Description




BACKGROUND OF THE INVENTION




This invention relates to a terminal, such as a self-service terminal (SST), and typically an automated teller machine (ATM). Aspects of the invention also relate to a terminal for carrying out non-cash transactions, such as in outlets where customers purchase goods or services using credit or debit cards.




A conventional self-service terminal (SST), such as an automated teller machine (ATM), includes a card reader device to initiate a transaction, a keypad to input information and instructions to the terminal and a display to output instructions and information to the user. These devices are expensive and require a level of assumed knowledge and effort from the user.




In addition, these devices must be located conveniently for users of the terminal. In practice, a terminal will typically be set out in a compromise configuration; of course such a configuration may involve some difficulty for users who are shorter or taller than average, and will likely prove difficult if not impossible to access by wheelchair users. A somewhat similar difficulty arises in “drive-up” applications, where it is intended that the user may complete a transaction or operation using the terminal without leaving their vehicle. In this application, the terminal must attempt to accommodate variations in vehicle configuration as well as physical differences in users.




SUMMARY OF THE INVENTION




It is among the objectives of aspects of the present invention to provide a self-service terminal which obviates or mitigates these difficulties.




According to a first aspect of the present invention there is provided a self-service terminal comprising:




non-contact interface means for enabling a user to interact with the terminal without requiring physical contact with the terminal,




biometric sensing means for establishing the identity of the user by sensing a physical trait or characteristic of the user; and




processor means for controlling the terminal.




According to a second aspect of the present invention there is provided a method of operating a self-service terminal, the method comprising:




enabling a user to interact with the terminal without requiring physical contact with the terminal; and




establishing the identity of the user by sensing a physical trait or characteristic of the user.




The provision of non-contact interface means in combination with biometric sensing means allows a user to interact with a terminal while requiring little or no physical contact or interaction with the terminal. This offers a number of significant advantages over existing terminals. For example, where the terminal is an ATM, it may be possible to dispense with a number of features found in conventional ATMs, such as the card reader device and input slot, the keypad to input information and the display. Accordingly, it may be possible to provide an ATM in accordance with the invention at significantly lower cost. Further, as there may be little or no need to interact with the terminal physically, a terminal may be made more easily accessible to users of a wide variety of statures and wheelchair users. Similarly, in “drive-through” applications, a terminal may be more easily accessed by users in a variety of vehicles. In preferred embodiments of the present invention in the form of ATMs, the only physical contact the user has with the terminal may be to withdraw banknotes from an appropriate cash dispenser slot.




The non-contact interface means may include one or both of means for outputting terminal instructions for the user in natural speech and means for inputting spoken user instructions for the terminal. Thus, the terminal and user may “converse”.




The biometric sensing means may take any suitable form, preferably utilizing a non-contact technique such as iris pattern recognition, but said means may use other biometric patterns including facial geometry, fingerprints, palmprints, voice patterns, finger geometry or other physical traits or characteristics, or a combination of one or more of these.




Preferably, the biometric sensing means identifies the user, such that an operator may utilize the terminal without having to present a identification card or the like. Alternatively, said means may be used to verify the identity of a user, where the user has “claimed” an identity by presenting a means for identifying themself, such as an identification card or the like, to the terminal. In such an embodiment it is preferred that the identifying means does not require physical contact with the terminal, such as an identification card that may be read by the terminal using a camera of the like, or is capable of remote interrogation or communication with the terminal.




In order to establish the identity of a user by one or more biometric identifiers, it is of course first necessary to create a record of the user's biometric identifiers, which allows comparison between a biometric identifier sensed by the terminal and the stored information. When a best match is made, the user is offered the services available from the terminal. The information may be stored on a “smart” card carried by the user, or may be stored in a central database.




According to another aspect of the present invention there is provided a non-cash transaction terminal comprising:




interface means for enabling entry of transaction details;




biometric sensing means for identifying a user by sensing a physical trait or characteristic of the user; and




processor means for controlling the terminal.




According to a further aspect of the present invention there is provided a method of carrying out a non-cash transaction, the method comprising:




providing a terminal;




entering transaction details in the terminal; and




identifying a user by sensing a physical trait or characteristic of the user; and




processing the transaction.




These aspects of the invention have application in retail stores and the like where users or customers wish to purchase goods or services. As the customer is identified by the terminal, there is no requirement for the customer to present a credit or debit card. Clearly this is more convenient for the customer and minimizes the possibility of fraud; a thief cannot obtain or “steal” an individual's biometric identifiers, whether this is an iris pattern or other identifier.











BRIEF DESCRIPTION OF THE DRAWINGS




These and other aspects of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:





FIG. 1

is a block diagram of a self-service terminal (SST), in the from of an automated teller machine (ATM), in accordance with an embodiment of one aspect of the present invention; and





FIG. 2

is a block diagram of a non-cash transaction terminal in accordance with an embodiment of another aspect of the present invention.











DETAILED DESCRIPTION




Reference is first made to

FIG. 1

of the drawings which is a block diagram representation of a self-service terminal, in the form of an ATM


10


, in accordance with an embodiment of a first aspect of the present invention.




