Description

 Mobile input device for entering PIN numbers at transaction machines

The invention relates to a mobile input device for actuating a keypad comprising a plurality of keys of an authentication or transaction machine, in particular for entering a number sequence on a keypad of a payment transaction machine.

The entry of secret numbers in the keypad of ATMs is not always under consideration of the required discretion by other present, if they do not maintain an appropriate discretion distance and creates the feeling of unwanted observation.

There are increasing rates of fraud with EC cards in the media. In particular, cases of fraud occur in which fraudsters by means of a hidden hidden in the vicinity of the EC machine micro-camera, the secret numbers, d. H. the PIN codes, individual debit cards and withdraw with the help of illegally produced debit card duplicates (so-called "white cards") substantial sums of money from the bank accounts of the injured party.

Even outside the use of ATMs, the entry of secret numbers at payment machines in supermarkets, petrol stations or department stores is now very common. Again, there is the danger of spying on the PIN code by third parties by direct insight contact or by means of mobile phones, which are also equipped with a camera.

The arrangement of keyboards of payment or automatic cash dispensers is standardized. Three buttons are arranged side by side. The numbers one through nine are arranged in three rows of keys arranged one below the other, the numbers continuing from row to row. The number zero is arranged in a fourth row of keys on the middle key. The key corresponding to the number 5 is provided in the middle with a formed elevation which serves as orientation e.g. for the visually impaired, serves. The keys have largely uniform dimensions and distances to each other.

The invention has for its object to provide an input device that in the entry of PIN numbers in a keypad unauthorized access during the Prevents secret entry and serves as a privacy screen for insight prevention during secret code entry at ATMs.

This object is achieved with an input device of the type mentioned above in that the device is equipped with an integrated in a housing and can be placed on the keypad actuator field with at least one actuator or a plurality of actuators, or according to a triggered by an operator Action acts on selected keys in accordance with a predeterminable by the operator sequence or act.

An advantage of this device is that the input device also provides people with poor eyesight with the ease of entering digits. The input device has dimensions that allow it to be carried like a small pocket calculator or a cell phone.

Advantageous developments of the invention will become apparent from the dependent claims.

Advantageously, it can be provided that the actuators are programmed and / or activated by an action acting on a haptic, optical or acoustic sensor by the operator.

In an advantageous embodiment, it is provided that the actuators are programmed by a configuration field at least in a first configuration, d. H. in a digit sequence of, for example, four digits, as corresponds to a common secret number, and the operation of the keys of the keypad is made according to a configuration by a predetermined or user-definable signal. Several codes can be stored in the input device so that the user can use different debit or credit cards at ATMs or other transaction machines whose use requires a different PIN. However, a configuration for triggering the operation of keys of a keypad may include more or fewer digits than the number of digits in the secret number.

In a further embodiment, it is advantageously provided that the actuators are arranged on the side of the input device facing the keypad and the configuration field is arranged on the side of the input field facing the operator. An advantage is also an input device in which the actuators are each actuated individually by motor, mechanical, electro-mechanical, pneumatic, e'ektrostriktiv or actuated by the use of the inverse piezoelectric effect tripping means.

Another advantageous embodiment of the input device is that it comprises means for authenticating such persons who are authorized to use. Then, the input device, after authentication, the configuration by the operator, in particular the use of a user-to-use keyboard, free. In accordance with an operation made by the operator, a certain sequence of the actuation of the actuators for acting on the keypad of the machine is then triggered.

It also proves to be advantageous if the means for authenticating a sensor for measuring biometric data, in particular an optical or photographic sensor for scanning the iris or retina of the eye or the whole face, for scanning a fingerprint, an acoustic sensor for determining the voice or a combination of sensors.

One possibility of authentication is that the user on a keypad of the input device a code (so-called master code) -. the date of birth - to identify itself to the input device, which code differs from the secret numbers, which are then entered by the actuators of the input device through the programmed operation in the keypad of the machine.

