was opened in the period between the filling with banknotes at a bank or a Werttransportunternehmen and their use in an ATM, and b) if the cashbox in the period between removal from an ATM and the official opening opened at a bank or a value-transport company.

For this reason, in the DE 690 04 906 T2 proposed that for manipulation detection via a sensor that detects the opening of the Geldaus- / input port, a tamper indication is generated on the cashbox. Such a manipulation indication can be used in particular for activating a inking unit arranged in the cashbox. In this case, the money contained in the cash box, in particular banknotes is made unusable by coloring with a special ink.

In a system of ATM and cashbox in which the Geldaus- / input opening is automatically opened when inserting into the ATM, eg via a slide guide, before reaching the operating position, this opening of the Geldaus- / input port is problematic insofar as this allowed opening by mistake to a manipulation indication at the cashbox leads. Such a tampering instruction would then lead to money cartridges with a Einärbeeinheit that the inking unit is activated in an undesirable manner, which would cause great harm.

The object of the invention is therefore to develop a tamper detection system that can distinguish in a simple and reliable manner between an allowable opening of the Geldaus- / input port of a cashbox inside the ATM and an unauthorized opening outside the ATM.

This object is solved by the features of patent claim 1. The subsequent subclaims contain advantageous embodiments of the invention.

According to the invention at least two, preferably three switches are provided in the cash box, which are each automatically actuated when inserting the cashbox in the ATM. In this case, the switching operation sequence of the at least two switches is evaluated on the basis of predefined criteria for generating a manipulation indication. The unauthorized opening the Geldaus- / input port outside the ATM always leads to a tamper indication and cash cassettes with Einärbeeinheit to an activation of the same, since the predefined Schaltbetätigungsreihenfolge not set in this case. The more switches are used, the more complex is the shift operation order and the more reliable the tamper detection. By using three switches, a very high level of reliability and safety is achieved at a reasonable cost.

According to the invention, an automatic teller machine is any machine for depositing and / or paying out money using cash cassettes. The term ATM covers both self-service and operated machines, eg so-called automatic cash safes. The generic ATM can also be operated in a commercial enterprise, for example in connection with a payment station as a so-called POS machine (Point Of Sales machine).

a block diagram of a cashbox with the components arranged therein.

In Figure 1A to Figure 1D schematically an ATM (1) with a cashbox (2) is shown, wherein different phases are shown when inserting the cashbox. The Geldaus- / input port is arranged substantially frontally on the cashbox (2). To close this opening, for example, a shutter or blind (shutter) is provided. In this case, the Geldaus- / input opening when inserting the cashbox (2) in the ATM (1) is automatically opened before reaching the operating position via a (not shown) slotted guide. This happens, for example, by sliding a blind. The displacement of the blind is shown schematically and marked with the reference numeral (2B). The insertion of the cashbox (2) is preferably carried out by inserting the cashbox (2) in a frame of the ATM (1).

In the cash box three switches (S1, S2, S *) are provided, which are automatically actuated when inserting the cashbox (2) in the ATM (1) in a specific, predefined order. In addition, the cashbox has a plug (2A) which is connected in the fully inserted position (operating position) with a mating connector (1C) of the ATM to a power and / or data transmission between the ATM and the cashbox (2) enable. As part of the ATM (1) is still a magnet (1A) shown schematically, whose function will be explained later.

In the presentation of Figure 1A the cashbox (2) has been inserted so far in the ATM (1) that the Geldaus- / input port is already opened slightly. At the time T0, the switch (S1) in the cash box (2) is actuated. The switch (S1) is preferably a mechanically actuable switch, for example a push-button switch, which is actuated for example by moving the blind or the shutter.

In the presentation of FIG. 1B is the cashbox (2) opposite the position of Figure 1A further inserted in the ATM (1). In this position, at time T1, the switch (S *) in the cash box (2) is operated. The switch (S *) is preferably a Hall switch, which is actuated when it detects a magnetic field with a magnetic field strength which is above a certain threshold. The Hall switch (S *) is thus actuated when the Hall switch (S *) during insertion of the cashbox (2) in the effective range of the cash machine (1) arranged magnet (1A) is moved. This is - as in Fig. 1B shown at the time T1, where the Hall switch (S *) and the magnet (1A) are directly opposite and the distance between the Hall switch (S *) and magnet (1A) is minimal.

In the presentation of Figure 1C is the cashbox (2) opposite the position of FIG. 1B further inserted in the ATM (1). In this position, the cash withdrawal / input port is already almost completely open. The Hall switch (S *) is no longer in the effective range of the magnet (1A) in this position. In this position, the switch (S2) is actuated at time T2. The switch (S2) is - as with the switch (S1) - preferably a mechanically actuated switch, such as a push-button switch, for example is operated by moving the shutter or the shutter.

In the presentation of FIG. 1D the cashbox (2) is in the fully retracted position, ie in the operating position. In this position, the cash withdrawal / input port is fully open. In addition, in this position, the plug (2A) of the cashbox (2) and the mating connector (1C) of the ATM (1) are electrically contacted with each other. In the operating position, money can be withdrawn from the cassette (2) and / or entered into it via a module (1B) disposed in the ATM (1).

The switching times T0, T1 and T2 are in the Figures 1A-1C symbolically marked at the points where the end face of the cashbox (2) has in each case reached the position in which the switch S1, S * or S2 is actuated.