The ATM


10


has a user interface


12


, incorporating a number of features and facilities, illustrated as individual modules. In the illustrated embodiment, these features include a camera


14


, a non-contact card reader


16


, a loudspeaker and speech generator


18


, a microphone and speech processor


20


and a receipt printer


22


, which is associated with a receipt printer slot (not shown) provided in the face of the machine.





FIG. 1

also shows a cash dispenser module


24


which is associated with a cash dispenser slot in the face of the machine, and a biometrics sensing processor unit


26


which operates in association with the camera


14


, as will be described.




The ATM


10


further comprises processor means in the form of a controller unit


28


which communicates with components of the interface module block


12


, with the cash dispenser module


24


, and with the biometrics sensing processor unit


26


. In a typical ATM, the controlling unit


28


will also communicate with an operator panel (not shown).




The controller unit


28


includes a processor unit


30


and a non-volatile memory


32


implemented by a micro-computer having non-volatile RAM.




The ATM


10


is used in conjunction with smart cards


34


which contain details of the user's selected biometric identifier.




In use, the user approaches the terminal


10


and places or holds the card


34


adjacent the terminal


10


such that the card reader


16


may read the customer details from the card


34


and initiate a transaction. Once the user has been identified, the camera


14


records an image of the iris pattern of the user and the image is conveyed, via the processor unit


30


, to the biometrics sensing unit


26


where the iris pattern data read from the card


34


, in the form of an enrolment template, is compared with the data received from the camera


14


. Typically, the information stored on the card


34


will be in the form of an iris code, representing a processed image of the user's iris. The biometric sensing unit


26


processes the image received from the camera


14


to create a current iris code, or current template which is compared with the enrolment template stored on the card


34


, to verify the identity of the user.




Typically, the enrolment template, in the form of a sequence of binary digits, is compared with the current template, also a sequence of binary digits, on a bit-by-bit basis using an exclusive OR function. To improve the speed of the comparison, all of the bit comparisons are performed simultaneously. The two templates match if they differ by less than a predetermined number of bits.




If the identity of the user is verified by the biometrics sensing unit


26


, then the user is allowed to access the facilities provided by the ATM


10


and a menu of the various transactions available to the user may be relayed to the user, in natural speech, via the speech generator and loudspeaker


18


. User responses are made via the microphone and speech processor


20


.




It will be apparent to those of skill in the art that the ATM


10


allows users to interact with the ATM


10


with little or no physical contact with the ATM


10


, a user only having to make their smart card


34


visible to the card reader


16


, converse with the terminal


10


via the speech generator and loudspeaker


18


and the microphone and speech processor


20


, and then retrieve any banknotes or receipts issued by the cash dispenser module


24


or receipt printer


22


. Accordingly, the ATM


10


is easily accessible to a wide range of users. Further, the absence of a requirement to provide, for example, a display and keypad, allow greater flexibility in the configuration of user interfaces, and also minimizes the expense associated with the provision of such interfaces.




In other embodiments of this aspect of the present invention a self-service terminal may include a display or other features of a conventional ATM user interface panel.




In still further embodiments of this aspect of the present invention, the card reader


16


may be omitted, user identification being achieved solely by iris pattern recognition, or some other biometric sensing technique. For added security, and to accommodate imperfect biometric sensing, a plurality of biometric identifiers may be employed.




Reference is now made to

FIG. 2

of the drawings, which is a block diagram of a noncash transaction terminal


110


in accordance with an embodiment of another aspect of the present invention. The terminal


110


is of the type commonly found in retail outlets, to allow a customer to purchase goods or services using a credit card or debit card.




The terminal


110


shares a number of functional features with the ATM


10


described above, and common functional elements are designated in

FIG. 2

with the same numerals as the ATM illustrated in

FIG. 1

, prefixed by a “1”.




In the illustrated embodiment, the terminal


110


is intended to operate without the use of a smart card, and utilizes a camera


114


which operates in conjunction with a biometric sensing processor unit


126


to identify the user. The terminal


110


is also provided with a keypad


142


to allow a sales assistant or the like to enter details of a transaction, for example the purchase price of an item. A display


140


is provided to allow verification of the information entered via the keypad


142


, and may be used to display other messages and information as desired. To provide a hard copy record of a transaction, the terminal


110


also incorporates a receipt printer


122


.




Whereas the iris code of the first embodiment described above was stored on a smart card


34


, in this embodiment the iris code is stored in a remote database


134


, the terminal processor unit


130


communicating with the database


134


as required.




In use, a user will register with a financial institution and an image of the iris pattern of one eye of the user is recorded and translated to the appropriate iris code and entered in the database


134


.




If the user is a customer in a retail outlet and wishes to purchase some goods, a sales assistant directs the customer action to allow the biometrics examination to take place, for example by asking the customer to look towards the camera


114


. If the customer has a number of accounts or payment options, the customer will also be asked to select the method of payment, which information may be entered via the keypad. The biometric sensing unit


126


then examines the iris pattern recorded by the camera


114


, and then forwards the encoded biometrics details to the remote database


134


for identification. Once the customer has been identified the transaction is carried out in a secure manner.




It will be apparent to those of skill in the art that this embodiment offers the significant advantage that the customer need not carry or present a credit card or debit card, and thus the possibility of fraud is substantially reduced.




In other embodiments of this aspect of the present invention, a smart card, similar to the smart card


34


described above, could be utilized, rather than relying upon access to a remote database


134


.