Advantageous is a cross-stage control, with which a single actuator can be controlled, which occupies the positions one after the other, which moves the sequence of corresponding to the sequence of secret numbers to be actuated keys of the keypad of the machine and presses each of them.

An alternative drive means for actuating a plurality of actuators consists in a cam roller whose cams actuate actuators in a specific order.

An input device according to the invention has an upper side accessible to the user during use (FIGS. 1, 2), which is equipped with keys or other actuating means for start, input and start functions. These are in detail: An input field 7, which can be closed by a cover, allows the input of at least one or more current PIN numbers, which are then, in each case selectable, in a transaction by start button 6 for the corresponding bank card can be retrieved. Light-emitting diodes 1 for indicating readiness for operation (red) and light-emitting diodes 2, 3, 4 and 5 (green) indicate, in succession by lighting up, the successful activation or pressing of the corresponding part of the PIN number.

Alternatively or additionally, a touch screen 6a is provided in the central area of the input device with a biometric data reader, e.g. Fingerprints enabled, which enables the release of the secret code input by the authorized person. The release can also be done here optionally with a lock / key.

The underside (FIG. 3) of the input device 11 is divided into ten compartments 13 corresponding to a keyboard arrangement of a cash dispenser. Alternatively, as many as twelve trays can be operated if the keypad of the machine allows access to an asterisk ( ^* ) and a hash (#) key.

In each of these compartments 13, an actuator 14 is arranged with a miniature electric drive which drives a lowerable pin 15 and which lowers in use to the selected and released by the user by input side configuration key of the ATM and thus a portion of the required PIN Number triggers. This process is carried out consecutively without interruption according to the secret number length.

The housing 11 includes magnetic surfaces or spots (FIG. 4) with which the housing 11 can adhere to a keyboard surface 16. The miniature motors / actuators 14 with integrated release pin 15, and the keyboard buttons 17 are also shown schematically.

The invention "mobile input device for PIN numbers at the ATM" can be divided into three subsystems, whereby the subsystems are assigned the following tasks:

1st Subsystem 1 is responsible for the control of the overall system,

2. Subsystem 2 realizes the key operation, 3. Subsystem 3 authenticates the user. Subsystem 1: The controller

The controller performs the following tasks: issuing the control commands for the actuators to actuate keys on the cash dispenser, recording the current actuator position / requesting actuator activity, collecting and processing the user inputs and commands, outputting program-controlled signals to the user, validating the results authentication, battery voltage monitoring.

These tasks are done by a suitably programmed integrated circuit, so for example by a commercially available microcontroller.

However, other types of integrated circuits can also be used to control the system; conceivable is the application of a FPGA (Field Programmable Gate Array) or CPLD (Complex Programmable Logic Devices). Alternatively, the control can also be realized from logic components, in particular in combination with a discretely constructed circuit.

Since a considerable amount of power is needed to control the actuators, corresponding driver stages must be connected to the controller. Depending on the power requirements, both discrete power amplifiers such as a transistor stage or a MOSFET driver can be used as well as integrated circuits. An example of the latter is about the 7-fold Darlington ULN2003.

The user input can be queried via a keyboard matrix or via the individual query of the buttons. The advantage of the single query is this: If several keys are pressed at the same time, an unambiguous assignment can be made. This is not the case with matrix and voltage divider solutions.

In the individual query, the buttons should be connected to a defined voltage level via an appropriately dimensioned resistor in order to generate a clear level. There are two connection options, PuII-Up (connection to the supply voltage) and Pull-Down (connection to ground). The connection type must be taken into account when programming the controller. Many today's microcontrollers have internal pull-up resistors, eliminating the need for external circuitry, and allowing the pushbuttons to be connected directly.

With a larger number of individually connected buttons, the physical connection options available on the controller may not be sufficient. To solve this problem, several possibilities are conceivable:

Connection of pushbuttons via shift register, connection of pushbuttons via port expander, which are connected via a bus. Common is the connection via a SP! or I2C bus.