The sequence of the switch operation (S1 → S * → S2), as it was explained with reference to the figures 1A-1 D, can also be found in the timing diagram of FIG. 2 again. Shown there is the switch position (also called switching state) for each of the switches (S1, S2, S *) compared to the time when inserting the cashbox (2). First, the switch (S1) is actuated, the operation of this switch (S1) defining the time T0. At time T2, the Hall switch (S *) is then actuated. As soon as the Hall switch has left the effective range of the magnet (1A) during further insertion of the cash box (2), the switching state of the Hall switch (S *) returns from "on" to "off". At time T2, the switch (S2) is then actuated as the last of the three switches.

In an embodiment of the invention, it is provided that the switches S1 and S2 remain in the "on" state after the actuation until the cashbox (2) is in the operating position at the time T _stop , what is detected by the plug contact (cash box plug / mating connector of the ATM).

In an alternative embodiment, it is provided that the switches S1 and S2 remain in the "on" state after actuation until the cash out / input opening is closed again after removal from the ATM (1).

In a further alternative embodiment, it is provided that the switches S1 and S2 automatically return to the state "off" after the actuation after a certain time from the state "on".

In this case, a manipulation indication is always generated when the detected Schaltbetätigungsreihenfolge does not correspond to the previously defined system according Schaltbetätigungsreihenfolge. The predefined switching operation order is determined as follows:

Actuate switch S1 (off → on), then press switch S * (off → on) and then switch S2 (off → on).

In a further developed variant, the predefined reset of the switch (S *) in the switching operation sequence is also interrogated:

Actuate switch S1 (off → on), then operate switch S * (off → on), then reset switch S * (on → off) and then switch S2 (off → on).

The more complex the predefined switching operation order, the more difficult it is to replicate it outside the ATM (1).

In addition, it is intended to interrogate not only the order of the switch operation per se, but also whether it takes place within a predetermined period of time (ΔT). For this reason, a mechanical insertion resistance (not shown) is provided, which must be overcome when inserting the cashbox (2) in time before the operation of the first switch (S1). To overcome the insertion resistance of the operator when inserting the cashbox (2) must spend a certain minimum force, which ensures that after overcoming the insertion resistance for the return of the subsequent Einsetzweges, then the three switches (S1, S *, S2) are operated , a maximum time is not exceeded. In other words, overcoming the insertion resistance causes sufficient momentum, so that the time period between the operation of the first switch (S1) and the last switch (S2) can be reduced to a calculable maximum dimension.

Furthermore, it is provided in one embodiment to also query the time intervals between the individual switch operations.

• festgelegte Reihenfolge der Schalterbetätigung und/oder Zurücksetzung, Zeitdauer für die Betätigung aller Schalter und/oder zeitliche Abstände zwischen einzelnen Schalterbetätigungen.

The predefined criteria by means of which the detected switch operating order is evaluated are therefore:

• fixed sequence of the switch operation and / or reset, duration for the operation of all switches and / or time intervals between individual switch operations.

Through the use of at least one non-mechanically operable switch S * (eg in the form of a Hall switch), which requires to actuate another on the ATM (1) arranged element (eg magnet), the reliability of the tamper detection system is significantly increased because a fraudulent replica of the Schaltbetätigungsreihenfolge accurate knowledge of the magnet, its strength, installation situation and distance to the Hall switch at the time of actuation requires.

In the manipulation detection system according to the invention, the generation of a manipulation indication is used, in particular, to activate a inking unit arranged in the cashbox (2) in order to be able to manipulate (in the cashbox (2) in case of manipulation (= unauthorized opening of the cash out / input opening outside the ATM). rendering ink unusable by inking. Alternatively or additionally, the manipulation indication can also be used to generate an optical and / or acoustic manipulation indication signal on the cashbox (2). The manipulation indication can also be stored as an entry in a manipulation memory (not shown) of the cashbox (2).

In one embodiment of the invention, it is contemplated to use the actuation of one of the three switches (S1, S2, S *) to generate a preliminary tamper indication, this tentative tamper indication being withdrawn if the evaluation of the switch operation order indicates that there is no tampering. Only if the evaluation of the switch operation order shows that there is a tampering, the provisional tamper indication becomes a final tamper indication, which then leads, for example, to the activation of a tinting unit. In particular, the use of the switch (S2) is suitable for generating a preliminary manipulation indication, since the switch (S2) is actuated when the cash dispensing / input opening is already almost completely opened.

The manipulation detection system according to the invention, which is also intended to prevent the generation of an unwanted manipulation indication when inserted into an ATM (1), has the advantage that it also works when the power supply of the ATM (1) fails when inserting the cashbox (2), since the switches (S1, S2, S *) and the evaluation for the tamper detection in the cashbox (2) are arranged, which via an independent power supply, eg via a Battery, features. Thus, a false triggering of the inking unit when inserting the cashbox (2) can be safely prevented even if the power supply of the ATM (1) fails.

FIG. 3 shows a block diagram of a cashbox with the components arranged therein. The battery supplies the remaining components with energy (current, voltage). In the operating position, the components can also be powered via the plug from the ATM with energy. The switching states of the three switches are queried and evaluated by an evaluation and control unit to check whether the queried switch operation order corresponds to the predefined criteria. The timer is started with the actuation of the first switch (S1), whereby the time T0 is defined. The actuation of the last switch (S2) at time T2 defines the end of the switch operation order, where ΔT = T2-T1.