The button groups can be connected to resistor networks. Since each probe pressure produces a different voltage drop in the branch, the resulting voltage, transformed by an analog-to-digital converter, can be uniquely assigned to a key by the controller. Many of today's microcontrollers contain several internal analog-to-digital converters, which allow the direct connection of voltage divider networks, and make the circuit construction more cost-effective.

The organization of keys in a matrix requires a row or column query. Typically, this arrangement is used in foil keyboards.

Because of the cheap (and very customizable) production and the low cost, this type of keyboard is especially recommended for this purpose. The query of the matrix is quite simple with an IC, but the unique assignment of the keys can only work if exactly one key is pressed at the moment of determination. If more keys are pressed, this is no longer possible.

The power supply of the controller can be done by built-in batteries or batteries. Alternatively, high-capacitance capacitors (so-called gold caps) are possible. Regulated power supplies (for example, for the household power grid or for the on-board network of motor vehicles) as well as voltage-supplying bus systems are suitable for charging the voltage memory. An example of this is the universal serial bus, or USB port, which can often be found in the PC area. The battery voltage is monitored by the controller itself, either through a comparator (compares a reference voltage to the battery voltage) or through the use of an internal or external Anglog-Digital Wandlsrs.

Alternatively, the battery voltage may also be compared to a threshold. For this purpose, in the simplest case, a series combination of a suitably selected Zener diode (Zener diode) and a series resistor is used. If the Z voltage is undershot, the diode blocks and thus changes the falling voltage in the branch. Although this method is very cheap to implement, the application must be carefully weighed because the power consumption is not insignificant.

When using a microcontroller for control, data loss in battery replacement can be easily prevented by writing relevant data (stored PIN numbers, authentication codes, etc.) in the nonvolatile memory area (flash memory) of the microcontroller. Today's microcontrollers have mechanisms that effectively protect this memory area and prevent unauthorized reading - for example, if the device is lost.

The connection of the controller with other subsystems or possible expansion modules is usually via a bus system or via one or more GPIO (General Purpose Input / Output) lines of the controller. Suitable bus systems are, for example, the TWI bus (two-wire interface), the SPI bus (serial peripheral interface) or comparable systems. The speed request to the data bus is rather low.

The presentation of user information is in the simplest form by coded output on one or more LED (Light Emitting Diode) (light emitting diode). This can consist in both turning on and off a diode (e.g., standby indicator) as well as displaying signal patterns on multiple elements (e.g., warning the user about low battery voltage). For programming with different light signals, an appropriate program schedule must be used.

Better and more up-to-date user information can be achieved through a display integrated into the system. In addition to any user request and information display, it can also be used for user guidance in menus. This allows further accessories to be well integrated. Conceivable applications are, for example, a music player, a clock, an alarm clock, a digital navigation system, a personal alarm system, a USB mass storage, mini-video games, cosmetics utensils (see Fig. 10) and / or an FM device (radio).

Subsystem 2: Operation of the buttons

The force required to operate the ATM keys is not insignificant and must be generated by actuators that are electronically positioned by the control unit and - depending on the type of mechanical structure - measured. For the mechanical realization different approaches are possible:

Each key in the cash dispenser keypad is operated by a specially reserved actuator. This actuator comprises, for example, a coil with a movable core, so that when the coil is energized, the core is lifted and actuates a key of the keypad. Or there is an engine with a correspondingly designed gear available. A total of ten (or in individual cases) twelve actuators are available.

The advantages of this approach are that it is mechanically very resistant to interference, since no major moving parts are included and there is no risk of trapping fingers, clothing, etc.

Exactly one actuator is responsible for the operation of the keys on the ATM. The positioning of the actuator via the keypad is done in the manner of a cross table, which allows the control of all keys in the horizontal and vertical direction in the keyboard field level. As actuators for the operation of the keys also come here coils or motors in question. Only motors can be used for positioning. Here, for example, three actuators are needed and two motors.

The advantages of this solution are the small number of actuators, so that there are only a few possibilities for error. Furthermore, the input device in this embodiment has a low weight. The keypad is divided into horizontal or vertical groups, with a vertical division being more favorable due to the smaller number of groups. (The further description refers to this variant.) The now resulting groups (about 2, 5, δ, 0), which result from the middle, vertically arranged keyboard elements of the ATM come with the respectively associated and only vertical actuated sliding actuators. As actuators come in addition to coils and motors and mechanical constructs into consideration, which can significantly reduce production costs. In this case, for example, four motors are needed. The risk of trapping is excluded.

In each case two keys of the ATM are actuated by an axially rotatable cam roller. This solution does not require precise knowledge of the roller position, only the neutral position must be - for example by a cam or notch on the roller, which operates a miniature switch - be recognizable. For the cover of the entire keypad, for example, six rollers, each with a drive motor required. In order not to overload the drive motor in the end position, the current consumption of the motor is monitored, or there is a Auskuppelmechanismus.

This embodiment has the advantages that it is very space-saving, since the drive can be integrated in the roller. The production is favorable, since only a few moving parts must be made with low tolerance requirements. At the same time the operational safety is high, the risk of jamming is excluded. By using a planetary gear high forces can be exercised with a simple design by a motor.

In Figs. 7 to 9 is an illustration of this solution. The reference symbols used stand for:

11 housing of the input device,

16 input keys at the ATM, 17 keypad at the ATM

20 miniature switches for detecting the neutral position

21 Cam of the neutral position on the roller

22 Cam on the roller for operating the bank machine key

23 cam roller 24 planetary gear 25 drive motor

Subsystem 3 User Authentication

An important part of the system is the unambiguous assignment of the device to the authorized user, otherwise misuse may be possible if the device is lost. For this purpose, the identity of the user must be confirmed either by biometric data collection or by appropriate identification measures.

Biometric capture: This captures physical features of the user and compares them with stored data. Technically feasible is the collection of the following features:

^■ fingerprint

^■ Iris or retina

^■ face

^■ Language

However, some of these features can not unequivocally identify a user, such as speech may be faked by a sound recording.

Other identification methods: Authorization of the user can also be done by requesting a personal master PIN code. As a result, only a freely selectable number combination must be noted for all stored PIN numbers. This solution is easy to implement and is very cost effective due to the hardware available.

Another option is to "unlock" the device, ie to use a switch key, so that the owner of the key has access to all stored functionalities.

It is also conceivable to use a personal transceiver (or transceiver transceiver) pair. The transmitter is carried close to the body of the user (wallet, watch, etc.), the receiver is firmly installed in the PIN input device. By measuring the signal strength, the distance of the user can be determined and thus a use of the device can be prevented in the absence. By issuing a beep, the owner can be notified in case of forgetfulness or distraction.

In one embodiment, the housing of the input device 11 is magnetically formed at the bottom at some points, so that the device in the application exactly centered in the automatic keyboard is placed. If the surface of a transaction machine in the area of the keyboard is made of a magnetic material, sticking of the input device 11 during a transaction is easily possible.

Due to the working nature of the input device during a current transaction, a durable counterpressure in the form of e.g. Magnetic adhesion can be generated, otherwise the entire device would stand out and thus the programmed selection of the PIN number in the area of the keyboard would not be triggered. Alternatively, the entire device may also be manually pressed and held during a transaction.

The user can now enter his secret number using the automatic input device according to the invention, without an unauthorized person can follow the input and sequence.

It offers a serial production in larger quantities, which then benefits the cost-effective acquisition. Furthermore, it lends itself to distribute the invention as an advertising medium with the inclusion of the above-mentioned multiple uses of various categories, since sufficient advertising space is available.
